So, I have a few headcanons about Theo involving his appearance, and I find myself thinking every time, "Kurt's gayness intensifies." So...
To start, Theodore's hair goes to his shoulders, right? Mine has gotten that long, and I can tie it into a little ponytail when I want it off my neck. What if Theodore did that in the summer?
And as a bonus, they've kind of changed their clothes (mostly Theo) to beat the heat. This is my first time drawing Kurt, and I'm honestly not surprised that I didn't give him a serious shot.
The next one involves the idea that in every Beyblade-based universe where he's a good guy, Theodore is a Blader. Like all Bladers, he trains as hard as possible to get stronger. Even now that he's a Beyblade manager, he still keeps up his routine. How else will he be able to determine if the trainees of the Snake Pit can handle the exercises?
He's not rippling muscle like Kurt himself or Xander, but Theodore isn't a twig, either.
(And clearly, you can see how I take Kurt very seriously. -Sighs and mutters- I made him look like a dang Muppet.)
