Timmy looks very similar to his alternate counterpart, still having spiky brown hair, blue eyes, and buck teeth. Though, unlike his alternate counterpart, Timmy Tang wears color-coded clothing to what Trixie usually wears, which is bright purple. He wears a purple hat, corresponding to Trixie's headband, a purple short sleeved turtleneck, corresponding to Trixie's turtleneck, and wears white pants and boots, corresponding to Trixie's white skirt and boots. At the school dance, he wears a green tuxedo and a green hat, similar to Trixie's costume in "Take and Fake".
Timmy Tang's personality is almost an exact copy of Timmy Turner's, except now that he's popular, he's considered not as miserable.
