How bout some Quad Smack baby!

– Quad Smack.

Quad Smack is the Antitrix's DNA sample of a mutant Tetramand/unknown hybrid and Kevin's equivalent to Four Arms.


Quad Smack is a humanoid alien that is approximately twelve feet tall, has well developed muscles, two pairs of arms with four-fingered hands, and light purple skin with black markings on the arms. A black goatee can be seen on his chin, and he has four red eyes: a main pair, and a smaller pair below them. His fingertips are also red. Quad Smack wears a sleeveless black bodysuit with red stripes and black boots, red spiked knuckles, and iron shoulder pads.

Quad Smack wears the Antitrix symbol on his chest.

In De-Fanged, Quad Smack had a long blonde wig, a few red parts of his clothes were light green, and his shoulder pads were painted with light green lightning bolts and small purple stars.

Powers and Abilities

Being part-Tetramand, Quad Smack shares many of the same abilities as Four Arms. Quad Smack's most prominent ability is his enhanced strength, being able to lift several times his own weight and punch through various resilient materials with ease. As such, Quad Smack's strength allows him to pick up and use anything heavy as a weapon, when needed.

By clapping all four of his hands together, or by slamming his fists onto the ground, Quad Smack can create strong shock waves powerful enough to destroy the surrounding area.

Quad Smack can jump several times his own height, at least seven stories up, in a single bound. He is also highly durable as he was able withstand Shock Rock's electric blasts with no damage.[1]

Based on Kevin's alterations to the Antitrix, Quad Smack is significantly stronger, and much more powerful, than Four Arms, having bested him in combat before.[2]


Being part-Tetramand, Quad Smack shares many of the same weakness as Four Arms.

Quad Smack's bulk sometimes is a disadvantage; all the extra muscle mass makes him relatively slower than other opponents, and his size, likewise, makes using things, or moving through areas designed for smaller species difficult. His immense size also makes him an easy target for enemy attacks.

Despite all his strength, Quad Smack can still be held down and defeated, his durability only lasting to some extent before growing tired or weary.

Due to Kevin's alterations to the Antitrix, Quad Smack is too powerful for the inexperienced Kevin to currently utilize to the fullest.
