Four Arms has a large muscular body with extra arms and red skin. He has four green eyes, a black beard and his hair is in a ponytail. Four Arms wears gold, silver and green gladiator-like armor, much like other Tetramands.

The Omnitrix symbol is located on his sash below the stomach.

  • Enhanced Jumping - Four Arms can jump several times his own height in a single bound.
  • Enhanced Durability - Four Arms has high durability due to his tough and thorny skin.
  • Heat Resistance - Due to his tough and thorny skin, Four Arms is almost fire-proof and laser-proof.
  • Slime Spit- If under the effects of a cold, Four Arms can sneeze out a spray of slimy snot from his mouth.


  • Lack of Speed - Due to Four Arms' massive size, he can't run as fast as most of Ben's other transformations.
  • Cold Virus- If under the effects of a cold, Four Arms' strength and stamina can be severely reduced.
  • Tight Spaces- Because of his large size, Four Arms is not effective in small spaces.
