Fan character

I SAID STOP

Blue
Blue is a character created by user topcat13, for the sole reason of appearing in Super Smash Flash. Like Blade, this character derivates from Flare the Hedgehog. Blue's sword emits fire.

Robo Ninja
Robo Ninja, also formatted as Robo-Ninja, is a character created by the McLeodGaming Forums member Raccoon. Little is known about this character, other than that she is a robotic female character who carries a large metallic Bō staff.

Robo Ninja was initially planned to appear as a playable character in Super Smash Flash 2. No information is known about what her moveset would have included or how she would have appeared in-game. Unlike other fan characters, she was removed from the roster very early into the game's development. This was at the request of her creator as he wanted to use her in his own projects instead, but she has yet to be seen again on her own since then.

Spikeman
Spikeman is a character created by the McLeodGaming Forums member of the same name. He is a red ball with shoes and a red mane who commonly uses his tongue to attack or grab, due to him having no arms. Nothing else is known about him or his origins.

Spikeman was initially planned to appear as a playable character in Super Smash Flash 2. The only element of his moveset to be officially confirmed was that his Final Smash would have had him turn into Insane Spikeman, a Transformation Final Smash that would have made him smaller, faster, and stronger with a completely different moveset. Like with most other fan characters, he was removed from the roster following its revamp. Unlike with the other fan characters, however, it has been confirmed by developers that Spikeman will not return as an expansion character.
