100-Man Smash

In Super Smash Flash
This mode was originally called 100-Man Melee, as it was called in . As with other Multi-Man Melee modes, 100-Man Melee is always played on and the opponents are always the Fighting Silhouette Team. It is a more advanced version of 10-Man Melee and usually takes a few minutes for players to defeat. Unlike , there are no checkpoints in 100-Man Melee after defeating a certain number of opponents, they are always at the same level of aggressiveness and the "weight" is the same.

Though opponents are light and more prone to being KO'd, SSF's physics makes them a bit harder to launch them off stage with an single attack other than an up attack or a projectile. Additionanlly, some opponents have access to different moves that allows them to recover with ease and shoot projectiles, this considerably increases the challenge.

Rewards

 * Completing 100-Man Melee with any character will challenge the player to fight, where victory will result in unlocking the character.

In Super Smash Flash 2
This mode is now known under its current name of 100-Man Smash, as it was called in. Much like its predecessor, battles always take place on against the Fighting Silhouette Team, who are still light and more prone being KO'd. SSF2 features improved physics, which eases the game mode a lot as the Silhouettes now have a limited moveset, which now prevents them from using special moves, hindering their recoveries. Once again, no checkpoints are present, the aggressiveness and weight remains the same throughout the mode.
