[Marvel] and [DC] What fears and or hexes would Scarlet Witch use to take down the Justice League? What do each of them fear?

Let's say the members are:
Batman
Superman
Wonder Woman
Green Lantern (Hal Jordan)
Cyborg 
Martian Manhunter
Flash (Barry)
Aquaman

Example is what she did in the AOU movie. No one catches her in the act like Hawkeye did.

A lot of the leagues fears would be similar to Tony's, revolving around failure and causing deaths and what not.

Batman - Falling to corruption and breaking his no kill rule for good, effectively becoming what he hates most.

Superman - Bringing doom to his adopted world, something that came for him and stayed for annihilation.

Wonder Woman - Either being humiliated in defeat or not being accepted in both the human world and her home.

Green Lantern - His greatest fear is fear itself.

Cyborg - Becoming alienated from the human world and disappearing forever into his computerised half.

Martian Manhunter - Reliving what happened on Mars.

Flash - Not being fast enough, that's kind of a big deal to flashes.

Aquaman - A war between humans and atlanteans, resulting in the humans winning and atlanteans being tortured and experimented on. Similar to Thor, bringing doom to his people and all that jazz.
