Roleswap AU: Altean!Holt Family, human!Allura... I found this buried in my drafts from before Romelle was even on the show.
Have some old edits of Pidge and Matt.
10,000 years ago, King Samuel and Queen Colleen sent their children from Altea so they would survive, just in case Zarkon managed to destroy the planet. Matt was sent with Coran to Arus, along with a puppy called Bae Bae.
Katie was supposed to reach one of the Altean colonies, but for some reason, she didn’t. It was for the best, as they were destroyed at around the same time as Altea. Instead, she crash-landed and woke up many years before Voltron would return.
A year before Voltron’s return, Shiro is on Kerberos, along with Commander Alfor Brooks and his niece Romelle. Alfor’s daughter is currently studying at the Garrison in Astrochemistry. When she learns of the crash, Allura begins to look into it and barely manages to not get kicked out of the Garrison.
She has four pet mice at home, and wants to find her dad and cousin and defeat Zarkon before they die. They’re currently in Bandor’s care.
On the night of them finding Shiro, Lance follows Allura because he thinks she’s cute. Hunk really wishes that Lance would not do this because they always get in trouble and hey look, now they’re committing treason
Keith recognizes Allura because she helped him find out about Shiro. He still doesn’t remember Lance, though.
When the group meets Matt, both Allura and Shiro mentally call dibs.
Allura pilots Blue, Hunk Green, Keith Yellow, and Lance Red.
Rolo and Nyma initially prepare to lure in Voltron and steal one of the lions when they see Matt. Suddenly, they realize that they have to do the right thing, if only for the fourth (and simultaneously both oldest and youngest) member of their crew.
“Hey, Pidge?” Rolo calls. “You should really come see this.”
“Can’t I just make sure we have stuff for the co- I mean, the thing we’re doing?”
“This guy looks a hell of a lot like you!”
Matt’s baby sister is supposed to be a child, the Altean equivalent of an eleven-year-old. She’s not supposed to be an angry looking adolescent smuggler who grew up without him. Then again, she’s also supposed to be dead, and she isn’t.
