I am still fond of the ultimate showdown, even though it is very old now
link;
http://www.ultimateshowdown.org/There is also a parody of it at newgrounds, but I am afraid is it so vulgar that I have to warn you all before going there;
DONT CLICK ON THIS LINK IF YOU ARE UNDER 100 YEARD OLD, OR UNLESS YOU REALLY, REALLY WANT TOO. YOU HAVE BEEN WARNED!!!?!
EDIT; I removed the link, on seccond though it's not a good idea
Enjoy, or probibly not.
