SO

red paladlin: umbra
blue padalin: aunora 
yellow padalin: matthew
green padalin: seraph
black padalin: victor
alteans: esper (prince) and salvador (advisor and definite Weird Uncle)

victor was lost and presumed dead in a mission to space, where he gained a prosthetic arm and a skunk stripe. umbra saw victor as a little brother and was heartbroken when he was lost. (reverse of shiro and keith tbh)

esper and sal awaken from their cyropods and are very concerned when the black lion chooses a little boy bc holy crap. aunora believes in him tho...tho shes still riding on the "right about aliens" thing soooo

later, esper takes upon the role of pink padalin.

pilate would probably be lotor? because thats just funny as all get out. arisha, hawkins, and asher would be his battle harem
