The funniest thing with megas is you get all the Vicious Behaviors and such but then you also have goofy things like
Mega Pinsir: After Mega Evolution, it becomes able to fly. Perhaps because it's so happy, it rarely touches the ground.
Kangaskhan: Mega Kangaskhan's strength derives from the mother's happiness about her child's growth. Watching it grow up keeps her spirits high.
(all of Kangaskhan's are funny actually because even the "dour" ones are like "Mom worries about her growing up child")
Slowbro: Having been swallowed whole by Shellder, Slowbro now has an iron defense. It's pretty comfortable in there, too.
