if pokemon could watch tv i think it'd be a headcannon that marley gets inspiration from my little pony- like, to the point where she takes every friendship lesson to improve her own self; which is technically a good thing? she even has her own little trixie plushie that she hides in her tail i swear it's adorable jsjsksisjsjw ("oh hobbes! her story of villainy and redemption, it's just like your attitude towards me!") she tried lending hobbes her IDW comics but he was more interested in Animal Crossing and Doom crossovers.
k i should probably stop rambling about noncanical headcannons
