Who would win in a fight? A monkey with a sword? Or seven guards (who also have swords)?

Monkey all the way

Well the monkey seems to be smarter than all of them, so he would have better tactics. Also, monkeys can leap around much faster and easier, are smaller targets, have sharp claws, will not hesitate to bite and he may be able to use his tail to assist him. As Loki said, monkey all the way!

Abu!

everyone wnows that when a group of henchmen go up against a single, weaker foe, the individual wins.
Narative causality, duh.
