Dorcus (ドークス), known in English as Roks, is a stag beetle-type Medarot that first appeared in Medarot 3 and is an upgrade to Rokusho. Dorcus also appears as a character in Medarot Damashii, but with no relation to Rokusho. His name was taken from the scientific name of Antaeus Giant Stag Beetle (Dorcus anteaus)
Dorcus is a Medarot similar to a Stag Beetle. Being a KWG-type, it is mostly focused on grappling and scanning techniques, which makes it suitable to wear grapple-based medals, specially the Kuwagata one. However, his medachange form allows it to also shoot both antiair and antisea missiles to its opponents, and it can also move effectively in rough terrains.
 In the games
Note: In Medarot 3 and 4 stats, including Medachange, a stat listed as a / b (for example 1 / 2) means that the stat a belongs to Medarot 3, while the stat b belongs to Medarot 4.
 In Medarot 3
Ikki Tenryou appears with Rokusho as his Medarot prior to the Kuwagata version of the game, but soon he replaces his parts with Dorcus's ones, which enable him to perform a Medachange.
 In Medarot 4
Its model number is now KWG-5.
Dorcus appears as Ikki's first Medabot in the Kuwagata version, already upgraded from Rokusho.

 In the anime
Dorcus is a Medarot who is dedicated to destroy Death Medarots. His Medarotter, Yuuzuru, only fights with Dorcus when disguised as the Mystery Medarotter. At one point Yuuzuru replaces Dorcus for the Death Medarot Excize, but Ikki convinces him to take Dorcus back.
