|Berg Katze (Crowds)|
Berg Katse is the main antagonist of Gatchaman Crowds. A mysterious androgynous alien who causes chaos through his shapeshifting abilities and has brought about the destruction of several planets.
Berg had arrived on Earth to wreak havoc on humanity and eventually destroy the planet.
He is also responsible for giving Rui his power to control the CROWDS. As to why he did this or what purpose he intends to use them for remains unknown at this time.
Berg Katse has the ability to shapeshift through direct physical contact (usually by kissing) and an extendable prehensile tail that he uses as a whip. Due to having possession of a NOTE, he can enhance his abilities by activating it. This allows him to extend his tail infinitely to bind, lash or impale his enemies and grants him new powers such as invisibility. His Gatchaman form is presumably so powerful, Pai Pai states that it could potentially defeat the G-Crew.
