The Great One (also known as The Tick)[merch 1] was a giant, tick-like parasitic alien that travelled from world to world, sucking the energy from the planets it landed on to feed itself.


It resembles a purple tick with four blue sack-like eyes, four purple insectoid legs, and an abdomen bigger than its own head. When it molts its shell, it exposes a pale whitish brown on the abdomen.


Not much is known about the Great One prior to its arrival on Earth, other than it was responsible for the destruction of Arburia, approximately one week beforehand. It is also worshipped by at least three alien individuals.

The Great One came to Earth with its worshippers in The Big Tick, intent on devouring the planet. During this process, it began to shed its outer layer and secrete fluid, to which the Great One’s worshippers gave Ben, Gwen, and Max Tennyson bricks to “cleanse” the Great One.

After its intent to consume Earth was revealed, Ben transformed into several aliens in an attempt to destroy the Great One, but it appeared to be invulnerable to their abilities.

Some time later, Ben reluctantly transformed into Cannonbolt. He soon learned that Cannonbolt’s species (Arburian Pelarota) was able to penetrate the Great One’s shell during its shedding process, and used this opportunity to destroy the creature from within.

Powers and Abilities

The Great One's absorption process poisoned and eventually made the planet it fed on implode. It also caused the landscape to mutate as an extra defense, making it very difficult to attack once the process had begun.

The Great One's shell appeared impenetrable to most forms of power and weaponry, as evidenced by when Grandpa Max and Gwen used fallen pieces of its shell to fend off the Great One's followers' attacks (which didn't even scratch them). None of Ben's aliens were able to break the shell until he finally used Cannonbolt to destroy it from the inside after it shed some of his shell.

The Great One secreted slime while shedding, which was sometimes acidic in nature.

On top of that, the Great One was followed by a group of aliens that worshipped the creature, following it "from planet to planet, galaxy to galaxy". They aided the Great One in its task, defending it from attackers.


The Great One was destroyed when Cannonbolt attacked it from the inside while it was shedding, as the newer shell was softer.

  • The Great One is like Galactus from the Marvel Universe, also well known for destroying entire planets in order to absorb their vast energy resources.
    • It seems to be a lot closer to Lavos from Chrono Trigger as he is similar in structure and has a similar technique in feeding off the planet.
  • The Great One was one of the toughest foes Ben has faced, with none of the aliens he had access to at the time (except Cannonbolt) being able to harm it.
