Sheldon Oswald Lee is Jenny's geeky friend and admirer and supporting character in the Nickelodeon TV series My Life as a Teenage Robot.
He is voiced by Quinton Flynn.
Sheldon is Jenny's self-proclaimed romantic admirer. However, no matter what he tries, Jenny still refuses his romantic advances, though she does care for him as a friend. His Parents are never seen or mentioned.
Being skilled in robotics, Sheldon has created gadgets and modifications for Jenny, usually very unnecessarily bulky and extravagant, as well as doing minor repair work. He has even done more extreme modifications when requested by XJ-9, usually when Dr. Wakeman refuses to do them herself.
His skill has led to his creating a robotic alter-ego, The Silver Shell. Sheldon originally created the identity in an attempt to convince Jenny that robot boys were jerks, though this backfired when Jenny's affection for the robot grew even greater. As a hero, the Silver Shell has an imposing appearance, and a 'smooth' demeanor, and an excess of confidence, all qualities the human Sheldon lacks in his normal guise.
- In an interview, creator Rob Renzetti revealed he and his team would have loved to have seen Jenny and Sheldon as a couple before the series premature cancellation.
