So in Brotherhood it was pretty clear that Pride and Wrath were #1 and #2. Pride was in a league of his own really.
But what about the 2003 anime?
Notable differences between Anime and Manga Homunculi:
-Bradley is Pride and has standard Homunculi regen as well as blur-speed
-Sloth is made of water
-Wrath is a kid who can use alchemy and merge his body with any substance
-Envy has no "monster" form but he's also a much better fighter in the anime and he's the oldest Homunculus
-Lust and Gluttony are pretty much the same only Gluttony lacks the false gate
-Greed only has his original powers and is not Greed-Ling. He was the second oldest Homunculus in the anime though.
So how would you rank 'em from strongest to weakest?
