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 like Timmy Turner's, except now that he's popular, he's considered not as miserable.
