Fred is an ally in Kingdom Hearts III.
Fred has a comic geek side that knows a lot about superheroes from their comics. He basically wanna be a superhero like them. When wearing the suit, he feels like a superhero on the outside, but full of excitement on the inside.
When Fred's wearing his suit, it's more of a monster design with the blue and orange color scale, three eyes (two in the middle, one on top), claws, and a tail.
Fred and the rest of Big Hero 6 appear in their hometown of San Fransokyo in the game, first attempting to fight the Heartless on the San Fransokyo Bridge before being aided by Sora, Donald, and Goofy. However, when Hiro discovers a news article online calling doubt into Big Hero 6 and their ability to protect the city, Fred admits that while they still put an effort into fighting the Heartless, Honey reminds him they still got their butts kicked. He is then formally introduced to Sora, Donald, and Goofy, showing that his monster appearance is just a costume by taking the top off, which causes Sora to nearly spill the beans that he's not from San Fransokyo before Donald and Goofy silence him. After Sora explains what the Heartless are and what they are attracted to, Fred sees it as the classic battle between light and darkness before Wasabi reminds him of the severity of the situation since Big Hero 6 has no real way of fighting the Heartless themselves compared to how more experienced Sora, Donald, and Goofy are due to having fought them for some time now. When Sora is put through various simulations to help Big Hero 6 fight the Heartless, it inspired Fred in giving his suit the ability to also breathe ice alongside its fire-breathing power.
Fred and the rest of Big Hero 6 than support Sora, Donald, and Goofy with fighting the Heartless, as well as combining his new ice ability with his original fire ability as a combo move, until they discover that the Baymax left behind in the Silent Sparrow portal when they defeated Professor Callaghan and rescued his daughter Abigail has been corrupted by the Heartless with the surviving Microbots and turned into a mindless creature of destruction. Working together with Sora, Fred and the rest of Big Hero 6 are able to defeat the old Baymax and purge the Heartless corruption from him, restoring him to normal. With two Baymax at their side now, Big Hero 6 continues to protect San Fransokyo from danger.
Fred is a main character in the Disney film Big Hero 6.
