Antonio Lopez is not only a green-armored brute hero but is Wild Tiger's best friend. His bull-themed costume includes advertising for Japanese barbecue restaurant chain Gyu-Kaku.
Antonio has known Kotetsu since high school and is very close with him. He used to be a bully towards Kotetsu, even leading to a fight between them. But somehow they managed to grow together as friends, and fought daily to train one another. When Kotetsu has problems, he occasionally goes to Antonio for advice. When half the heroes were sent to the hospital by Jake, he could tell that Kotetsu was still injured while the others thought he had completely healed with his 100 fold power.
Abilities and Powers Edit
Its not specifically told what his power is, but its most likely superstrength, increased endurance or something that increases his physical ability. Although in the second episode when he along side Blue Rose, Sky High and Wild Tiger tried to stop the skating rink from falling, but even their combined strength couldn't stop. It's most likely his power isn't super strength, as he was unable to lift fallen debris off from a worker in episode 4. This is also explains why even with 3 other heroes besides him he couldn't hold a skating rink from falling, but it could be his powers are limited to some extent. It is also possible that his NEXT ability is to increase his own mass, thus increasing inertia, helping him stop cars with no device, keeps himself in place when normal people woul usually already gone flying, and also lets him travel faster when using the launcher as shown in one of the openings and in episode twoHis suit has two giant drills, which can spin and be used for ramming and drilling through things.
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-head, or giant drill shoulders. Also, his drills are functional, he has used it a couple of times to punch through anything.
- His picture on Kotetsu's phone is that of a bull.
- He and Kotetsu are the only known heroes to have known each other before becoming NEXT heroes.
- There is a similar hero in the manga titled "Ratman"
