Blue (when using power)
All's well that ends well
Travis Willingham (English)
Antonio is tough and usually confident. However, he is often bothered by the fact that he is last in the rankings and by his declining popularity. He is often the butt of jokes as a result. He tends to be stubborn, but is caring and very loyal. He enjoys bragging about his power and does whatever he can to earn a name for himself. At one point he becomes so worried and desperate he copied his fellow heroes' schticks.
Little is known about Antonio's past prior to the series.
The First Hero Tag-Team
Jake Martinez and a City Held Captive
Antonio has known Kotetsu since high school and the two are very close. Antonio heard rumors that Kotetsu was very strong, so sought him out to challenge him to a fight to see who is stronger. Not interested in fighting him, Kotetsu tried to avoid Antonio until a member of Antonio's gang kidnapped Tomoe. When Antonio found out about the kidnapping he teamed up with Kotetsu to rescue Tomoe, and the two became best friends soon after.
Occasionally they will argue and decide to finish the fight to see who is stronger, declaring that whoever wins will be the winner of the argument as well. However, something always interrupts them before they can finish and determine a winner.
When Kotetsu has problems, he occasionally goes to Antonio for advice. When half the heroes were sent to the hospital by Jake Martinez, he could tell that Kotetsu was still injured while the others thought he had completely healed with his Hundred Power.
Abilities and Powers
Antonio has the ability to harden his skin, making him impervious to physical attacks. However, even alongside Blue Rose and Sky High, he is unable to stop the ice rink from falling , meaning his strength is limited to some extent.
Rock Bison's costume/armor gives him the appearance of a bull. He is given the nickname "Bull Tank of the West Coast" because of how he charges through enemies using his thick horns or giant drill shoulders. The drills are functional, and he has been shown to use them to navigate slightly in the air after being launched from his transport vehicle.
Like all the Hero TV heroes Antonio wears a simple "communicator" wristband which Agnes can use to contact him, usually to inform him of a crime being committed. The other heroes can also use it to contact him. Antonio's communicator is white with brown bands around the edges.
