Blackbeetle is a female beetle-type Medarot modeled after Saikachis, with the most notable differences being black colouring and a metallic eyepatch over its left eye. Compared to Saikachis, Blackbeetle's parts are more focused on power than speed. It also has the ability to Medachange into a tank-like Medarot, sacrificing speed for attack power. Like most KBT-type Medarots, Blackbeetle is exclusive to the Kabuto versions of the games, with it's KWG-type equivalent being Blackstag.
Blackbeetle's model number is technically the same as Saikachis (KBT-5), but with its parts numbers starting at KBT-55 to KBT-59. Due to other KBT-types not appearing, it is given the number KBT-35 in the game Medarot 3.

 In the anime
Blackbeetle appears late in Medarot Damashii as a Death Medarot used by Kokuryuu. She is one of the few Death Medarots with a Death Medal (known as a Neo-EX Medal in english versions) which allows her to think and have feelings unlike other Death Medarots. While she is very loyal to Kokuryuu, she becomes afraid of him near the end of the series when he decides to use her medal in the extremely powerful Death Medarot, Grain. Eventually she is unable to control Grain and goes berserk, but is rescued by Ikki and his friends. In the end, she stays with Kokuryuu after he is defeated, with him finally realizing the importance of Medarots as friends.
