DCEU: Where was Wonder Woman when the kryptonians invaded the earth ?

Probably vacationing in the Caribbeans.

Perhaps she was on Themyscira (no Wi-Fi, phones or TV;), so she missed all fun.

Lol.

Smashing the pool boy in a resort in the Caribbean.

Not in Metropolis

Diana was in Europe.

in france

There was no early plot/story prepared for her, simple as that.

This is about the same as asking what were the people in Kamar-Taj doing when the Avengers were trying to defend the Earth from Loki's army in 2012, or where the Avengers were when Thor was struggling to stop the Dark Elves' plan to destroy the universe.

She was either in London or Themyscira

And here I thought I was sick of these threads regarding the MCU - now we have DCU ones.

She was inspiring humanity as per the shit retcon.

Hanging out with Flash and Aquaman.

She was trapped by Schrodinger at the time.

Doing nothing very interesting

Probably out shopping.

QFT

On the other side of the Atlantic probably.

Smiling

Filing away museum paperwork apparently.
