I'll post something about original project later but for now allow me to introduce some Tetris OCs that I am working on!

The StreetMinoes would be 7 different characters with heads of Tetriminoes, each with their own personalities, culture and skills.

Leslie is the cheerful tour guide of LeisureLand that strives to make Leisureland more and more entertaining.

Ivan is the CEO of one of the start-ups in Ideapolis. He has a bright mind but slightly bad time management.

Terrence, former builder of the Tetribots in Technozone, is stoic and inexpressive on the outside, but on the inside he is caring and focused with his inner thoughts.

Otheus is a greedy man who read a lot of stories about Arabian Nights, and living in a very lowly developed desert area, he dreams of turning Oasia as developed as the Arabian Nights while holding many (fortunately morally correct) activities that nets him cash.
