This is Marian von Charlottenburg's (sweet name!) triforce arm tat by Needlefak (no thank you!) Tattooing in Hamburg, Germany. Not gonna lie, at first I thought it was a Photoshop job, but I just spent upwards of ten seconds comparing the two photos until I realized I didn't care and I was going to post it anyways. Standards: mine are incredibly low.
Thanks to Stacey, who wants to know what the invisible triangle in the middle of the triforce stands for. It's a secret to everybody (See what I did there?!).
