Ace Barnstormer: martial arts/super reflexes scrapper
My homage to Dieselpunk/1920s-1940s pulp fiction heroes.
There's something very satisfying about the graceful way that scarf moves with the "ballet" that is martial arts.
Major Ray Gunn: energy/energy blaster
my homage to 1930s-1950s sci fi serial heroes
Sea Sentry: staff/electrical brute
There's the matter of the other COH hosted sites as well. I don't know the population counts on them, and I'm guessing Homecoming is by far the dominant one, but with some developing their own power sets and archetypes, there's bound to be at least some bleed-off of players wanting to try every shiny new thing.
