The Great One

From Ben10versepedia

The Great One

The Great One is a giant, tick-like alien that travels from world to world, sucking the energy from the planets it lands on to feed itself. This process poisons and eventually makes the worlds it visits implode. Its shell is nearly impenetrable and its feeding process brings the ground to life as an extra defense, making it very difficult to attack. On top of that, it is followed by a group of worshipers that want to make sure that it completes its task. The Great One is destroyed from the inside by Ben as Cannonbolt. The Great One is responsible for the complete destruction of Cannonbolt's home planet about a week before it tried to destroy Earth, a somewhat ironic accomplishment considering its death at the hands of a member of the same species (albeit a spliced version). The Great One and the worshipers all appear in the episode "The Big Tick".

The Great One's Worshippers

The worshipers are three aliens that accompanied the Great One. (In fact, their respective planets were all destroyed by the Great One, and they decided to follow the doctrine "If you can't beat it, join it".) The first is a tall alien, who has a laser/hologram projector on his head and six tentacle legs. The second is a medium-sized alien with four eyes and a large battle axe, which can also fires lasers when swung. The third is a short six-armed alien with a laser on his forehead. The latter of the three can communicate with the Great One through direct contact, though its interpretation of the Great One's will is ambiguous at best.

All three ride on hovering platforms and protect the Great One while it performs its task. After its destruction, they show their flimsy loyalty by worshiping Cannonbolt, who had destroyed the Great One not minutes before. They decide to depart when Cannonbolt reverts to Ben, considering a mere human unworthy of their devotion. They appear in the episode "The Big Tick".
