Marsha (マーシャ Māsha) and Karsha (カーシャ Kāsha) are the first bio-lifeforms created by Giba, his secretaries and intermediaries between him and his Bionoid agents. They can transform into small bat(Marsha) and spider(Karsha) (for spying on people), and assume their inhuman "Battle" forms (Battle Marsha and Battle Karsha), armed with energy whips. They were killed in the series finale by Doctor Giba for failing to kill Jiban. In the Philippine version of the series, Marsha are Karsha are renamed as Sabrina and Katrina respectively.
