Atchpetchy is a cactus-like alien with jaw-like pincers sent by Gedorian without Jark's consent to turn the Sahara family in cacti-slaves that attack RX until he is forced to fall back when the effects wear off. But Maribaron offers her aid to Gedorian by tricking a girl named Chika into giving up her life to Atechpetchy so his power can be perfected. But RX ruins the scheme and destroys Atchpetchy with his Revolcane.
