I'm assuming you swap in "canon" for fandom in this case, lol.

Voltron?

touhou

LoneWolfPrincess Mighty Morphin' Power Rangers but the droids are Oops! All Lions and it's in spaaaaaace.

This is mostly a joke answer since I actually do know most of Voltron/have watched some of it. XD;;

ArchVile Epilepsy the Game: Now with cute anime girls!

This is also a joke answer. XD

Fire Emblem Three Houses?

bunnymoonvii Fire Emblem: Hogwarts edition but with more swords and the Harry Potter gets brought in as a professor instead of a student. Also we got rid of House Ravenclaw because too many brain cells in this game would have avoided the war entirely. ...Also I've actually played quite a bit of FE3H I'm sorry XD;;;;;

But the Blue Lions vs Black Eagles stuff definitely reminds me of the old Gryffindor vs Slytherin rivalries I used to see in fandom spaces in ye olden days

I can't always remember who knows what fandom lol

Dimitri vs Edelgard can get vicious

bunnymoonvii No worries! I just wanted to be upfront about basically cheating cuz I was actually familiar with it. XD;; Good lord can it ever. I'll stick to hanging out in Golden Deer/Hufflepuff town >.>;;

waves the blue lions flag

Gundam Unicorn (or just Gundam in general)

fuzzysquish My Little Pony but they're all robots!

Actual answer: Teens pilot giant robots for some kind of war except it's not the one with Shinji Evangelical.

...you are the second person with an MLP comparison

fuzzysquish Dangit, I should have gone with "Robot Unicorn: Now with new anime flavor!" XD

fffft
