Colossus Bat

"Yay! Shall we go?"

- Colossus Bat's first quotes

The Colossus Bat is the transformation device & partner to Kamen Rider Colossus. The Colossus Bat is a mechanical Vampire Bat created by the Legendorga for their leader to assume his rider form. When Kamen Rider Colossus uses the Wake Up Fuestle (which resembles Blizzard's Key Fuestle), Kamen Rider Colossus transforms to Legend Colossus & the Colossus Bat also assumes Mecha Bat mode as his persona cast comes off & yells, "Die."

Personality
In the short amount of time he was seen talking, the Colossus Bat is cheerfully sadistic, taking delight in destroying Colossus's enemies.
