Prerequisites: Blue Beetle or Booster Gold. The Bug can use all powers and abilities indicated on the Hazardous Environment dial and the Beetle dial. When The Bug would take damage, you may click either the Hazardous Environment dial or The Beetle dial instead. The Bug is only wrecked when its Piloted dial is knocked out.

Unlike Mastermind, which activates when a character is dealt damage, this power activates when the Bug takes damage.

Can you roll for Impervious first, then transfer any damage afterwards?

Do you have to choose to transfer or roll for Impervious?

Yes you can. You don't take damage until you roll for Impervious first.

i've a similar question. when using support on the bug, can you heal the beetle/hazardous dials? (as long as they haven't been ko'd of course)

i don't see why you wouldn't be able to but just making sure

I don't think you can. Those dials are specifically controlled by the Bug's rules and nothing in his rules say that he can heal them when he is the target of Support.

Correct........
