It is a coin flip between my two favourite characters in my gaming library
My Dragonborn in Skyrim, because a)I would be able to fuck so much shit up, b) I have access to spells,SPELLS, I could turn fucking invisible if I wanted 2 and c) I am immortal with the soul of a mother fucking DRAGON, who is running for president next time, the immortal who can kill you all with his voice that is who.
Master Chief because a)Get some pretty bad-ass armour that can kill anyone it wants and is impervious to all modern weapons except a nuclear bomb, b) I am a beast even without the armour, I can run at 23km an hour, I am a master of all forms of martial arts, I have unbreakable bones and I have a pretty sexy voice, and finally c) I am the last of the Spartan II's, and thus I am the best and anyone who thinks differently can be kicked straight to the moon like a ***** who doesn't like bananas.
