So. You want to know about Pyromaniac Isaac, hmm?

Well, then. Let's begin at the beginning¹⁾²⁾.

Before he arrived on the Island, Pyromaniac Isaac was a stuntman. He did a great many stupid and completely ridiculous things^3)4)5)6)7).

Due to his numerous head injuries as a result of his actions, he doesn't remember very much else.

One day, after his girlfriend was raped and murdered, his house burned down, and he got fired, he was mugged in an alleyway as he took a shortcut to a hotel. These muggers were Network personnel. They knocked him out, dragged him to the Island by speedboat, and dumped him on the shore.

On the Island, Isaac first interacted with Ihpkmn, whom he thought was wearing a Cthulhu mask⁸⁾. After screaming his head off and knocking himself out⁹⁾, Isaac came to terms with the insanity of the Island.

Recently, however, he has noticed that he has become immune to being burned, and has tested his theory multiple times by setting his hands on fire deliberately. Having proven himself correct, he is determined to learn to become a pyromancer.

That was a long time ago. Since then, he's been infected¹⁰⁾, defected¹¹⁾, fell in love¹²⁾¹³⁾, founded the League of Unpopular Superheroes¹⁴⁾¹⁵⁾, got possessed by Lythar¹⁶⁾, unpossessed by Lythar, got the shit cut¹⁷⁾ out of him by Hank in a war of Gods¹⁸⁾, became a ghost after dying, unbecame a ghost¹⁹⁾²⁰⁾, and had some normal times with Heather for a while.

Then he proposed²¹⁾, they had a wedding²²⁾, became a woman²³⁾²⁴⁾, unbecame a woman…and is having good times with his 'froker²⁵⁾ wife.
