Made a proper ref sheet for Dart, my Ultraman oc based in my Fuwa Ultraman plushie! The plush very round (it actually can't sit down very well because of that) so I made Dart fat to reflect that. Also because there should be more fat superhero ocs.
He works as a teacher on his home planet, CM78. It took a while for him to adjust to Earth after accidentally flying through a warp hole due to how violent Earth is compared to CM78, but with the help of human friends he quickly adjusted, and can throw quite the punch.
Fuwa Ultras are I guess a fan Ultra type? They're based on the Fuwa plushies obviously but more specifically inspired by Ultraman Theater Love And Peace, which is a short animated film. It's very cute and I fell in love with it and thought a little too hard about the Seabozu that landed on the planet in the final act that shrunk down to the same size as the other Kaiju and Ultras at the end because to me it implied that this was it's own planet and everyone was just that size naturally, but the typical giant Kaiju and Ultras also existed, just not on the planet the movie takes place. Fuwa Ultras in their default form are quite small, to the point that when Dart first ended up on Earth he was mistaken for a child (which he quickly corrected), and have a unique feature of teardrop shaped crystals on their heads and fur that varies in length. They also can sustain their Ultra size longer than most other Ultra types since they don't rely on light energy as heavily and instead how long they last is determined by their stress level (think Ultraman Rising). They can also revert if they become exhausted though. Their culture is very peaceful, as Planet CM78, also called The Planet Of Love And Peace, has only ever experienced one war which was also the one and only time they were invaded. It turns out the tiny Ultras, even when scared and with no training, hit like a freight train. Dart's experience on Earth has allowed him to become quite skilled in fighting and maintaining Ultra size compared to most other Fuwa Ultras born post war, though at the end of the day he is still considered a civilian.
I know he technically isn't a Kaiju and would actually be considered a Seijin (which roughly translates to "People of Planet (INSERT PLANET HERE)") but there's no tag for that and alien doesn't feel quite right. Plus Ultraman is a Tokusatsu series that heavily deals in Kaiju so it still kinda fits.
