Steve

Steve(full name Steven Torrence) is one of the few human protagonist along with Andre, Kyle, Anthony and Will. He makes his debut in chapter 3 working as a bouncer for Kyle's party. For some reason Steve has the ability to return in future episodes even though his life comes to an unfortunate end, the reason behind this is unknown.

Taking over
In chapter 3 Steve was shown working as a bouncer for the party Kyle was throwing at Peach castle. He checks Play's I.D and talks with Andre when he walks up to him, he lets him pass along with Play. Sometime later that night Steve was seen guarding the entrance to the castle from Sonic the Hedgehog stating Kyle "said no" and that he wasn't allowed in (possibly due to the fact that Kyle's a Mario fan and Mario fans usually have a dislike toward their rival Sonic the Hegdehog) but Sonic gets angry and kills Steve by spindashing on his face.

About a few minutes later when Anthony and Will arrived at the castle, somehow, Steve was there to check to see if they were on the party's list or if they had I.D (note: Anthony asked if Steve died in the previous but Steve didn't reply as if Anthony never asked) when Steve didn't allow them in Steve was shot in the head by Will allowing Anthony and Will to pass.
