Crono

Crono (クロノ, Kurono: Chrono) is the spiky-haired protagonist of the game Chrono Trigger from the Chrono series. He is a playable character in both Super Smash Flash and Super Smash Flash 2.

In Super Smash Flash
Crono appeared in Super Smash Flash without much speculation as an unlockable character. He could be available by clearing 3-Minute Melee with any character.

In Super Smash Flash 2
Crono was previously confirmed to return as the only character representation of the Chrono universe. He is currently the most incomplete character due to the fact that absolutely nothing is known about him, including his sprite sheet
