The Universo Project's Imra is probably my favourite Imra ever, with reboot Imra from Legion Lost being a close second.
I'm patiently waiting for JL vs LOSH to conclude and see if there's any more Legion coming from DC but I'm not very hopeful. I think they've maxed out the number of reboots the property can withstand, to the point where it's all a bit of a joke now. But most troublesome, not even the high-profile creative team of Bendis and Sook could sell the book in any decent numbers. I don't really know where DC could go from there, unless a really big name like Johns or Hickman comes in I don't really think we'll see the Legion in their ongoing book again anytime soon.
