You can't use the same free action twice in a turn, but I'm in doubt about the Shifting Focus trait: Could the same Batman shift focus more than once during a turn? Jump 6 squares, shift to sidestep 2 squares and outwit something, shift to charge 4 squares, then shift back to Batman #003.

I would think not - you are using a free action to activate the same game effect (Shifting Focus - Batman) more than once in a turn.

Once you have Shifted Focus, the new Batman has not begun your turn on the map, so I don't Think it is allowed to Shift multiple times.

Exactly. Even if the free action rule was null and void, the power itself stops you.

Yep - doesn't work for the underlined reason:

Okay, that makes sense. Thanks!
