didn't you pay attention? they're only bringing in the powers that were forced upon those, not ones they were born with etc. Superman, Green Lantern (it's been hinted Hal Jordan might appear this season, but not as G.L) etc.

if they bought superpowers into Arrow, that would destroy the show, that's why they bought in Barry Allen, to see how the audience took it.
