This is a challenge for anyone who wants to write it.

The challenge is a Ben10 mass effect crossover, that is what the Mass effect universe would be like if Humans didn't exist and instead Pyronites ( Heat blast's race) existed instead of Humans.

Rules

The story must begin with the first contact war between Pyronites and Turians and by that I mean the very beginning of the first contact war when the Pyronites discover relay 314 to the invasion of Shanxi ( it would be interesting to see Pyronites fighting the turians) to the end of the first contact war when the citadel council intervenes to negotiate a peace.

The story then has to go on to the events of Shepherd's life starting from his childhood ( NOT his entire childhood just some clips from it) and to the events of the Mass effect trilogy

There are some rules regarding shepherd

Shepherd has to be male

Shepherd has to be Pyros born ( since Pyronites replace Humans, Pyros replaces Earth) he was an orphan raised on the streets of the megatroplises covering the planet like sun of Pyros, he escaped the life of crime and underworld gangs by enlisting in the military when he turned 18

Shepherd has to be paired with Tali

That's pretty much it, his class and psychological profile are up to you.

Anyways like I said this story is supposed to be what the Mass effect universe would be like if Humans didn't exist and Pyronites replaced Humans, so it would be nice for the story to show what the Asari and the other races of the citadel think of the Pyronites.

And remember the events of the mass effect trilogy must also be shown.

That's pretty much it for the rules all the other events are up to you.

If you choose to write this let me know please, either by review or PM!
