Joe is the main protagonist/player character of Oh So Hero!.
Joe is a citizen of Aeter and is currently participating in the Gerrabacco tournament, his intentions with the promised infinite wealth and power reward are never expressed, only telling Ket that he's off to have fun at the tourney before joining it. He has some talent in combat and in some more… intimate ways to get around in the tournament.
His personality is shown mostly through the conversations he has with the NPCs of the game. He's a curious, friendly guy with a happy-go-lucky attitude, trying to appear more serious when he dons his hero costume. He's friends with many NPCs across the game and has the charisma to make many more in his own way.
Joe begins the game with a basic three-punch combo and a Crescent Moon Special attack. But he can also utilize his natural and lewd charms to win over enemies, making them uncontrollably horny and able to defeat them in different ways. He later gains the abilities to slide through tight spaces and ground pound with his bubble butt in a powerful slam.
He's a sky blue dragon-esque anthro who sports a fox-like tail, apparently likes to walk around in tiptoes, and wears what is described to be in-game as a “hero” costume, which consists of a pair of tight black trunks with a red bikini line, black fingerless gloves, and a simple red superhero-like eye mask. He also has a white abdomen, two small wings growing out of his shoulders, and small, nubby black horns growing out of his skull.
Joe appears to have a somewhat elasticated body, able to take abnormally/multiple large insertions and excessive volumes of cum without prior lubrication or stretching. Though, this is just purely to help bypass any annoying aspects of realism that might ruin the more explicit content of the game. It is not completely clear if Joe has scales, fur, or smooth skin.
Transformation (Spoilers)
This section contains spoilers about the finale of Act 1 and the events that happen during its final fight. Only proceed if you've finished Act 1 and seen the victory cutscene in-game.
After defeating Bates in Lood City Park, Bates refuses to take his loss and tries to continue the fight, exerting himself past his limits and releasing chi in a higher amount than he can handle, putting himself at risk. Seeing this, Joe exclaims that he knows what he must do and jumps into the air, transforming into a slimmer, more muscular version of himself.
This version of Joe retains his sky blue skin color with white accents, the black marks going along his arms and neck get more details as well. His eyes gain an amber and blue striped iris with his irises becoming red. In this form however, he loses the details of his body that resemble other animals like his fox-like tail and bovid-like muzzle. Due to this, his appearance is now way closer to that of an actual dragon, even gaining horns and a cape made out of some ink-like energy, the latter replacing his tiny wings. Right after transforming, Joe automatically lost his hero outfit, then recovered it once his transformation ended, meaning he wasn't wearing anything during the transformation.
During the transformation, Joe seems a lot calmer and more relaxed, immediately rushing towards Bates to help with his emotional problems and help him release his chi safely, giving away this form's greater control of it. In the same cutscene, Joe says that he doesn't know “what's up with the new look” and becomes unable to continue lifting Bates after the transformation suddenly ends.
It is unclear whether or not Joe keeps his genitalia during the transformation, as his penis cannot be seen at any point during the transformation. Interestingly, the scene where he helps Bates release his chi has a high angle with a good view of Joe's crotch, in which not only can his penis not be spotted, but instead a line that more closely resembles a vagina can be seen, though it hasn't been confirmed if he does change sex during the transformation.
