Didn't know Lotor had a sister? Neither did the rest of the Galaxy until recently!! Boy were the Scribes surprised to learn that not only does he have a older sister, but his mother is still alive. Both are little known facts, that has been closely guarded from Hagger and King Zarkon.
Devana is actually his half sister, from his mother side, but he loves her dearly, maybe even more so, since she has none of Zarkon's tainted blood flowing through her veins. That's right, she's not of the Drule face, but a human variant. We have yet to learn who her father could be, but it's certain it's where she got her ash colored hair from! (I've heard rumors that he's a big shot Admiral in Galaxy Garrison!)
A semi-official Princess, her favorite pastimes are making Princess Romelle's life miserable, and spending lot's of quality time with Sven. You could say the two combine, since Romelle has her eye on the handsome former Blue Lion Pilot! Devana and Romelle have tangled quite a lot recently over the handsome pilot, with Devana trouncing Romelle quite royally! Unfortunately, Romelle finally found a prince to marry...whose almost an exact twin of Sven, except for one certain...*Ahem* body part! *Wink* Prince Stefan...who seems to be in a perpetual state of lust after Devana, wanting to make her the first member of HIS harem. And he won't take no for an answer!!
Devana also enjoys driving Princess Allura's Nanny nuts. What's a sister of Lotor doing, hanging out with Allura and Company? Why it's simple! She's a Voltron pilot, called in to replace Allura, since Coran and Nanny decided piloting was too dangerous for the princess. But it just posed another problem for Nanny. She thinks Devana is a bad influence on Allura, making the princess more willful and independent!! Devana's words? "Well it's about time someone did!!"
She also seems to have an influence over the rest of the V-force, making the guys even more mischievous than normal! Yet pranks galore abound in the Castle of lions, making poor Nanny practically tear her hair out from outrage!!
