Fratellis (Furaterisu, also called Fretellus) is the android serving Gilliam.
He is noticeably muscular and has a visor covering his eyes, which oddly have three visual sensors instead of two. Like Francisca, he has a fighting ability programmed into him and like all androids, he can't attack Royalties and can only say "fuga." He is dressed like a butler.
In Princess Super Express, he tried to throw Gilliam's particle cannon at Emile's train cart, only for Emile to send it right back, destroying him.
Mark II[]
After Fratellis was destroyed, Gilliam stole an android named Mark II from the Professor. Mark II is identical to Fratellis except slimmer in build, has a slightly different hair style and lighter skin. During Gilliam's battle with Fuhito, Gilliam trapped Fuhito in a small chamber underground and used Mark II to weigh down the cover. Fuhito super-charged his telekinesis and blew right through Mark II, taking off his right side.
