Kraid (or in Japanese クレイド Kureido) is 3 eyed dragon that resides in his lair conveniently named "Kraid's Lair"Kraid's Debut was in the original Metroid Released on August 6, 1986 in the original Kraid is the first boss you face although he is not as big as he is in Super Metroid onward.

Kraid, Surprisingly, is not from Zebes besides that his home world is unknown.

STRATAGY

METROID: My recommendation is to fire Missiles when his back is turned and always destroy the nails when you have a chance

(Beam: Ice beam is most useful)

SUPER AND ZERO MISSION

shoot a normal shot in his eye then unleash Super missile havoc into his mouth

If your playing Zero mission then do the same except with normal missiles

Tip: If you run out you can attack the nails to replenish on health and missiles

TRIVIA
 * Kraid was planned for Metroid prime this can be seen from a piece of artwork, The artwork makes Kraid look more metallic similar to Meta Ridley so fans dubbed it 'Meta Kraid'
 * In Zero mission Kraid doesn't have the full tail this is proven when you look at the Pirate's Sprite this does make sense because You (Hopefully) wouldn't be able to get behind Kraid in the final version


 * According to the official Metroid: Zero Mission web site, Kraid is over two stories tall, the low-end being three stories. This would mean Kraid is 9.9 meters tall (32.5 ft.), nearly half of his height in-game.
 * The color of Samus' suit during the cut-scene with Kraid rising before her in Zero Mission will vary depending on whether or not the Varia Suit is acquired prior to the battle.
