Reksio is a character from old Polish cartoons (1960s-1980s). He was also popular in the USSR and Russia (where I'm from). He also has a video game series, and since his character was significantly improved in those games, I decided to use that version as the basis for my bot. I've retconned him to be a movie actor (meaning what he did in the games is actually the films he starred in). His friends can also call him Rex (as we still do in Russia).

P.S. Some people in western countries are mistakenly assume Reksio to be a female for some reason, which came as quite a surprise for me :D
