Tini first appeared in The Galactic Enforcers. Tini developed a crush on Four Arms, but retained her feelings no matter what alien Ben was. Later on in the end of the episode, she started dating Synaptak after he saved her.
An alternate timeline Tini makes an appearance in the episode Ben 10,000.
Tini returns in Vengeance of Vilgax: Part 1, where she and Synaptak were defeated by Vilgax after they attempted to interfere with Vilgax and Ultimos' fight, with Tini being trapped in a hole in a wall, behind some rubble.
Powers and Abilities
Tini possesses the same super strength that most Tetramands have and also has the same lack of speed. Although it does tend to come in handy, using moves like the Sonic Clap.
As later revealed in the Omniverse series, since Tini is a female Tetramand, she is traditionally stronger than the males of her kind.
