As a denizen of the sky, Thundurus is pretty fast. A lone plane was unfortunate enough to stray into their territory. They have no problems catching up to it, especially not after becoming so massive!
Thundurus-T: They/them
You know how I've been saying "I need to stop shading these"? So... i did that, and then out of nowhere I was bodied with the itch to PAINT the background. I don't paint. I'm primarily a cartoonist type of illustrator. I don't know where this came from, and I ultimately had to redo the clouds from the ground up due to impulsively adding the ground, mountain range, and setting sun and thus screwing up the light source. Basically I did everything except shade the subject. So TECHNICALLY I didn't shade it. Technically.
Truth be told I pulled this one to be the 13th day, but the amount of time It was taking forced me to bump it back. I'll be scaling back quality to get Poketober done this century, I'm sorry ;_;
