Unfortunately, this is probably my least favorite of the series so far. Hunter had a kick-ass design, but there were two big things that killed it for me:
1.) The whole thing felt like a poor attempt to mimic the ol' X-Men "fantastic racism" scenario, but it just doesn't fit in a setting where everyone is infected (this was mentioned very briefly, but shrugged off too quickly, like the writers would rather be doing an X-Men story).
2.) The "rival hero creates his own disasters to stop" thing, as I mentioned in the UA "Hero Time" thread, is one of my least favorite cliches. The moral ambiguity with Hunter was the only good thing about this episode, but then it just gets thrown away and we get "Nope, he's full-blown bad guy!"
