As for Abilities/Powers-
Static abilities consist of the other Static beings, like a hivemind he is able to control, see, and hear through them and also is able to nullify or enhance the Static/Decaying effects. ( He's the only conscious Static being which gives him the ability to control others who have become like himself. )
His Ink-like blood can be taken in to have Static/Erroring/Decaying Effects nullified. ( it's actually incorporated into the Patches, but we can't let the majority know that )
As for Marker's abilities- he is one who instead uses his markers to give himself emotions or attacks, he gives them to others instead! If he does want to attack however, he lets his scarf ( also known as Scarfy ) take in the Ink and create defensive or offensive attacks. He's a protector, a pacifist.. I don't think he'd exactly attack anyone unless he believes there's no coming back for them ( and it's really hard to make him think that. )
Edit: Marker has Emotions from the one piece of Statics soul that he absorbed, and has a artificial other half made, so he doesn’t need to eat Ink/paint. it does give him a boost, but he’d rather help others with it!
