Arcbeetle is a KBT-type Medabot based on a hercules beetle. Arcbeetle appears in the Medabots anime series, where it is the Medabot used by Space Medafighter X.


Arcbeetle is a bright red and yellow KBT-type Medabot with two large horizontal "horns" situated on its chest and head. Like most KBT Medabots, Arcbeetle specializes in shooting attacks, and has guns mounted on both of its arms.

Arcbeetle's name comes from the electric arc that forms between its two horns when it fires its trademark Beam attack.

In the manga

Arcbeetle briefly appears alongside Rintaro in the Medabots manga series released by Viz Media, where he's referred to as Kantaroth. This is a reference to the Japan-only manga Medarot R, where Rintaro obtains Arcbeetle parts as an upgrade for Kantaroth after losing Kantaroth's original parts in a Robattle against Ikki.

In Medabots Infinity

Arcbeetle is unlocked by inserting a Medabots Kabuto Version cartridge in a Game Boy Advance connected through Game Cube Link Cable.


Arcbeetle has a rare card in the Medabots Trading Card Game booster set. Like Metabee and Kantaroth, Arcbeetle attacks with a "Piercing Shooting Attack", which allows it to damage Medabots to the side of the target if the target is destroyed.
