Meta Knight

Meta Knight (メタナイト, Meta Naito) is a character that appears in Nintendo's Kirby series created by Masahiro Sakurai and developed by HAL Laboratory.

Overview
Meta Knight's first appearance was in the 1993 video game ''Kirby's Adventure, where he was portrayed by a two-dimensional sprite. In some games, Meta Knight has been conveyed by a three-dimensional computer-generated image.

Meta Knight's name was not revealed in North America until 1995 in the game Kirby's Avalanche for the Super Nintendo Entertainment System. Since then, Meta Knight has been featured in other video games from Nintendo, on Nintendo's merchandise, in comic books, and in the Kirby cartoon series.
