Expansion character

An expansion character, also known simply as expansion or extra, is a playable character that is not available in Super Smash Flash 2 roster as a normal character (those who are starter or unlockable) but could be downloaded into the game making the roster bigger everyday. With this concept, many characters that didn't get into the SSF2 roster, may be added to the content of many people. Once downloaded, the expansion may be playable on every game mode in SSF2. Besides downloading the character, one also acquires extra trophies for said character by clearing the Classic Mode, Adventure Mode and All-Star Mode, it should be noted that the trophy's stand for expansions is gray rather than the normal brown.

There is a strict any and all policy on who can be expansions. If anyone wishes to make his own expansion character, whether it is a fan character, a favorite video game character, or just a fan or original character, will have to go to the Super Smash Flash 2 Expansions Forums and show the animated sprites, moveset concept and many other stuff so it could be judged and qualified by the Expansion Acceptation Team (EAT for short). Despite this, it has been confirmed that if online matches are possible, only expansions made by the SSF2 Devs (thereby known as Official Expansions) would be playable.
