itch.io

Uses two-dimensional "sprites", 2D images created and used on a flat plane, as opposed to the three-dimensional models or environments found in 3D games.

Provides tools that let you customize characters with either free form sliders or combinations of pre-made options.

Graphics for creating characters

Set in a fictional universe, often (but not always) with fantastic or supernatural elements, alternate worlds, magic and monsters.

Pretty sure everything is indie on itch.io but just in case you want something extra indie.
