Blazestone

Blazestone is a character from The Incredibles. She is a super who was once arrested and jailed before being recruited by the National Supers Agency.

Powers
Pyrotechnic kinetic discharge

Heat control and resistance: Blazestone is able to control heat and, as such, is unaffected by intense heat. She can fly by riding upon heated air.

Interdimensional travel: Blazestone may also have some method of traveling interdimensionally, since she forgets which dimension she is in during her agency voice recording.

Weaknesses
Unpredictability: Blazestone was known for being unpredictable and highly temperamental. This led to the NSA keeping her under close supervision.
