Colossal Fin

**Colossal Fin**  is the Omnitrix's DNA sample of a To'kustar, a race of ultra-rare, gigantic aliens that are created in Cosmic Storms.

## Appearance

### Ben as Colossal Fin

Colossal Fin is a white colossal humanoid creature with a large fin on his head, which is black at the front and red at the bottom. He has blade-like growths on his shoulders and spikes on his waist. He also has red arms with two black lines and white fins on the elbows, wristband-like outgrowths on his wrists and yellow eyes on his head with two extra eyes protruding on his cheeks, one on each. He has red feet with two toes, a black sandal-like covering on the middle of his feet and three black lines on the side of his neck. The red parts of Colossal Fin's body are made of an unknown cosmic material with metallic properties. Ben 10,000's Colossal Fin is identical to this design.

In **Alien Force** and **Ultimate Alien**, Colossal Fin's head fin was red on the front and black on the bottom, his arms were white with red fins coming out of them and his neck and wrists were black. Colossal Fin's eyes are green and he did not bear the extra ones on his cheeks. He lacked the stripes on his arms as well as the blades on his shoulders and waist. He also had red boot-like feet and did not have the sandal-like coverings.

In ***Destroy All Aliens***, Colossal Fin looked mostly the same as in **Alien Force** and **Ultimate Alien**, except the red parts were colored to match his portrayal in the original series.

In **Omniverse**, Colossal Fin has two red lines on his neck, the blades on his shoulders and waist have returned and are red and he also has black fingerless gloves, similar to the ones Four Arms wears in the same series. He is now more muscular, his head is less skull-shaped and has eyes on his cheeks again, which are more metallic. The fins on his arms are longer and he has regained the stripes on his arms and legs, and the wristband-like outgrowths on his wrists. Uniquely, both 16 and 11-year-old Colossal Fin share the exact same design.

Colossal Fin wears the original Omnitrix/Ultimatrix/Omnitrix symbol on his chest.

### Mad Ben as Mad Colossal Fin

Mad Ben's Colossal Fin is near identical to Ben Prime's Colossal Fin in **Omniverse**, except for orange replacing the eyes and the red parts. He also wears gray shoulder pads with orange spikes, spiked shoes, and orange wraps around his forearms and calves. His arm and head blades are also serrated.

## Powers and Abilities

Colossal Fin is very strong (even for his size), being able to hurl targets into orbits from planets with an atmosphere as thick as Earth's, as shown when he threw Vilgax (who was Colossal Fin's size at the time) into orbit from Primus. He can even lift objects larger and heavier than him, as he managed to lift the Hyperspace Jump Gate. Technically speaking, he is powerful enough to destroy a small planet.
Colossal Fin has great durability, being able to withstand attacks from enemies while barely even feeling them. He is also resistant to extreme temperatures.

Colossal Fin can jump very high. He also has extremely quick reflexes, being able to react to Milleous's Incursean Conquest Ray.

Colossal Fin is very skilled in hand-to-hand combat, as seen when he fought giant versions of Vilgax, the Garbage Monster, Trombipulor, and Malware.

Colossal Fin can shoot a powerful cosmic ray from the outer edge of his right hand by crossing his arms together. His cosmic rays are powerful enough to overpower the Incursean Conquest Ray.

Due to the nature of his species' creation, Colossal Fin can survive in the vacuum of space.

Colossal Fin has enhanced speed, similar to XLR8 and Fasttrack albeit with him leaving a red and white trail behind. Colossal Fin also has a massive stride, so he can get to his destination quicker than other aliens.

Colossal Fin is extremely strong, being able casually thrash around an Arburian Pelarota and break free of ice generated by a Necrofriggian. His pure To'kustar DNA makes him more powerful than mutated Way Bads, whose DNA is diluted due to being a mutation.

Colossal Fin is nigh invulnerable, being able to easily withstanding anything from a multitude of alien attacks.

Colossal Fin has superhuman reflexes and agility, as he can fight on-par and dodge an Appoplexian's attacks.

Colossal Fin can shapeshift, allowing him to form weapons from his limbs.

Colossal Fin can project powerful laser beams from his eyes and hands. These lasers are also capable of incapacitating other species and leaving humans in an immobilized yet disassembled state.

Colossal Fin possesses telekinesis and can teleport.

Colossal Fin has terrakinetic abilities that can be used in unison with his telekinesis, as he can make large pieces of rocks emerge from the ground by raising his hand upward and lift boulders into the air.

Colossal Fin can open dimensional portals to help him travel through the Omniverse.

Colossal Fin is able to disintegrate objects that get close to him.

Colossal Fin is able to easily remove Omnitrixes from the users' arm. He is then able to store the Omnitrixes in his body.

Colossal Fin has the ability to grow to a gigantic size, as demonstrated by Colossal Fin.

Colossal Fin can cause massive storms to appear and terraform a planet with his presence, as demonstrated by Colossal Fin.

Colossal Fin can survive and cause timeline destruction.

Being a To'kustar, Colossal Fin can increase his size, cause massive storms to appear, and terraform a planet with his presence. He potentially has the power to take over the universe

## Weaknesses

Colossal Fin sometimes forgets how strong he is, as shown when he accidentally destroyed the statue of Zavin by leaning on it. His size also gives him a slight mobility issue, since he has to be careful where he steps to avoid crushing objects and people around him, and easily gives his location away.

Because of his size, Colossal Fin cannot be used inside buildings or confined spaces.

Since Colossal Fin's fin is a weak spot, a hit to that area can paralyze him.

Despite his immense durability, Colossal Fin can still feel pain, as Vilgax clawing his hand felt like a small but painful bee sting.

Despite his immense strength, Colossal Fin is physically weaker than opponents with sufficient strength, such as a giant Trombipulor.

Colossal Fin is vulnerable to electricity, which can incapacitate him.

Like other organic beings, Colossal Fin is vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.

Certain beings that are about as small as Nanomech can go inside Colossal Fin's head and attack him.

A Kineceleran can generate a tornado strong enough to lift Colossal Fin off of his feet, as demonstrated with the Way Bads.

Colossal Fin can be harmed by Argit's quills, as also demonstrated with the Way Bads.

Colossal Fin can be controlled by Vladats via their Corrupturas.
Colossal Fin can be harmed by high-pitched noises, such as a Sonorosian's sonic screams, if they were to get close enough to his ears.

This weakness was first referenced when Shocksquatch made an unsuccessful attempt at attacking a Way Bad using a megaphone made from Echo Echo's DNA.

Colossal Fin can be eaten by a Gourmand, though he would first have to be chopped up into bite-sized chunks.

Colossal Fin can be subdued by the Hephestan Neuro Grip, but only if this move were to be performed by beings with hands much bigger than Slapstrike's.
