I will have to do a bit of digging but all I know is that he controls AcroBatter with "RX's Telepathy" (the bike also uses this to home in on his location.) I'm guessing that since his antennae and the â€Psycho-Indicator" (the round jewel on his head) are blinking, they're having some kind of telepathic thing going on (I'm just guessing, but when Rider 1, 2 & V3 did the telepathy thing they'd focus on their antennae and the O-Signal usually.) I'll have to see if I ever come across any proper names for it.
