Cooper Daniels is a 13-Year-Old inventor and hacker, widely believed to be the smartest kid on Earth. He possesses technopathic abilities that allow him to hack, build, and upgrade anything with a mere thought. His expertise caught the attention of Kevin Levin and the two frequently collaborated inventions and technical modifications, especially with alien technology. Eventually he joined Ben Tennyson’s team to defend the Earth from alien threats.

• Cooper is three years younger than Ben and Gwen.

• Kevin caught Cooper stealing some of his alien tech. But after seeing what Cooper can do, Kevin offered to aid him and even trade some tech for further upgrade. The two are best friends.

• Cooper has a huge crush on Gwen Tennyson, fawning over her every time they meet. Gwen thinks it's adorable but she sees him as a younger brother. Kevin thinks it’s hilarious, especially once he starts dating Gwen.

• Cooper is an avid gamer, regularly playing MMOs and fighting games with Ben and Julie.

• Cooper’s grandfather was a plumber just like Max. His powers are the result of his grandfather using an experimental techno-organic virus to save his life as a baby.

• Despite wanting to get in shape, Cooper is comfortable with his appearance and prefers to rely on his mind rather than muscle.

• Cooper’s mind and abilities impress Azmuth greatly. 

• Cooper is too scared to even touch the Omnitrix with his powers.

• Cooper will become a plumber once he is of age.

• In the future, Cooper will decide to live on Galvan B to both work with Azmuth on inventions, and to live amongst the Galvanic Mechamorphs.

Cooper is quite a well-meaning and friendly kid, although he can be quite naive as well. He can be a bit nervous but is still brave enough to fight or handle dangerous situations when the time calls for it.
