Let's say I wanted to use Mario in a Rumble here, and possibly give him Cappy (Super Mario Odyssey).
Does Cappy count as a powerup, or a sidekick/outside help according to the rules of Khazan?
I ask because while he has powers that Mario can and does use in battle/in the field, Cappy IS in fact a sentient, living being (hell, he even has a sister).
EDIT: After looking it up, I have found that Cappy would DEFINITELY count as a sidekick/outside help, since his normal form DOES have a "body" under the hat.
