The X-Men Family Tree.
And you know you're a true comic nerd when you look at that, can identify every character, and can name a few dozen others that could fit in there.
Cool image, though. Very inspiring.
I understood a lot of that...
Oh... there's only 4 of them I can't identify... I didn't know deathbird had a kid and I can't recognize the two who are at the right of Sabertooth and Graydon Greed.
Also, is the Wolverine Clone with red eyes X-23?
