I would like to see some deaths be permanent. Super-heroes should be like job positions. When a vacancy is open, other people can apply to take over that positions. Wouldn't it be cool if heroes switched their characters?
I'm really looking forward to seeing how this Alpha character turns out. I'm kind of hoping that it doesn't just end up with the cliché arc of protege is too greedy/impatient and eventually turns on master (i.e. Rocky V).
