Biography
Vexacus wielded a sword and a fan blade, and could summon a giant "land shark". He first comes to Earth hunting an alien who can give her powers to someone when she dies. He fails in his attempt to capture these powers, and ends up stranded when his ship is shot down. On some occasions, he would use monsters that are Phantom Beast-themed.

Vexacus first comes to Earth hunting an alien - a Karminian - who can give her powers to someone when she dies. He fails in his attempt to capture these powers, and ends up stranded when his ship is shot down.

Later Vexacus becomes Lothor's head general, and often clashes with Zurgane. This advances to a point where, after Zurgane's Hyper Zurganezord is destroyed, Vexacus kills him. He later does the same thing to Motodrone, but is stabbed in the back by Marah & Kapri, who arrange for his destruction at the hands of the Thunder Rangers. He returns again after the Abyss is opened, but is quickly defeated (and possibly destroyed) by Shane.
