The Sans Helpers list

The Sans helpers list determines which characters will get in or not.
Remember. I can only have 2 more helpers left. So 

Added in = already added in as a helper.
Yes = will be a helper.
Maybe = might have a 50-50 chance of being a helper.
not sure yet = might need to see what the helper will do to attack.
Not getting in = will not be a helper because I either cannot think of any attacks, does not fit with Sans or I already have a intro against the character for Sans.
