"It's more than a little annoying that we got a concept art figure before we got more of the Deadpool Corps, but whatever. Infinite multiverse, infinite possibilities. Maybe this is from a universe where the 90s never ended?"
The "Deadliest Foes" pair also includes a chunk of the Ultimate Green Goblin BAF that everyone in this series teams up to build. Specifically, the left leg, twin to the piece included with Superior Spider-Man, and still just a reworking of Hulk's.
It's annoying that we still don't have a normal Beetle, but nobody has ever made a Boomerang toy before, so that at least is exciting - and it's not like Ultimate Beetle is bad, just... not ideal. Not 616. We can't hold that against him, can we? If you don't want to buy both these figures, either one is a fine option.
