After a really strange set of circumstances, the bashful Erys became an illustration of herself, bound to walls and floors as paint. Despite her fluid movements, she is pretty dry, never leaving a stain in her wake. Her being-not-exactly-normal brought a lot of unwanted attention to her, but it allows her to hide quite easily.

Being stuck in two dimensions may seem rough, but it's not that bad. She can show you! (well, not you, but non-paint-people in her story)

Her gloves have the unique ability to drag anything and anyone into the walls, as long as said things are pressing against it or completely adjacent. The newly paint-ized things seem to work as they would in a 3D environment, though most living beings find it disorienting. By pushing them out, she can also turn objects back into 3D, as long as they aren't herself. A strategy she often uses is pulling in a painting frame then pulling it out with her still in it, perhaps the closest equivalent of having a way to exist in the third dimension she has.

This ability is merely a translation of what they used to do when they were 3D, but what that was is irrelevant now.

Unlike other two-dimensional characters, she eats and does all those other things normal people have to do to live, with the exception of breathing. She just has to pull in all the necessary stuff into her dimension.

also she hates water
