I like that Tim's series is all about him globetrotting all on his own, all over the world with nary a soul to help him...and then there's all these crossovers where someone with superpowers zooms over and is all "hey help me out, man", and he's all "dang it, ok" and then they fly back to the states, solve some mysteries, fight some crime, and then they fly Tim back to wherever so he can brood.
