Torizo

From Wikitroid, the Metroid wiki

"Torizo" is a term used to refer to "living" Chozo Statues. According to the Chozo Lore "Statuary", some specially infused Chozo Statues can exert their influence to defend artifacts and serve as sentries. The Torizo are often misunderstood as either evil Chozo or robotic copies.

There are five Torizo that are specially noted in Super Metroid: The "Bomb" Torizo is the first, found in Crateria. It tosses bomb-like objects at intruders. Samus Aran battles it within minutes on the planet. At first it appears as a normal Chozo statue holding the Bomb upgrade, though when she grabbed it, the statue broke apart and the Bomb Torizo rose out of the rubble. To defeat it, Samus had to shoot at its chest with her Power Beam and Missiles. It continues fighting even after its head is destroyed. It is very weak, as even the uncharged beam can damage it. Missiles also inflict significant damage to it.

The second one is located in the Wrecked Ship, though this most likely is a statue than it is a living Chozo.

The third Torizo is found in the depths of Norfair that controls the acid level. The same may be said as that of the previous Torizo.

The fourth Torizo is colored gold and Samus encounters it in Ridley's Lair in Norfair. Compared to the Bomb Torizo that Samus encountered earlier in her mission, the Golden Torizo is stronger and more intelligent. As well as being able to spew fireballs and energy waves at Samus (like the weaker version), it can also use boulders as weapons. Normal Missiles are mostly ineffective against the Golden Torizo, who will simply turn to the side and dodge them, though with timing they can still damage it; Super Missiles are not entirely effective either, as the Golden Torizo usually grabs them and throws them back at Samus, however it can only hold one Super Missile at a time so a barrage of missiles could damage it. The charge beam is also highly effective and the Torizo cannot grab a charged shot. The color starts out gold, but gradually gets duller until it is colored brown much like the original Bomb Torizo. Upon defeating the Golden Torizo, Samus will be rewarded with the Screw Attack.

The fifth is located in Tourian, but crumbles to a pile of dust, most likely due to the Metroid hatchling siphoning its energy.

A Torizo can also be seen walking around the Brinstar stage of Super Smash Bros. Melee and Super Smash Bros. Brawl.
