This is less of a versus thread and more of a "can he replicate those feats?" thread.

Because otherwise, it's pretty obvious Ken could roflstomp most Halo threats.

The challenges: Ken has to survive/perform every feat Master Chief has of orbital reentry or stuff of that nature. Chief has hit the ground covered in a fireball from orbit twice. Can Ken survive a similar experience? .

Also, can Ken do this? :P

Can Ken hit hard enough to destroy Guilty Spark?

Ken vs The Flood. I'm curious on 2 things. 1: Can they physically infect him if they latch on properly? Or will he push the infection out of his body?

2: Can he engage in dialogue with the Gravemind and resist the Logic Plague?
