The Decepticons will always have the Autobots outnumbered, since they have the waves of nameless Vehicons. And that is probably how the writers want it, as everything is more heroic if you are outnumbered. That aside though, there seems to be an attempt at least in balance among the named characters. Each corresponds either in type, history, or rivalry with someone on the other side. Optimus - Megatron Leaders, with a history together Ratchet - Soundwave Non-warriors who Can fight when called for Bumblebee - Knockout High speed warriors (most recent episode illustrates) Bulkhead-Breakdown Large brawlers again with a history. Arcee - Airachnid Ninja-like female bots again with a history. Wheeljack - Skyquake Asskickers who stick around for all of one episode. This of course leaves Starscream with no counterpart. It seems like there are at least two directions you could go with this. 1. Give the Autobots some air support and introduce Jetfire, since in some continuities he has had history with Starscream. 2. Introduce Ultra Magnus as he has in at least one continuity tried to overtake Optimus. Of the two I think a Prime Jetfire would make for the best character/figure potential.
