Looking at this again, I see that Bender is more vertically challenged while Jenny is more horizontally challenged. This is good because, unlike Mega Man and Bass (In which Bass was so much better than Mega Man it wasn't even funny) they are evenly matched.
In that case, I think ** and * will work. You won't need more because you don't have values like "NORMAL" or "BAD". Why do I suggest stars? Actually, some people won't understand what's better: "GOOD" or "OK".
I know, but if I made Jenny both fast and strong, it could make her cheap, and it could make Bender useless, I just had to make it this way so the usefulness of each character stays intact, I know its hard to, but still, Jenny is a better character to use in my opinion, just because of the laser
