Synevite is an advanced Zoanoid that only appears in the Guyver: Bioboosted Armor TV series. He serves as Genzo Makishima's aide at Cronos Japan before Commander-in-chief Richard Guyot arrives to assume control. In the series' third episode "Inspector Lisker", Synevite is dispatched with a team of Zoanoids to capture Sho Fukamachi, the host of the first Guyver unit. After his squad is wiped out by the Guyver's Mega-Smasher, Synevite emerges from Narisawa Lake and attacks Sho. He uses his long, octopus-like tentacles to whip and bind Sho and even squirts a blinding black ink. Because his body is so soft and malleable, Sho's punches have no affect. However, Sho discovers how to use his vibration blade during the battle, slicing off Synevite's tentacles before carving the Zoanoid in half.
Synevite's human identity is known as Kimura, a tall Japanese man with black hair who wears sunglasses and speaks in an upper-class manner.
