Hot Shot

Isaac is the purely comic relief character. He is not very intelligent and terrible at using his powers to the point he is a liability. His only saving grace is that he is not mean or anything.

He is the lone member of the Swimming Club.

Story
Isaac didn't play an important role in the story at all. In fact, he even quits being a hero near the end of Season 1 and goes to Law School instead.

Power
Isaac's power, called Firebolt is a normal pyrogenesis power, except for the fact that he cannot control its energy output. It can come out at full blast: a fiery inferno or a tiny spark, all seemingly at random.
