The Overlord

The Overlord is a Legendary pet in Bubble Gum Simulator. It can be obtained by hatching a Nightmare Egg. The chances of hatching it are 1 in 4 million (0.000025%), or 1 in 2 million (0.00005%) with the Lucky Chances gamepass. It is a secret pet, only somehow not appearing in pet catalogs if obtained.

Trivia

 * It is the 4th rarest pet in the game (1 in 4 million chance). It was also the best pet as of Update 3 until Festivus came out in Update 4, Leviathan in Update 5, Dogcat and Gummy Winged Hydra in Update 9, and The OwOlord in Update 11.
 * The shiny version is approximately 1 in every 400 million eggs, making it almost impossible to get. However, it is easier to sacrifice 10 Overlords to make a shiny instead.
 * This pet was first hinted on Isaac’s tweet on Twitter saying “And you thought there were only 9 pets in this new egg...”
 * As of Update 13, this pet now has 4 reskins: the 2018 Overlord, the Jelly Overlord, The OwOlord and the Gummy Overlord. It is currently the 2nd best Overlord.
