Four Arms

* OA
* OS

**Four arms** is the Omnitrix's DNA sample of a Tetramand from the planet Khoros. He is Ben's 6th alien transformation and is a part of the Classic Set.

## Appearance

In Ben 10 (OS), Four Arms resembled a red, bulky, four-armed humanoid with four yellow eyes. He was large in size and had a muscular body, with his second set of arms being connected to the sides of his abdomen, and both sets of arms had small red spikes. The upper half of Four Arms' uniform consisted of black stripes connecting the pants and the sleeves to the collar of the neck on top of a white shirt, and his lower half resembled pure black pants. He wore fingerless gloves on each of his four hands. The Omnitrix was located on his left shoulder, on top of one of the black stripes.

In Ben 10: Omnitrix Awakened (OA), once the Omnitrix is recalibrated, Four Arms' physiology is updated to better reflect Ben's age and he is accompanied by a new uniform. He has spikes on his face and shoulders, as well as black hair, which is fashioned into a ponytail. He now has two fangs that you can see even when his mouth is closed. His fingerless gloves now are longer, have a white stripe and have holes on the back of his hands. The lower half of his uniform presents two stripes on each side of his waist. The Omnitrix is located on his chest, surrounded by four black bands with a white stripe in the middle.

## Abilities

* **Immense Strength**: Four Arms' incredible strength is unparalleled by most. He can use his four arms to great effect when in combat and is able to lift several times his own weight. The only aliens physically stronger than him are Way Big and Humungousaur at his full height, mostly due to their large sizes.
* **Enhanced Durability**: Four Arms' tough skin allows him to remain in a fight for extended periods, or at least, however long the transformation lasts before being timed out and reverting Ben back to human form. If unhindered by the Omnitrix's limiter, he can fight for considerably lengthy amounts of time without becoming worn down.
* **Shock Wave Generation**: Four Arms is able to slam his hands together, creating a shock wave that can shatter through opponents and objects.

## Weaknesses

* **Slow**: Four Arms' size and weight can become a great liability when in combat against quick opponents. This issue is shown in full force whenever Ben fights against groups of smaller, faster enemies, as Four Arms can quickly become overwhelmed and unable to react appropriately.

## History

* **2005 (OS)**:Four Arms was unlocked in **And Then There Were 10**, after which he was used several times during Ben's Summer Vacation.
* **Before 2010 (OA)**: After 2005 and before 2010, Ben practiced with Four Arms for an unknown amount of time, learning more about his capabilities and becoming more skilled with the transformation in general.

## Trivia

* Four Arms is one of Ben's personal favorites.
* In Four Arms' original Omnitrix Awakened design, his face presented a lot more spikes and growths. AwesomeAlan1 explains this as being a result of early experimentation, before he switched to making his designs more consistent with the Original Series.
* If Omnitrix Awakened was an actual animated property, AwesomeAlan1 has said that he would want Four Arms to be voiced by his original voice actor, Richard McGonagle.
