Story idea (oneshot) Botany Bay slips through an interdimensional vortex and ends up in the B5 universe.

Aboard Babylon5, Khan becomes something of a legend before the urge to conquer overcomes him...

Use lines:

He even won a drinking contest with a pak'ma'ra much to the horror, disgust, and awe of the surrounding spectators.

Khan briefly gets control of station and Captain Sherridan comes up with an novel solution to deal with him.

"I think it's time to introduce them to our 'superior race'." the captain said from where he watched Khan on the monitors.

"Captain, you can't be serious!" Ivanova exclaimed.

"I am, now raise PsiCorps before I change my mind."

Last line of the fic:

Superior my ass. Bester muttered as he exited the captain's office, not sparing a glance for the drooling wreck he had left behind him.
