History
History[]
Background[]
At some point after the Serpentine tribes were freed from their tombs, Reginald and a female Serpentine from the Venomari tribe[1] had a child named Frak. At some point later, the family relocated to the neighborhood close to Ninjago City, joining in the human society. During his life, Reginald would take an interest in archaeology, but because he lived in a society and a point in time where prejudice against Serpentine was intense, he knew he had to work twice as hard and twice as long in order to earn any recognition, leading him to put his career over his own family. Reginald eventually earned two doctorates, one in "Advanced Adventure-Archaeology" and another in "Whip-Crack-ology", giving him two academic titles to his name. He would become renowned as an explorer, facing challenges in the Quicksand Pit of Greater Lamar and the sacred Leviathan Temple, and became the only non-Tide-Folk to ever dance in the ritual fire-waltz ceremony with the Lava-Tides. His feats would ultimately make him the first Serpentine to be admitted into the Explorer's Club.[2] Before the Merge, he and his family moved away from the district where they used to live.
Reginald has a very complicated relationship with his son, which is rooted on his desire to build a legacy which not only he, but also his son would be proud of. During the little time he spent with his son, he was mostly controlling, perfectionistic, and demeaning toward him, leading Frak to develop resentment towards him.[3]
During his time at the Explorer's Club, Reginald worked alongside a team of archaeologists that included Johnny Courageous, Rowan Rockspike, Seafoam Green, and Gweeg, unaware that Johnny was actually a Loyalist spy.[3] Reginald often picked on Gweeg, treating him poorly under the guise of bonding. In one of their adventures, they even hired a slug creature, which Reginald humorously called Frak.[4]
Cursed![]
As Kreel and Lobbo were waiting for their tour guide in Explorer's Clubhouse, Reginald arrived. Kreel wanted her to move on, but Lobbo said this guy could be their tour guide, which was confirmed by him. Then, Reginald introduced himself, but Kreel said they never heard of him. So, Reginald went on about his adventures, much to Kreel's confusion. When Lobbo pointed out the fact that he says "doctor" twice, Reginald explained that he has two doctorates, which Kreel found dumb. However, she ignored it and said she wants to see some treasure, which in response Reginald took them to the Explorer's Club's treasure vault where he showed them various artifacts, while also adding the fact that they were cursed. When Lobbo pointed out a musical instrument-looking artifact, Reginald said that's the great Flugelhorn of Tomport, made from pure Grundle bone, and also included the fact that blowing this flugelhorn will summon the end of all existence. Hearing him wrong, Lobbo tried to play the flugelhorn, much to Kreel and Reginald's worries. Thankfully, Kreel was able to shove him. However, Reginald pointing out the fact that she broke Vase of the Scarab Queen, which was also cursed. Then, the Phantom Scarabs of Dread came up from the vase, scaring them. In anger, Reginald got Kreel and Lobbo out of the vault, saying they caused enough problems, whilst also shutting the vault's door. Then, Reginald tried to fight against them. Lobbo expressed that he feels bad, but Kreel can't do anything since Reginald's closed the vault. As they ended the episode of the Crossroads' Crosstalk, Reginald continued his battle against the scarabs.
The Lean of a Tree[]
Reginald Slitherbottom led his team to capture a Mutation Monster in Umbrasilvis, using the Expanding Frontier for their journey. Upon their arrival and while setting up, Reginald unexpectedly ran into his son, Frak.
Tonight We Hunt Monsters[]
The ninja were surprised to discover that Reginald was actually Frak's father. With a sense of pride, Reginald proclaimed that it was an honor for Frak to be his son, much to Frak's embarrassment and the irritation of his friends. He then introduced his colleagues, but Wyldfyre found their names rather silly. Reginald appreciated Wyldfyre's attitude. Reginald was surprised by Johnny's memory of rembering Frak, acknowledging that he sometimes had a knack for remembering details. To Reginald's astonishment, he learned that Frak's friends were ninja, but he was more concerned about the classic six ninja, whom he regarded as the true ninja with a reputation, unlike Frak and his companions. This comment struck a nerve with Frak's friends, leading Frak to defend them and even claim that Lloyd viewed him as an excellent student. However, Reginald dismissed this, suggesting that Frak was merely a passable student because of their familial connection. Sora then asked Reginald to take them to Ninjago, to which he agreed, but. However, they first needed to capture the Mutation Monster that was on the loose before heading back. Frak emphasized the urgency of returning to Ninjago, but Reginald misinterpreted this as a need for Frak to tidy up the ninja's weapons and monastery. Reginald insisted that for the Explorer's Club to regain its glory, capturing the Mutation Monster was essential. He offered Frak and his friends the chance to join the mission, suggesting that Frak could learn a thing or two.
Reginald demonstrated a net launcher to the Explorer’s Club, using Gweeg as a test subject for its effectiveness. As they prepared to split up for their expedition, Frak voiced his concerns, arguing that it would be unwise and insisting that they should stick together. He then apologized to his colleagues for what he perceived as his son’s naivety, informing Frak that the person who successfully captured the Mutation Monster would have the honor of naming it. While Reginald dismissed Frak’s suggestion as poor, he acknowledged the effort, appreciating that Frak was trying to act like an adult.
Reginald set off in search of the Mutation Monster. However, the creature ambushed him, and when Reginald attempted to use the net launcher, it initially seemed effective, but the monster broke free. Just as the monster was about to strike, Frak and the rest of the ninja arrived to save Reginald. The Mutation Monster relentlessly attacked Riyu, poisoning him in the process, until Sora managed to trap the creature in a cage. Despite recognizing that Frak had acted to save him, Reginald chastised his son, believing that he could have captured the monster if Frak had not intervened. He advised Frak to think more carefully in the future, but Frak was focused on Riyu.
A Wonder of the Merged Lands[]
When Frak and Sora went to the Expanding Frontier to get some energy from the Mutation Monster, they saw the Explorer's Club celebrating their mission's success, including Reginald. As Rowan gave him a cake, Reginald gave speech to the other members, saying that they defeated a monster and saved an innocent town. However, Sora countered that by saying Riyu did that, which Reginald acknowledged but said they were the one who actually captured the monster. Sora countered again, saying that she was the one who containtment unit, which Reginald said she did an excellent job obeying him. Then, he announced that they will transport the creature to Ninjago to display, which the other members cheered. When Sora put the device on the containtment unit to collect monster's energy, Reginald said that's the property of the Explorer's Club and they are not allowed to touch it. However, Frak said the energy could save Riyu's life, which made Reginald try to charge them. Thankfully, Sora collected the energy when he was about to do that. As they went back to the windmill, Reginald said they were only able to do that because he gave them permission,
Seed and Soil[]
After the Mutation Monster escapes, Reginald finds Frak and Sora and gets angry at them for letting the monster escape, asking what kind of ninja are they and saying that monster is his valuable property. As the two leaves to catch the Mutation Monster, Reginald tells them to bring to monster back or they'll have the Explorer's Club of Ninjago to answer to.
Just Under the Surface[]
After the Mutation Monster's disappearances, Reginald comes out from the Expanding Frontier, accompanied by Johnny and Rowan. He said that there is no point of staying in Umbrasilvis anymore, since Riyu destroyed their specimen. However, they were stopped by the Grand Inquisitor, who said nothing comes good from outsiders. Reginald countered his words by saying they would be discovered if it weren't for them. Then, the Grand Inquisitor announced that Umbrasilvis is in lockdown until the one who released the monster is punished, which made the Umbrasilvans cheer, much to Reginald and other's confusion.
The Grand Inquisition[]
Reginald testified in court at the request of the Grand Inquisitor, explaining that the Explorer's Club logbook confirmed all members were present the previous night, indicating they could not have released the Mutation Monster. However, Reginald pointed out that the logbook did not include the ninja's names, casting suspicion on Sora and Frak. When the Grand Inquisitor inquired whether Reginald could vouch for the two, he declined, which upset Frak. The tension escalated when the Grand Inquisitor pressed Sora and Frak about their absence in the book, leading to Frak dismissively labeling the logbook as "stupid." This remark offended Reginald, who shook his head in disappointment at the lack of respect for the book. During the recess that followed, Reginald remained with the Explorer's Club while Frak and Sora searched for the real culprit, with Frak suspecting Reginald might be the Loyalist since he could not defend his own son.
After a while, the Loyalist approached the Tree of Burdens to retrieve the red fragment of the Weapon of Desolation. Reginald overheard Frak accusing the Loyalist of being him. When the Loyalist attacked Frak and Sora, Reginald intervened, defending Frak by pinning down the Loyalist. Reginald unmasked the Loyalist and discovered it was Johnny, feeling betrayed by a member of the Explorer's Club. Frak attempted to pick up the red fragment but lost control of his powers. Reginald reassured him, reaching out for the fragment and urging him to let go. Frak handed it over, and Reginald carefully wrapped it in an enchanted handkerchief. However, he hesitated to pass it to Sora, embarrassed by his uncertainty in handling rare artifacts. Frak thanked Reginald, but the latter was taken aback to learn that Frak viewed him as a villain, a perception rooted in Reginald's absence during crucial moments in Frak's life. Reginald explained that he wanted to be a father his son could be proud of, explaining the challenges Serpentine used to face in Ninjago. However, Frak countered that Reginald never tried be a good father. Stunned and filled with shame, Reginald reached out to Frak, but the latter pushed him away, leaving with Sora to turn Johnny in.

Apperance
Personality
Personality[]
Just like most of the members of the Explorer's Club, Reginald carries an air of vanity mixed with composure, while also putting his professional accomplishments over anything, even his personal connections, like his own son, Frak. He can also be very condescending and somewhat of a bully to the less accomplished members of his group, as seen with his interactions with his fellow member Gweeg. He is also very adamant to the rules of the club, like using logs for any member of the club that enters the airship or the naming rights for the one that captures a non-discovered creature to the point of risking his and his group's safety.
This uptight and condescending posture is also showed on his own relationship with his son. Not only he prioritized his career over spending time with Frak, leading him to miss many of his important childhood moments, but, whenever they are together, Reginald is showed being controling and a perfectionist towards his son. Not only that, but his condescending attitude causes him to dismiss Frak's ideas and make him feel like he is not good enough, even if this appears to be not intentional from Reginald's part. When Frak was put on trial for being suspected of being connected with the Mutation Monster, Reginald was more concerned in liberating himself and his fellow explorers out of suspition and didn't do any effort to do the same for Frak.
After a heart-to-heart with his son after saving him twice, where Reginald discovered Frak suspected him of being the one responsible for releasing the captured Mutation Monster in order to find a mysterious artifact, the former reveals that his motivation to become a well-respected explorer was so he could build a legacy that would make Frak proud of him as a father. However, due to the pre-existing prejudice against Serpentine, Reginald was forced to work twice as hard and twice as long to prove his worth and gain the recognition he now has. Upon hearing Frak venting how he felt he failed him as a father, Reginald appears to get filled with shame for his actions towards his son. However, despite wanting to reach out to him and try to apologize, Frak simply couldn't forgive him for choosing to be an explorer instead of a father to him and left on bad terms.

Trivia
Trivia[]
- In "Cursed!," he is referred to as "Dr. Dr. Reginald Slitherbottom," reflecting his two doctorates.
- He is the second parent of one of the ninja to also be a member of the Explorer's Club at some point, the first being Misako.
- Interestingly, both were absent during their respective child's childhood, albeit for different reasons: while Misako left so she could find a way to prevent her husband and son from fighting each other, Reginald missed part of Frak's childhood because of his desire to become a well-respected explorer.
- Additionally, while Lloyd came to forgive Misako, Frak didn't do the same for his father and is currently on non-speaking terms (from his part) with him.
- Interestingly, both were absent during their respective child's childhood, albeit for different reasons: while Misako left so she could find a way to prevent her husband and son from fighting each other, Reginald missed part of Frak's childhood because of his desire to become a well-respected explorer.
- According to Chris "Doc" Wyatt, Reginald is a Constrictai.[1] However, he has a very different appearance compared to the rest of his tribe, being the only one with pink eyes instead of yellow and long legs.
- Like his son and his mate, he more so resembles a snake warrior.
- Based on the photo Frak has of his parents, it seems to suggest that he along with his father and mother once lived in the Tomb of the Stone Army, since the background and ground match what was seen in "The Curse of the Golden Master."
- Considering how most of the members of the Explorer's Club appear to be snobish and condescending and the fact Reginald had to work even harder to earn some respect from his fellow explorers, it's possible that he mirrored their attitudes, eventually projecting them towards his son. This would explain the tremendous contrast of the way Reginald treated Frak, especially in front of his fellow explorers, while still showing that he still loved and cared his son very much, as showed when he saved him from his overpowered elemental power.
