If you want to get a fandom tattoo go for it, but don't just slap an image from google straight on your body cause that will most likely come out looking cheap or straight up bad.
Best advice I can give you is discuss it with your tattoo artist before doing the tattoo. And I don't just mean 10 minutes before doing the tattoo. You should have a meeting where you present your ideas and then discuss the possibilities together, maybe ask for few sketches and such.

As a side note, i wouldn't suggest putting it anywhere bellow t-shirt sleeve unless you are absolutely positive that you don't mind anyone seeing it and making assumptions about you, because it will happen.
