Agent 47 will be out to kill you after 48 hours, and you can choose 1 character from any video game to protect you. Who do you choose, and what would you do?

From my experience agent 47 is a human , just stronger, kind of like a hardcore zombie, he still a human right? If i could choose from any videogame i would choose the doom slayer. Doom slayer fought against the whole hell and can beat demons, a genetically modified human couldn't do shit against him. He would shoot him 3/4 times before getting his ass beaten to death. The doom slayer has a lot of powerful guns compared to the ones agent 47 has. If agent 47 doesn't kill me in a way doom slayer can't protect me (like taking a shower or poisoning me somehow) doom slayer would surely be able to protect me and probably kill 47.
