Intelligente was a teacher robot who was incredibly smart and could teach a wide variety of subjects. He was also equipped with a 'homework attack', which just consisted of him launching missiles from his cap.

Intelligente appeared in episode 6 "Techno Teacher", where Eggman tries to use him to brainwash Chris's class. However, after throwing Mr. Stewart out, he takes a liking to the kids and ignores his orders from Eggman to brainwash them and actually teaches them and plays baseball with them. Eggman is not pleased and keeps everyone in detention, and it's only when Sonic arrives when Chris and his friends get to go home.
