Kratos would just have sex with all the female smash character. They have kids and take him for child support making him work several jobs to support them and is unable to fight.
This leaves more of a level playing field but in the end Smash would win with no Kratos. Snake would be stealthy and take the unsuspecting out quick. Mario would crap fire balls and set the battlefield ablaze, and Captain Falcon would just "wreck" everyone else.
How has this truth not been brought up yet?
