Make a Fighter

Make a Fighter is a feature first introduced in Bloodstreams Battles for Nintendo 3DS, which allows players to create their own custom character, and use them on matches. The fighter can be used online or locally.

Bloodstreams Battles for Nintendo 3DS
The Make a Fighter feature in BB3DS was extremely limited, only allowing for fighter names, specials, and, as of the 1.1 update, costumes. Sadly, though, due to the lack of a save system, custom characters would be deleted upon launching again.

Bloodstreams Battles: Zero Hour
Make a Fighter returns to Bloodstreams Battles: Zero Hour with a few retweaks. Nine characters can now be created, but the specials and costume features have been omitted to save space.
 * In Version 1.2, costumes had been restored.

Bloodstreams Battles: Zero Hour Remastered
Make a Fighter in Bloodstreams Battles: Zero Hour Remastered behaves and functions the same as Zero Hour version 1.2.

Bloodstreams Battles Online
Make a Fighter returns once more to Bloodstreams Battles Online with huge upgrades over Zero Hour — costumes can now be defined using URLs, specials can be used for the fighter, the custom character can have their bio displayed on the pause screen, a theme from YouTube embed links can be used for the fighter to play during matches against them and on the Juke Box, and voice clips can now be switched for the fighter. However, the fighter limit was dropped from 9 to 5 due to time constraints.
 * It is also possible to develop alternates for custom fighters.
