The rules are simple. Peter and Sylar have all the abilities that they mimicked or replicated in the show. Peter can use any power that he's been exposed to. However, he can't mimick Superman. But Sylar can use ineptive aptitude to see how Superman works.
Ando won't be participating in the battle as he would probably be the firs one killed. He is only here for the purpose of using his power to enhance the abilities of Peter and Sylar. However he can be harmed. And he also has to be within a 500 Yard proximity to be able to use his ability. If push comes to shove then he'll come into the battle, but honestly, I don't see what he can do.
If I'm missing any abilities for either Peter or Sylar, don't be afraid to tell me. I'll add them to the list. No Bfr.
Pre flash point superman. Aside from that, I don't see what I have to explain. This is your standard heat vision superman.
Peter and Sylar have recently discovered a person with uncontrolled induced radioactivity powers in the area. They believe that if unkempt, he might destroy Smallville and two surrounding cities. Though the blow won't be as powerful as Peter's radioactivity being able to destroy New York. They decide to go and contain him and teach him how to use his powers. Superman finds them and believes them to be working with Lex Luthor and trying to abduct for superhuman experimentation. A fight ensues.
