does it have to be video game characters, because if not, then i would bring some awsome anime charachters
Silphil from slayers (she can heal any wound, purify any injury, and is at least somewhat smart) meaning i wouldn't have to worry even if i lost an arm
Amilia from slayers (she can use her powers to purify, meaning mass zombies becoming normal again)
and then of course Lina from slayers (mass distruction doesn't even come close to describing what she can do, more like she is death incarnent)
with those people i wouldn't have to worry unless we ran out of food, then Lina would turn on us, not a pleasent thought, but on the bright side, it would be the end of a ZOMBIE apcolypse, but it would create another kind of apcolypse (the kind where the world goes boom for you slow people)
