I'm The Ice King In Adventure Time?

A man dies and is reincarnated as Simon Petrikov AKA the Ice King in Adventure Time. Watch as he tries to master magic and stay sane as the crown is slowly breaking his mind apart. This will be sorta slow plot as you know... Simon is 1000+ years behind the start of the plot of the show. Also, this is my first try writing a character like this for this series. Mc will behave similarly to the original Simon Petrikov but instead he will be more invested in magic and generally just smarter/less cartoonish. I'm trying to have him be a really smart ancient guy by the time the plot starts.
