Grey Matter

Grey Matter is a Galvan from the planet Galvan Prime.

Appearance
Grey Matter is a gray-skinned, frog-like, bipedal alien only five inches tall with large green eyes. The Omnitrix symbol is located on his back. He is Ben's second alien that has green eyes and has little minus signs in them.

Powers and Abilities
Grey Matter's size belies his great calculative and technical intellect, and when it comes to intellect he's second to none of Ben's other aliens however its unknown if Brainstorm can match him. He can create almost anything from spare parts and deduce the function of any device at a glance. Also, Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. Grey Matter's diminutive size allows him to squeeze into small spaces, and he can climb walls thanks to tiny suction cups on his skin. He also has sharp teeth, and his slimy skin makes him difficult to grab. Every time Ben chooses one alien when the Omnitrix chooses another, it's usually Grey Matter.

Advantages & Abilities
 * Has enhanced intelligence, which allows him to quickly understand and operate any form of technology, as well as determine an opponent's weak point. Additionally, he can sometimes control living things by stimulating certain parts of their anatomy, apparently applying the same basic principal as a horse and its reins.


 * Greymatter responds quickly to his surroundings.


 * His small size enables him to enter incredibly small spaces.


 * His intelligence is enhanced, which not only enables him to understand complex machinery, but also let him be more specific on his observations.


 * Microscopic pads on his fingers enable him to stick to any surface.


 * His teeth are sharp and can deliver a painful bite.


 * Has the advantages of a small animal, for example, he is strong in proportion to his size, able to survive falls from a great height due to his low body weight, and remain active in low oxygen environments since his body requires little air.

Weaknesses
Unfortunately, Grey Matter's size makes him unsuitable for battle, and hence Ben must outsmart his enemies while using the form. Grey Matter has, however, proved very valuable when used, as he is capable of hiding in very tightly compacted areas, and the form's supreme intellect has helped in many situations.

Disadvantages & Weaknesses
 * Unlike the other forms, Grey Matter is unable to participate in direct combat.


 * His size makes him incredibly weak and easily trampled on.


 * Not quick enough to escape from animals that see him, such as dogs.

Ben 10
Ben first transformed into Grey Matter in Washington B.C. when he saw that a gold Sumo Slammer card could be found in a box of cereal. Gwen found him looking for the card in the cereal boxes at the supermarket. Ben also transformed to Grey Matter to mathematically calculate the number of jelly beans in a large barrel, doing it in his head(it only took him about 4 seconds) to win a MP3 player. Although Ben rarely intentionally selects Grey Matter, he often finds himself in that form as a result of accidental transformations, such as in A Small Problem. In the episode Ken 10, Ken, the 40 year old Ben's son, turns into Grey Matter and hacks into the Omnitrix to access the Master Control. Most of these situations occur when Ben intends on transforming into a large, powerful alien, making his change into Grey Matter all the more ironic. It seems that Grey Matter is the one with the most accidental transformations.

Gwen 10
As a female version of Grey Matter, Gwen was tricked into it by Ben, something that annoyed Gwen, as Gwen was also being chased by a raccoon while in this form. Gwen as Grey Matter has Gwen's hair and has more oval shaped eyes.

Ben 10: Alien Force
Two-part series finale, after completing the Ultimatrix, to his disappointment Albedo discovers that Grey Matter isn't among his available list of alien forms and realizes the Ultimatrix is still synced with Ben's Omnitrix, forcing him to work with Vilgax in order to obtain the Omnitrix from Ben, only to have Vilgax double-cross him and take the Omnitrix for himself, ultimately leading to the destruction of Ben's Omnitrix forcing Ben to forcing Albedo to handover the Ultimatrix, thus leaving Albedo stuck in his Negative Ben form(on a side note it is somewhat ironic that Albedo actually wants to transform into Grey Matter but couldn't, which is ironic given that in the original series, Ben would often transform into Grey Matter unintentionally or completely by accident).

Ben 10: Race Against Time
Grey Matter appeared briefly in Ben 10: Race Against Time, where, after getting mocked by his peers in a popular hangout, Ben transformed into Grey Matter, and rearranged the circuits of the machines in the diner to create havoc.

Ben 10: Ultimate Alien
His Ultimatrix symbol is smaller and has been moved to his chest.

Trivia

 * In Ken 10, Ben 10,000's son, Kenny Tennyson uses Grey Matter's form to access his Omnitrix's master control by using Grey Matter's intelligence to figure out the correct combination. Neither Ben 10,000 or 10 year old Ben thought of doing this.
 * Grey Matter is the same species as the Omnitrix's creator, Azmuth. Azmuth's former assistant Albedo was also a Galvan before he created his own Omnitrix resulting in becoming trapped in the human form of Ben Tennyson(the Omnitrix's default form) and is unable to use Grey Matter's form because both his and Ben's Omnitrix are synced together(Ben didn't have access to Grey Matter's form at the time).
 * Before Ben obtained Nanomech, he was Ben's smallest form.
 * In the episode A Small Problem, an alien hunter captures Ben stuck in Grey Matter's form, ironic given that Albedo is a Galvan stuck in Ben's form.
 * Grey Matter appears to be based off of a gremlin given his powers, except enhanced intelligence.
 * In A Small Problem Howell states he is six inches tall.
 * In Secret of the Omnitrix Ben says he thinks the watch hates him. This happens when he turned into Grey Matter.
