Yusei Fudo is the main protagonist in Yu-Gi-Oh! 5Ds. However, Yusei has the unfortunate fate of being the least featured of the 3 main Yu-Gi-Oh! protagonists in Super Smash Bros. Crossover. Yusei first appeared in Season 11 along with Yami Yugi and Jaden Yuki to help the Heroes of Legend in the battle against Reiaz. Yusei doesn't appear in Season 14, but Yugi Muto stated he was with Jaden at the time. Yami Bakura considered kidnapping a close friend of Yusei's, but decided not to as he barely knew anything about Yusei and Yami Bakura didn't have a motorcycle on him, referring to Turbo Duels. Yusei eventually reappears to duel against Yami Bakura. Yusei reappears after another absence to support the Heroes of Legend in the final battle against Samus Aran and Yami Bakura. In Season 19, Yusei is now a main member of the cast. Yusei goes into the Shadow Realm along with Yugi, Jaden, and Naruto Uzumaki to find Sasuke Uchiha, who had betrayed the Heroes of Legend. Yusei takes responsibility of carrying the unconscious Zombie Wasp on his back.
Yusei's appearance is based off his appearance in Yu-Gi-Oh! 5Ds.
Yusei is calm and stoic, and never gets reckless in a duel. He also cares deeply for his friends, as he stood up to Yami Bakura to stop his plans in order to protect his friends.
