Trilo-Beast Zazanyoda is a monster in B-Fighter Kabuto. Born from a Trilobite fossil, he was sent to abduct the girls at Kouhei Toba's school and to absorb the lifeforce from people through his extending tentacles and use it to enlarge himself to giant size. Zazanyoda was almost invincible until the B-Fighters fired at his weak point, the small trilobite on his forehead. Reduced to his normal size, he was killed by the B-Fighters.
