Trident Knight

Trident Knights are members of the Meta-Knights. They wear armor that is usually purple in color, sporting a moon crescent as seen on Feudal Japanese armor, with red shoes. As its weapon, it carries around a supply of tridents which are electrifying to the touch. They currently serve under the order of Meta Knight.

Kirby's Adventure and Nightmare in Dreamland
Trident Knights are one of the four Meta Knights that serve as a recurring mini-boss. Once Kirby enters a certain room, Meta Knight makes a command before disappearing, and his minions appear. The Trident Knight simply sits upon a ledge and tosses tridents at Kirby. These fork-like objects are electrified. Even so, neither these nor the Trident Knight give Kirby any ability. The Trident Knight will either appear or run in from a side of the screen.

Kirby Super Star and Kirby Super Star Ultra
Trident Knight behaves the same as in previous games, but appears without the requirement of Meta Knight's command. Alongside its usual Trident tossing, it also has a new form of attack: it can jet at Kirby, attempting to stab him with the trident currently in his hand. Trident Knights are also summonable by Galacta Knight, these being dark purple and sea green in color.
