[2.2.10] You are immune to crushers while transforming into Super.

If anyone is in their Super Form Transformation animation while being crushed... they are able to dodge death. Requires a bit of timing but this can also happen with custom animations, such as Burning Forms via Sol Emeralds from RushChars which has a longer transformation animation so more likely to dodge death from crushers.

It doesn't seem you can dodge death with Death Pits or Instant-Kill sectors, however...

EDIT

You also can't dodge death from drowning in water or space during the transformation. Same with the Timer Over.
