Think about it.
The secret invasion allows for any character to be returned whole (perhaps alive from presumed dead) and intact without any baggage from previous storylines. Hank Pym never created Ultron or hit Jan, Skrull Pym did that. The last thing Pietro remembers is being in the Savage Land- he never married Crystal, never went insane or evil about a half dozen times. Pym and Quicksilver could be returned to pristine quality. What an amazing tool to be able to utilize to restore characters to previously unrestorable and unforseeable greatness.
A list of characters who could use a recreation
the aforementioned Quicksilver and Yellowjacket
Scarlet Witch
Hawkeye
Wasp
Vision
Mockingbird
Goliath
Alpha Flight
Ant-Man
Swordsman
Mantis
Moondragon
Cap (of course)
If you were in the planning room at Marvel, what event or character development would you like to see erased.
As you could probably guess, I'd like to see Pym's and Pietro's history unwritten and rewritten.
