Dave the Intern

Dave is a minor villain in Sonic Boom TV first appearing in episode 7 "Double Doomsday". He is a mechanical teenage genius who wants to become an evil genius equal to Dr. Eggman and presumably, take over the world.

Double Doomsday
When Dr. Eggman had visited the cafeteria where Dave worked, Dave put an expression on the doctor, who then stated him as a helper and led to his base. Dave wanted to become an evil genius, praising Dr. Eggman for his achivements and status, but the latest forced him to do such primitive things as cleaning the base. On his duty, he heard chat of envying Orbot and Cubot and then dissassembled Cubot, leading to Orbot to use help of Sonic the Hedgehog.

As Dave tired of his work and asked Dr. Eggman for higher job title, the latest asked him to wait several weeks for it. Dave became enfuriated by it and then locked himself up in the workshop to do a Doomsday Device equal to the one which was created by Eggman himself. As Sonic and Tails made both geniuses to overpower their machines, the energy from them created a black hole which was erased by Sonic.

As for Dave, due to his actions, Dr. Eggman fired him from the post of his helper, leading to Dave's returning to the cafeteria, swearing for revenge to both Eggman and Sonic.
