Baby

ベビー

Baby is a fictional parasitic alien supervillain in Dragon Ball GT, which is based on the Dragon Ball manga by Akira Toriyama. He serves as the series' primary antagonist and is the longest-running villain throughout the show.
At first, Baby is solely focused on reviving the Tuffle race and wiping out the Saiyans. Later, it becomes clear that he is cunning enough to overpower the Z Fighters, possessing Vegeta and successfully reclaiming the Tuffles' home planet. Nevertheless, Baby is also remarkably childish and immature; he frequently taunts his opponents and flies into a rage if teased too much. Ironically, although he views the Saiyans as a barbaric race, he also takes pleasure in battle.
