Especially when the character is so obviously broken, like Dark and Shadow Donald. Cheap characters with badly animated move sets, who don't fit in with the rest of the roster, either in look, story, or gameplay - that's the essence of MUGEN.

It's a lot more interesting when observed from a distance.

My favorite constant in this one might be the "DON DON LUU" rendition of Sabre Dance.

Since his Japanese name is Donald that makes sense.
I'd thought until now he was just yelling RAN NAN RUUU!!

MUGEN is only like this if you make it like this.

This was the reason why I downloaded Mugen:

Haven't seen anything that compares.

MUGEN is so great because of OP characters like this. There's a Homer floating around somewhere that is unbeatable. If either player is taking it seriously, the match is forfeit.

Full Disclosure: This Ronald is my favorite character, purely for the closeups. Also the aforementioned Homer, and the Killer Whale.
