Webcomic / Planet B
is a comic strip by DJ Trousdale, centered around four alien friends:
They live in a star system called Astaralgia, which contains 26 planets, each one bearing a letter of the alphabet. Planet A is the "main" planet, and Planet B was the one first colonized. Hex lives somewhere between two cities on Planet B, with Slook as his pet/helper, while Furato lives in a shabby apartment in one city. It's not known yet where RZ lives.
Together, they set out to make the planet (maybe even all of Astaralgia) a better place, sometimes by travelling to Earth to observe what they're doing right or wrong.
