First Come, First Serve

Fry - 'You look like us but more better! Why?'

Leela - 'A good question, stupidly asked.'

Bender - 'What are you? Some kinda parallel universe versions of us? Because frankly, that's been done to death!'

Sheila, Mender, and Sly.
Then alot of crazy stuff happened but, I best not reveal too much.....They appeared in the comics.
