5 Years later Wiki

Ultimate Four Arms is the non-canonical Ultimatrix's DNA sample of a hyper-evolved Tetramand from the planet Khoros in 5 Years Later.


Ultimate Four Arms is a gigantic, muscular blue humanoid with two arms by default. He has purple muscles exposed across his body that can over-stack on top of each other. His feet have an extra two toes on the backside. He wears black overalls with white stripes.

The Ultimatrix symbol is located on his left shoulder.


  • Enhanced Physiology- Ultimate Four Arms' body is incredibly strong, durable, and resistant to damage.
  • Super Regeneration- Ultimate Four Arms has an increased rate of regeneration and is able to grow multiple limbs at will from anywhere on his body.
  • Muscle Overstocking- As a byproduct of his regeneration, Ultimate Four Arms is able to stack extra muscular mass onto his preexisting structure.
  • Excellent Structural Integrity- Ultimate Four Arms has a body that is excellent at maintaining integrity when faced with surmounting opposing forces. For example, the extra set of toes on his back heel allow him to hold up his body even when lifting or holding something that is technically too heavy for him to hold on his own.


  • Limb Count- Ultimate Four Arms has only two arms by default, therefore he needs to sprout an extra set to achieve optimal limb count.








  • Ultimate Four Arms' blue coloration is a reference to extant examples of blue Tetramands such as Kolar.
  • Ultimate Four Arms' design and abilities are inspired by the villain, Muscular, from My Hero Academia.
