Fun tidbit: The binary code in the background of Mastemon isn't just random nonsense. It's the American Digimon theme song. I used a translator, though, not like I know binary code or have the patience to translate it.
I forgot but I did draw some Digimon before. One is stuck on my 3DS from Pokémon Art Academy because of course I drew Agumon when told to draw Charmader. Anyway, here are the ones I do have saved. Palmon driving a go cart and Mastemon. Anyway Enjoy:
I've been playing Digimon: Time Stranger! I'm really far in now, just unlocked Megas. Soon... soon Shine Greymon will be mine. He's just taken a slight detour.
.hack, Digimon, Yugioh! Arc 5, .hack again for some reason. Pretty sure there is a visual novel or two with a main character named Sora, but I just remember seeing that in passing. Those are the ones I can think of off the top of my head.
I have all the Rookies but I am missing one In-Training. Botomon, I think.
Something I like doing is going as far as I can with a line and then go all the way back to the first stage, trying to go in a completely different direction. Definitely a thing I did with Devimon and Lilithmon.
