On the character's comment thread, there seems to be a second interpretation of this power that's cropped up.

My understanding is that any characters benefitting from this power would get a defense bonus based on the number of action tokens on that character.

The other interpretation that's come up is that collectively all characters get a bonus based on the number of action tokens on all the characters it would apply to.

So, let's assume Joker's Henchman #3 and two friends are all adjacent and each have an action token.

Does each character get +1 to defense, because of the action token they have on them?

Or does each character get +3 to defense, because between the three of them, there are 3 action tokens?

I'd go with the individual tokens, not collective.

Nothing says to add the tokens or otherwise use a total or sum.

Each bonus is determined individually for each character based on the number of action token they may (or may not) have.
