Something I just noticed: This drawing of the Mega Man 8 intro boss which I think is official (but I'm not sure. I hope so or this toot is a bit pointless.) has it giving the bras d'honneur. Which is:

-odd.
-rather surprising given the series.
-probably the reason Dr. Wily gave his crab robot pincer arms in the first place, in stead of something sensible like rocket launchers.
