Griffin Brock

Griffin Brock (グリフィン・ブロック), self-styled as Granite, is a superhuman criminal and one of the many people infected with Austin Chambers' nanites. At the night of the explosion, Griffin was at a construction site when he was infected with nanites. Now given the ability to turn his skin into a type of granite stronger than any, he faced Hunter Bradley/Arsenal.

Despite not having Hunter's level of skill, Griffin's strength and durability proved to be more than enough for Hunter. Creating clones to overwhelm both Hunter and Lyra Evans, his skin reverted to normal upon receiving an impact from Nathan Schmidt, and was placed into custody.

However, Griffin trained his body and returned a few times to challenge Wes Gates/Stryker, but was defeated a third time, with the help of Geomagnet. Griffin was later recruited into the Brotherhood but was defeated and arrested again.
