The Mutants who were used by Project Purgatory to open a dimensional portal to Limbo. They were handed over to the government in good faith but Project Purgatory's true plans were to secretly weaponize them as a contingency against mutants. However, their base was attacked and General Combest sealed off a dimensional portal that stranded Project Purgatory in the hellish Limbo dimension for a total of 26 years. In order to protect himself and his soldiers in the hellish dimension, General Ulysses conditioned the Inferno Babies to become merciless super-soldiers who are loyal to him. When they first confront the New Mutants they are 11 in total.
The Inferno Babies where created by Louise Jones Simonson and Jon Bogdanove and first appeared in X-Terminators Issue #2 (1988). Years later, they made their first appearances as adults in New Mutants Issue #16 (2010). These versions where created by Zeb Wells and Leonard Kirk.
