These are different Links and important items to the seirise; triforce, sheikaslate, golden harp, and the master sword. Midnas' helmet is in botw dlc so drawing botw link with Midna seemed like a fun idea. Twilight Princess Link didn't quite turn out how I wanted it though... at least Skyward Sword Link turned out OK.
