Shellhead (Universe 3008)

## Shellhead

**Shellhead** is the Omnitrix's DNA sample of a Nacrean from the seashores of the planet Kiusana.

## Appearance

Shellhead is a white-grey six-limbed pill-bug-like alien standing at 9 feet tall. He has four legs, two arms, a tail, and a large mouth. His eyes are found on opposite ends of its head, giving him binocular vision. He is covered almost entirely by a hyper-durable exoskeleton.

## Transformation Sequence

The transformation sequence begins with Ben's hands twisting and turning grey as two white epaulettes start forming on each of his shoulder. Ben's eyes then start departing from one another as Ben grows a new set of teeth from his lower and upper jaw and his head enlarges. The camera shifts to Ben growing a wide and stubby armored tail as the camera pan's around further revealing Shellhead's massive builds as he confidently posses with his mouth wide open ready to attack.

## Powers and Abilities

* Nigh-Invulnerable Exoskeleton - Shellhead's exoskeleton is invulnerable to almost all kinds of attacks. The greatest feat to date in regards to this power is when captain Hetun spit his Scalapascan acid at him and did virtually no damage to him despite Scalapascan acid being one of the most highly corrosive substances in the galaxy.
* Echolocation - While in sphere form he can sense vibrations through the ground around him.
* Spheroid Curling - Similarly to Cannonbolt, Shellhead can curl himself into a ball-like form that can also house other individuals within.
* Enhanced Digging - Since he is a Nacrean, he can dig at high speeds thru most terrain be it in his normal or spheroid form.
* Strong Tail - He can use his wide tail to knock off his enemies of their feet.
* Heat Resistance - Shellhead can endure high amounts of torrid heat with no problem due to his natural cooling mechanism.
* Hyper-Resistance - Shellhead is not that unprotected in areas without armor such as several limb-joints or even when he is not curled, as hes shown to be able to be hard pounded and fall from rather high distances without much of a hassle.
* Vertical Surface Scaling - He can scale the most steep of terrain with no problem and even scale completely vertical terrain in his uncurled form.
* Surface Attachment - He can fix himself in his curled form on any kind of terrain making himself particularly useful in situations such as avalanches and mudslides.
* Enhanced Bite - Although not as powerful as that of other aliens such as Ripjaws, Shellhead's powerful jaw made of bone aligned with parts of his exoskeleton overlaping his mouth can do severe damage to those unlucky to find their hands (or themselves) in his jaw. He can also rip thru various materials and bust doors and locks.
* Poisonous Gas Resistance - He can put up to various gases that would otherwise be lethal to other life forms due to his complex respiratory system filtering any potentially dangerous airborne compound.
* Limited Electrical Resistance - Shellhead can resist electrical attacks although not with ease as they may still harm him if the current is persistent or his a high enough voltage.

## Weaknesses

* Below-Average Speed - Shellhead is not a very fast alien as he can get quickly outrun.
* Ineffective Digging - Despite being a proficient digger he cannot dig thru very hard materials such various metals.
* Uncurling Restrain - While in spheroid form he can be restrained from turning back to his base form.
* Mobility Disadvantage - While in spheroid form his movement is restricted to digging downwards and can also ever so slightly from side to side. Neither does his hyper-resistance prevent him from just being lifted up and tossed away if he terrain or material on which he fixed himself onto is also lifted up, tho this rarely happens and requires a special kind of strength to do it.
* Vulnerable Eyes - His angle of vision is rather limited and his eyes are not covered with the same kind of hyper-resistant natural armor making his eyes his primary weak hotspot.
* Vulnerable Joints - As his joints lack any kind of protective armor they pose a drawback for Ben during situations of combat where an opponent might aim for them.
* Anosmia - Beinga a Nacrean and lacking anything functioning as a nose in the conventional way Shellhead is unable to detect smells such as those of smoke from a fire.
* High-Voltage Electricity - Shellhead cannot resist persistent electric currents from high-voltage sources.

## History

### Ben 10

* Shellhead was accidentally unlocked by Myaxx in Sailing The Stars when trying to unlock Spitter's pod. Ben entreated Myaxx to not lock-up the form because "he's cool". After Myaxx agreed to let him keep the form Shellhead was subsequently used again by Ben the next day to defend himself after the Pregnant Megalodoom's crew found him out.

### Ben 10 (Original Future Timeline)

* In Ken 10, Ben 10,000 added Shellhead's DNA to Ken's Omnitrix which he had made for his son's tenth birthday.
