Flex Faptor

Flex Faptor is Speevil Underwood 's first challenger in The Winter Olympics 2019 King of Games Festival of Rio De Janeiro. He is Rex Raptor 's cousin who has a compulsive hobby of, well...fapping. Rex taught him to be a dino duelist in hopes of finding him a more socially acceptable pasttime, but it has done little to dissuade him from falling back into old habits.

Design
Flex's VR Chat model appears to be a mash-up of Jaden Yuki, Yami Yugi, and a female Obelisk Blue Duelist Academy student. As such, he looks to be a brown-eyed young man with a sizable pair of breasts. While this is acknowledged by the other characters in the episode, it is unknown at this time if this is an official fixture of his character or a model oversight. His outfit consists of a pair of jeans, multiple belts, ankle boots, and a sleeveless Obelisk Blue uniform top. However, in chapter 2 of the Speevil fan manga, it is revealed that he was cross-dressing, presumably with the female Obelisk Blue top, which was grounds for his expulsion.

Voice and Mannerisms
Flex has a gruff, loud voice similar to Rex Raptor's and, like his cousin, uses a reptile-heavy deck, consisting of dinosaurs and dragons.

Despite having a well-structured deck, however, he is not a very good duelist and makes glaring mistakes (such as mistakenly tributing Sabersaurus for the weaker Meteor Dragon or equipping Raise Body Heat to Masked Dragon, a Dragon monster which cannot benefit from that equip spell).

He is incredibly hormonal, and is aroused by anything that can vaguely be construed as sexual. Unfortunately, this fixation often lands on his monsters and opponents, leading to him losing sight of duels in favor of relieving his tension.

Biography
We first meet Flex in round one of The Winter Olympics 2019 King of Games Festival of Rio De Janeiro where he introduces himself as Rex's brother, an otaku weeaboo who is out to claim the title of King of Games. After Yami Yugi reminds him that Rex doesn't have a brother, a three-way duel against Yugi and Speevil begins.

As the duel progresses, Flex unsuccessfully hits on Dark Magician, Dark Magician Girl, and Speevil before becoming distracted by discovering the Little D card in his deck, accusing Yugi of putting it there. A few turns later, he uses Adhesion Trap Hole on Speevil's Perfectly Ultimate Great Moth to defend himself, unintentionally ruining Speevil's play against Yugi, as the Moth was now too weak to destroy Dark Magician. As the two argue, Flex reveals that he has seen Speevil's youtube videos but refuses to subscribe, angering Speevil anew and leading him to destroy Flex's Little D.

Yugi initiates a truce with Flex by using his next turn to attack Speevil in the name of Flex's Little D, which Flex tearfully appreciates. As Yugi vocally puts his faith in the Heart of the Cards, Flex counters by calling upon Grandpa Muto. When questioned, Flex explains that he sometimes goes to Grandpa's house to "relieve his pains".

Eventually, Flex & Yugi gang up on Speevil and defeat him, with Flex then destroying all of Yugi's monsters and his own Meteor Dragon with Tyrant Dragon through the use of the Traps Burst Breath and Michizure, though he still winds up losing the three-way to Yugi in the end. We last see him attempting to chase down Speevil for a defeat touching hug before he is, apparently, jailed for indecent exposure in a Walmart.

Later on, while he was reading "How to stop fapping for dummies", Flex finds Speevil sulking in his library, depressed over the fact that he lost the tournament and the chance to save his brother (twice) and was also rejected from culinary school for burning water, the latter incident enraging Flex, as he was the one whom gave Speevil the money to go to culinary school in the first place, but now Speevil can no longer pay him back, and physically assaults him. Flex then gives Speevil an ultimatum: either pay him back all the money he owes ($50,000) in 24 hours, or duel him in a Shadow Game so Flex can take his soul and sell it to the Shadow Realm, as well as sell Speevil's organs, to make back that money himself. Speevil accepts the duel, knowing full well he could never make $50,000 in a single day, under the condition that Speevil could stay at Flex's place for another month rent-free if he won. Flex started the duel strong with powerful Dinosaurs in Uraby and Sabersaurus, but Speevil countered with a deceptively strong Arsenal Bug, while using Bladefly to keep Flex's Dinosaurs weak. Flex then attempted to turn the duel around using his Little D with The Seal of Orichalcos, but Speevil simply activated his own Seal of Orichalcos, and destroyed Little D with Petit Moth, before using it to finish Flex off. However, Speevil agrees not to take Flex's soul, in exchange for Flex also giving him a one-month extension on his $50,000 payment.

Deck
Like his cousin, Rex Raptor, Flex employs a Dinosaur Deck, revolving around aggro tactics with dragon type monsters once again being his strongest cards, but he also has a few Red-Eyes support cards as well (though he is never actually seen using Red-Eyes Black Dragon). However, due to his Deck's offensive nature, he has difficultly recovering from counter-attacks, and thus must ensure that he has the stronger monsters on the field.
