What do you think is the best type of last boss storyline wise? Note: some of these can overlap
God/Creator/Super-being - An all powerful entity (the entity was either originally all powerful or has become all powerful before the chronological storyline/start of the game)
An Ascended Character - A character who has become all powerful or significantly more powerful during the chronological storyline of the game, meaning that at the start of the story the character was not all-powerful or as powerful as he is when you fight him as the last boss
A Rival - The main character's rival throughout the story
Just Another Foe - Essentially just another enemy, not all powerful or significantly more powerful than all the other enemies the main character has faced in the game
Creation - An entity which was created by someone and is either 1) fulfilling its purpose or 2) gone out of control
Summoned Being - A being that was summoned into the character's world
