You know.
Mine is (surprizingly) classic 8-bit Mega Man sprite: He runs, he shoots, he blinks his eyes while at it, AND he changes his expression (while e.g. jumping). That is a really advanced sprite for a 8-bit machine, and one of the most impressive sprites I`ve ever seen, for the day`s standards anyway!
You got an absolute sprite-favourite? Tell us! ^_^ But be sure to explain why!
Everything from Atari to PS2 (aka this gen) counts!
Mine is Sakura dancing after she wins from street fighter alpha2/3.
I think shes a cute character and when she dances it just sends cuteness waves all around.
Just look at her!

I love Rose's perfect win pose. I love it because I love the dress she changes into. I like the use of the Fool Card (and, of course, the reinforcement of Street Fighter Zero).
This version of the file is different that 99% of the versions found on the Internet. If you can figure out what it is, I'll give you applause.
Zabel's "I'm living and your dead" from Vampire Hunter. I can never find that damn thing.
