Palpatine vs Thrawn
An Infinities universe where Thrawn rules (With Mara Jade at his side, and ), and Empire crosses over with another universe where Palpatine wiped out the Rebellion and solidified his rule.
Palpatine-verse is based on the movies if Palpatine had won the war, and Thrawn-Verse is basically Zhan's trilogy of books if Thrawn hadn't been betrayed by his personal body guard (Meaning he has the cloning tech, the Noghri on tap, the force repelling alien sloths, and a mad dark jedi clone with brainwashed Skywalkers..)
Both universes Empires become aware of each other, and go to war.
Who wins?
