He takes over the fifth alternate realm called The Forsaken Future. he controlled all the universes and altered them so that the player cannot obtain the eggs

After the player collects all the eggs, Rabid Rabbit appears as the final boss in the Forsaken Future. the player then uses a sword and weakens the Rabid Rabbit. but the Rabbit doesn't give up as it escapes but somehow leaves an egg of his behind.

afterwards, Lucky Lapin is freed and the Eggverse is back to normal. But Rabid Rabbit will return for revenge in a different universe.

Egg Hunt 2018: The Great Yolktales - Return of the Rabbit
after Rabid's defeat in the Forsaken Future, he travels to Robloxia and captures the Heroes of Robloxia, except for Amethysto, who is the only one who can save his teammates. Rabid summons Robot Rabbits to attack him but he uses his plasma beams and reroute the power to the Turrets. after he rerouted all the turrets, they zapped at him and presumably sent Rabid Rabbit back to his dimension. Amethysto earns a prize for his heroism afterwards.

It's possible that the Rabid Rabbit might return for a different event.
