Whose PC is that Hero?

We (bateleur, floralaetifica and I) got about two-thirds of the way through Heroes season 2 last night when bateleur announced "He's a dr_bob character isn't he!". We agreed and proceeded to play the match Heroes (primarily those also in season 1) to players game.

( Match-ups based on information from almost all of season 2 - major spoilers for season 2 )

A review of the season to follow just as soon as I've finished watching it. I may even still do a season one episode-by-episode review as well.
