So I'm planning on planing on doing a male reader x fairy tail but I'm having trouble what power will he get so I have two power ideas sound titan slayer magic or color maker magic

Sound titan slayer magic

Color maker magic * sorry I don't have any example for this just imagine it like touhou magic , undndertale magic , or copy other people abilities by just stealing their color but it doesn't give them the same strength

So okay machos and females please vote and comment if you have any ideas I'm all ears so good by machos and females
