Battle of the 99 Heartless?

Battle of the 99 Heartless? is event #21 in Super Smash Flash 2.

Overview
Playing as, the player must KO a total of 99 es on Twilight Town within a time limit of 5:00. The player has 2 stocks, and each Mr. Game & Watch has only 1 stock. Up to four opponents can appear at once and defeating one will cause the next one to appear. Normal, giant, tiny, and metallic variants of Mr. Game & Watch will appear, and they all have a damage ratio of 3.5, making them easier to KO.

Rankings
The ranking the player receives is based on how much time the event takes to be completed. The specific conditions for this are listed below.

Trivia

 * Clearing this event will unlock The World That Never Was.
 * Prior to Beta 1.0.1, Sora only had one stock in this event. This was changed to two stocks to make the event easier.
 * Additionally, the opponents dealt normal knockback to Sora, but Beta 1.0.1 changed that; he now takes less knockback from attacks in this event.
 * This event is based on "The Battle of the 1000 Heartless", a story event in KINGDOM HEARTS II where Sora, alone, has to defeat 1,000 Heartless who are attacking the world of Hollow Bastion.
 * The metallic variants of Mr. Game & Watch may be a reference to Nobodies, which are often white and gray as opposed to the purple and black Heartless.
 * This is the only point in SSF2 where more than four characters' huds are onscreen at once. Sandbag Soccer, Sandbag Basketball, Multi-Man Smash, and Ditto may also load a fifth character, but they are not counted by the game as separate combatants in those cases.
