Giant-Manster is the Omnitrix's DNA sample of a To'kustar, a race of ultra-rare,[pop-up 1][1] gigantic aliens that are created in Cosmic Storms.[MW 1]


Giant-Manster looks most the same as Way Big in Omniverse except his skin is greyish blue, the red parts on his body are blue, his primary eyes are light blue, and his secondary eyes are gold. The Omnitrix symbol on his chest is blue with a gold outer casing.

Powers and Abilities

Giant-Manster is very strong (even for his size), as shown when Way Big defeated Vilgax (who was his size at the time) and threw him into orbit.[2] Technically speaking, he is powerful enough to destroy a small planet.[JK 1]

Giant-Manster has great durability, being able to withstand attacks from enemies while barely even feeling them. He is also resistant to extreme temperatures.

Giant-Manster can jump very high. He also has extremely quick reflexes, being able to react to Milleous's Incursean Conquest Ray.[3]

Giant-Manster is very skilled in hand-to-hand combat, as seen when Way Big fought giant versions of Vilgax,[2] the Garbage Monster,[4] Trombipulor,[5] and Malware.[6]

Giant-Manster can shoot a powerful cosmic ray[DM 1] from the outer edge of his right hand by crossing his arms together.

Due to the nature of his species' creation, Giant-Manster can survive in the vacuum of space.

Giant-Manster has enhanced speed, similar to Speedyquick and Fastcat.[4] Giant-Manster also has a massive stride, so he can get to his destination quicker than other aliens.[DJW 1]


Giant-Manster sometimes forgets how strong he is, as shown when Way Big accidentally destroyed the statue of Zabin 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.[7]

Because of his size, Giant-Manster cannot be used inside buildings or confined spaces.

Since Giant-Manster's fin is a weak spot, a hit to that area can paralyze him.[8][9]

Despite his immense durability, Giant-Manster is weak against opponents with sufficient strength, such as a giant Trombipulor.[5] Similarly, Way Big felt pain when Vilgax clawed his hand while Way Big was holding him.[1]

Giant-Manster is vulnerable to electricity, which can incapacitate him.[9][10]

Like other organic beings, Giant-Manster is vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.[11]

Certain beings that are about as small as Teeny-Weeny can go inside Giant-Manster's head and attack him.[12]

A Kineceleran can generate a tornado strong enough to lift Giant-Manster off of his feet, as demonstrated with the Way Bads.[3]

Giant-Manster can be harmed by Argit's quills, as also demonstrated with the Way Bads.[3]

Giant-Manster can be controlled by Vladats via their Corrupturas.[DJW 2]

Giant-Manster can be harmed by high-pitched noises, such as a Sonorosian's sonic screams, if they were to get close enough to his ears.[DJW 3] 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.[13]

Giant-Manster can be eaten by a Gourmand, though he would first have to be chopped up into bite-sized chunks.[DJW 4]

Giant-Manster 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.[DJW 5][DJW 6]


In Store 23, Giant-Manster was mentioned when Ben 23 brought up a time he "accidentally" crushed a local smoothie store as him.
