Lubi

Lubi is my mascot, and more of an expression than he is a character.

He doesn't have a distinct personality beyond being happy and lively, as his main function is simply to be fun to draw.
He has no colour palette and his design is flexible; as long as he stays recognizable, he can be simplified or redesigned at will.
The four core characteristics of his design are the heart mask/face, heart on his chest, flame hair and tiger stripes (usually on his legs).

Lubi doesn't speak and only communicates through charades and expressions.
