simirror

A type of character that appears in the Kirby series. He first appeared in Kirby Super Star.
He looks like a magician and uses his mage staff to create a mirror-like barrier that reflects Kirby's attacks.
Swallowing him would copy the Mirror ability.

At the bottom-left corner of the box art of Kirby Super Star Ultra, Simirror is consistently blocked by age rating icons such as those of ESRB and CERO. This has become a meme among Japanese Kirby fans.
