Yes, Ms. Lion is a he. I don't want him to save the day, just help. Maybe have some power that allows him to point out just the right place to hit or something. Useless in everyday life, but still a power.
You can't have him along and not have him do something important, even if he doesn't end up with powers. He needs to do something that makes it a good idea he was on the team.
If he doesn't do anything important, then hopeful this is a test series that works and we get more where we can see Ms. Lion do something important.
