Atomblast was a former soldier for The Battle Of Hybrids, being on the red team. He turned against Hybrido in the Frostec movie, motivated to join Frostec and Harmheat against the threat Hybrido was exposing to humanity.

Atomblast's Death
He died while saving Jono Marwe from Ethan Strange, tied between the two universal diamonds when Ethan created the time portal, instead accidently causing Atomblast to fall in while pushing Jono out of the way. Jono was horribly abusive and mean to Atomblast, but deep inside her, she loved him and didn't want to hurt him, but was forced due to her dark past. Atomblast saved her even though she was hateful to him. That teaches a lesson. Now, Jono was actually hateful to him for a reason. It helped him live longer. Without knowing she really loved him, he would have shot himself, thinking nobody cared about him. Jono, was worth saving. So he did it.
