Dr. Lychee

Yes. Dr. Lychee is a Tuffle scientist driven by an intense hatred of the Saiyan race. He was among the Tuffles who perished when the Saiyans conquered Planet Plant around Age 730.

Before his death, Lychee preserved his will and scientific knowledge within a device called Hatchiyack, a supercomputer designed to amplify and channel hatred into physical power. Hatchiyack later allows him to return as a Ghost Warrior and to summon other Ghost Warriors.

Lychee enacts his revenge by deploying Destron Gas generators across Earth, producing a toxin lethal to all living things. He also uses Hatchiyack to summon Ghost Warriors based on fallen villains like Frieza, Cooler, Turles, and Lord Slug, who regenerate endlessly as long as Hatchiyack continues to operate.

The Z Fighters track Lychee to the Dark Planet and confront him directly. He is difficult to destroy because he is already dead, reforming as a ghost through Hatchiyack's power, but the heroes finally push past him and Hatchiyack itself transforms into a massive warrior form for the final battle.

Lychee's character design and obsession with anti-Saiyan revenge later influenced the creation of Dr. Myuu in Dragon Ball GT. Both are Tuffle-aligned antagonists whose hatred of Saiyans drives their machinations.
