Initially, Baby is single-minded in reviving the Tuffle race and exterminating the Saiyans. Over time, it is shown that he is cunning enough to dominate the Z Fighters, possessing Vegeta
and successfully restoring the Tuffles' home planet. However, befitting
his name, Baby is also incredibly childish and immature; he is very
prone to taunting, and flies into a rage if he is teased enough.
Ironically, despite seeing the Saiyans as a barbaric race, he displays
enjoyment in battle as well; upon becoming a Golden Great Ape, Baby
pretends that he is on a mindless rampage (which is a common occurrence
among the Great Apes and Golden Great Apes), and massacres countless
followers as a means of testing out his abilities. He is very
intelligent, and has an extremely egotistical and selfish personality.
Baby cares very little if not at all about the lives of others, as he is
seen killing his own followers who worshipped him like a king. But he
still is shown to care about other things, as he gives credit to Bulma,
who was probably made his queen, most likely due to Vegeta's affection
for her, for giving him energy with the Blutz Wave Generator, and he
does not want the battle to destroy his own planet.

After he receives energy from his followers, becoming Super Baby
Vegeta, his cruelty becomes more pronounced, and he states that each and
every living being should be considered his slave. Due to the Tuffle King's
DNA within Baby, he is also tremendously proud, and he prefers to fight
one-on-one. Being one of the two survivors of the Tuffle race (the
other being Dr. Raichi),
who were all but exterminated by the Saiyans, he bears a deep hatred of
the Saiyans. Unlike other villains of the series in its entirety, Baby
is not instinctively acting on evil intentions alone. He is an
antagonist to the protagonists of the storyline, but he is seeking
vengeance for all the misery that was brought unto him and his own race
by the Saiyans. He does want to pay back his pain and suffering, but the
desire to do so is a direct cause of what happened to his own race.
During the Saiyan-Tuffle war, the last of the Tuffles
created genetically superior life forms, parasite-like organisms, which
they infused with the DNA of the Tuffle King. These organisms were
spread throughout the universe around Age 730, with the overall goal to destroy the Saiyans in revenge for the destruction of the Tuffles by King Vegeta and his Saiyan forces. Baby was the first Tuffle parasite to return and try to obtain vengeance against the Saiyan race. While drifting through space, in Age 735,
Baby swears vengeance against the Saiyans for wiping out the Tuffles
and furthermore devises the "Universal Tsufruization Plan" in order to
revive the Tuffles. In Age 740, Baby manufactures Dr. Myuu
in order to gather the resurrection energy he needs to obtain a
powerful body. Baby programs Myuu with the method of developing Machine Mutants, and production begins on Luud, M-2, and the others.[3]
Seemingly created as a "last resort" by the demented Machine Mutant Dr.
Myuu, Baby is a parasite whose purpose for living is to see through the
annihilation of the Saiyan race and domination of the universe in the
name of the Tuffles. However, as his name implies, Baby is highly
immature and is prone to fits of rage and panic, as well as not taking
his battles seriously. It is also implied that "Baby" was not his
original name, or at least that this is not what he was intended to be
dubbed, as Baby does not initially recognize the title and before long
begins to dislike it. During the battle between the Baby-possessed Gohan and Goten against Vegeta, Baby reveals to Vegeta his true Tuffle background and how he was created.
