1. As for Swampfire, he evovles or Ultimates into a stronger body: a tree. Which cuts off his ability of regenerating because it just doesn't make any sense.

2. Echo Echo is living sound, he needs to be contained in a special suit. When he goes Ultimate, he becomes more robotic, which cuts off his ability of duplicating simply because a robot cannot.

Do you see how this occurs because of their physics and stuff?
