The list I got of possible costumes for Zintiel this round was:
*Nintendo's Luigi
*A magic user from any video game
*A gijinka/costume of a fruit or vegetable

I'm not big on fan stuff to begin with, and Zintiel (this version) being from not-Earth -and- from the future limits what she would be familiar with. That leaves fruits and vegetables. I still hate that word, "gijinka"... why not just say anthropomorphic like normal people?

But anyway! At first I considered... what fruit/vegetable is purple, so Zintiel's hair wouldn't be out of place? The answer, eggplant. Which led me to think of... Eggplant Wizard, a magic-user from Nintendo's Kid Icarus video game... ... 2.5 out of the 3 costume prompts! That tickled my fancy, but because of the reasons above, I wasn't sure I wanted to go with that.

Eventually, I thought of dragon fruit. That is one badass, spiky fruit. And the result is what you see here.

Any reference to a video game in this final picture is purely coincidental.
