Does Nightcrawler's BAMF cost an action, and can he leave an enemy-occupied zone with it?

Question

Accepted Answer

No action is needed. BAMF is not an action even though its text says move, and it costs an increase in Hunger instead. Nightcrawler can teleport out of a zone occupied by enemies, and can use it while enemies share his zone.
