katori yuutarou

The protagonist of sorts of Taiyou no Yuusha Fighbird, and de facto core of the titular Brave. Katori is an alien who, upon coming into contact with Earth, decides to protect it as part of the Space Police Force.

As an extraterrestrial being, Katori's lack of knowledge on Earth's living beings leads him to mistake a butterfly for a pigeon, sparking a meme.
