Timmy Tinkle was like Red Tornado and Stel a robotic creation. While it seemed his origin was benevolent, in actuality his creator had like Tornado's architect T.O. Morrow attempted to trick his unwitting victims into trusting the automaton for his own greedy gains. Inserting Timmy into television station WHIZ, the station owner Morris wholeheartedly accepted the newly "freed" robot to apply for a job there.
And in fact Tinkle performed some heroic deeds causing first news anchor Billy Batson and, soon thereafter, his superhero alter ego Captain Marvel into befriending the bot. When it was discover that Timmy has stolen items from the station, Cap was determined to disassemble the droid until he saw a radio transmitter implanted in the erratic electronic.
While not having massive power like Red Tornado of Earth-Two (later of Earth-One) and Stel the Green Lamtern of Earth-One's universe (later deceased), as that level of energy emissions was exhibited in another robot of Earth-S named Mister Atom who fought Captain Marvel repeatedly, Timmy Tinkle was still every bit as dynamic.
