I normally avoid these types of question, but in this case I'll oblige with the correct answer:
a) if its a Zelda game... Link - it's his game D'uh.
b) if its a God of War game... Kratos - it's his game D'uh
c) real life... they don't exist in real life, D'uh
Also I prefer Pluto to Goofy...
Try to be reasonable... its easier than you think...
