The Metall (メットール,Mettōru?), often called "Met", is an industrial robot that appears in Guts Man's stage. It sits on the floor hidden in its indestructible helmet, and when someone gets close it lifts its helmet and shoots three diverging bullets.
They also appear in Mega Man: Powered Up. On Easy mode, Mets only shoot a single bullet forward. Strangely, the bullet that is shot diagonally down is never seen in the game, as it always hits the piece of land the Met is sitting on. Comically, Mets can be flipped over onto their helmets by hitting them with a Proto Strike, with a second level charge shot, detonating a Hyper Bomb next to them or hitting them with the Oil Slider. The Met will then continue to rock about on its helmet, where you can easily shoot it or leave it to its own devices.
The Metall DX (メットールＤＸ,Mettōru DX?, Metall Deluxe) is an upgraded version of the Met that appears in Mega Man 3. Most of the Metall DX act similar to the Neo Metalls from Mega Man 2, but there are some that have retractable propellers in their head that allow them to fly. They fly up to Mega Man and shoot three bullets down on him. The Heli Metall from Mega Man 7 is similar to this Met.
They also appear in both Buster Rod G's Stage and the 3rd Wily Tower Stage in Mega Man: The Wily Wars.
The Giant Metall (ジャイアントメットール,Jaianto Mettōru?) is a sub-boss from Mega Man 3 that can shoot giant bullets and throw out three regular Mets. It can only be hurt on the red "+" mark on its helmet. Search Snake and Hard Knuckle are the weapons that cause most damage to it, but they are not easy to use against it. Two Giant Mets appear in the Doc Robot Needle Man stage, but if one looks closely in Needle Man's proper stage (before the Doc Robot reprise), one can see the helmets under the platforms.

Metall EX (メットールＥＸ,Mettōru EX?) is the name used for all three types of Mets in Mega Man 4 (walk, jump, and spin), but the spinning Met is also known as "Metall Dance" (メットールダンス,Mettōru Dansu?) in RockBoard. The first two Met versions act similar to typical Mets, walking or jumping after shooting, but the Metall Dance does a sort of ballet spin that shoots three shots in a row, straight out. It takes three normal shots or one charged shot from the Mega Buster to take a Metall Dance down.
Metall Daddy (メットールダディ,Mettōru Dadi?) is the first boss of the Wily Castle in Mega Man 4. This Met can jump to where Mega Man stands, and when it lands, it makes four normal Mets fall from the top of the screen. It is weak to Ring Boomerang and Dust Crusher. The Powmettaur from Mega Man ZX is similar to this Met.
The Space Metall (スペースメットール,Supēsu Mettōru?) is a type of Met equipped with jet packs to chase enemies. Because of this, Space Mets are unable to shoot and hide into their helmets. They appear in Star Man's Stage in both Mega Man 5 and Mega Man for the Game Gear.
Metall Mommies (メットールマミー,Mettōru Mamī?) explode and give off three Baby Mets when shot. Found mainly in Stone Man's stage (in Mega Man 5, Mega Man IVandMega Manon the Game Gear), but they also appear in the second Wily stage. Gravity Hold can easily defeat them; it will cause Metall Mommy to explode, and then the Baby Mets will immediately fly off the top of the screen afterwards.
Metall K1000 (メットールＫ－１０００,Mettōru K-1000?) are Mets that ride locomotives. They, like all Mets, can only be hit when their eyes are in the open, but they also shoot and "toot" and charge toward Mega Man. The safest place is just above or just below them. Very appropriately, they are located in Charge Man's train level, but also in the second level of Proto Man's Castle.
The name may be a pun: sen is Japanese for "line/rail" as well as the number 1000. Keisen is Japanese for "track." Kilo is also Latin for 1000 and frequently abbreviated to K, so from keisen we can derive K1000.
The Metall Cannon (メットール砲台,Mettōru Houdai?) is a cannon with a Met operating it. The cannon fires large projectiles, and the operating Met can only be hurt when it pops its face out. Appropriately, they appear in Napalm Man's stage (in both Mega Man 5 and Mega Man for Game Gear), but they also appear in the second and third sections of Proto Man's Castle and the first section of Wily Castle.

Metall Sniper (メットールスナイパー,Mettōru Sunaipā?) is one of the Mets of the Stardroids from Mega Man V, and it has a gun on its helmet (unlike the previous ones, which basically shoot when they rise, and the player does not see where it shoots from). There is a similar enemy called Fukuhorn.
The Metall Potton (メットールポットン,Mettōru Potton?) dispenses two types of Mets. It has a whole array of them stashed under a dome and drops them out one by one. Metall Pottons appear in Tomahawk Man's stage and in the final section of Wily Castle. This Met makes a cameo in a stage in Marvel vs. Capcom.
Metonger Z (メットンガーＺ,Mettongā Z?) is the boss of the third Mr. X stage, and located in the boiler area's main boiler room. Its attack alternates between straight shots and bouncing bullets. The weak spot is the Met in the cockpit, and the best weapon is Blizzard Attack. It is based on the super robot Mazinger Z by Go Nagai.
In the first three Mega Man Zero games, the player can use Cyber-elves to turn some aerial enemies into "Heli Metall RW". Those Mets act similar to the original counterpart, except that when hit in the propeller they will fall and act as normal Mets.
The Fire Metall (ファイヤーメットール,Faiyā Mettōru?) are Mets dressed up as Fire Man. In Mega Man 8, they first appear in Grenade Man's stage, and they tend to be the ones who set ablaze the big boxes of dynamite in the second half of said stage. They also appear in the first stage of Dr. Wily's castle, after the conclusion of the sledding portion. In Mega Man & Bass, they create flame spires and have treads rather than feet. In Mega Man & Bass they appear in the museum stage, Dynamo Man's stage and in the final stages.
Cactuspy, known as Sabotall (サボットール,Sabottōru?) in Japan and Sabottol in some sources, is a Met wearing a cactus that appears in Mega Man Powered Up. They were designed for desert regions, but unable to bear the heat, they started to wear cacti on their heads to keep cool. They also have poor work ethic and tend to wander off a lot.
Cactuspy attack by shooting five thorns in different directions, although on Easy mode they won't shoot at all. Their Japanese name is a combination of the words saboten (cactus in Japanese) and Metall. These spiky robots can be found in Oil Man's stage. Burning them with Fire Storm will destroy their "hats" and expose them.
The Metall β (メットールβ,Mettōruβ?) appears in quite a few stages in Mega Man 9. Its "cousin" is the Camouflametall. It looks and acts exactly like the Met from the first Mega Man game. Black Hole Bomb and Tornado Blow are two of the few weapons in the original series of Mega Man able to kill Mets even when they are hidden under their helmet.
Camouflametall (カモフラメットール,Kamofuramettōru?), its name being a combination of camouflage and Metall, and often called the Fake 1-UP, is encountered in Wily stage 3 and Special Stage in Mega Man 9 and is a very common enemy in Superhero mode. It behaves like an ordinary Metall, but is disguised as a 1-up, and bullets shoot through it to trick players even further. Its color depends on the current weapon of Mega Man, and its design even changes in the case of if the player is Proto Man.
Neo Metall X (ネオメットールX,Neo Mettōru X?) is a variety from Mega Man 10 that acts similar to the Neo Metall from Mega Man 2. They appear in Commando Man's stage, Wily Castle 1, Wily Castle 2, Special Stage 1 and Special Stage 2. They also appear in the stages of Blade Man and Nitro Man in Hard Mode. Their indestructable hats cannot be knocked off.
Neo Heli Metall (ネオヘリメットール,Neo Heri Mettōru?) is a flying Met from Mega Man 10. They fly in place and stay inside their helmets, appearing at times to attack. They appear in Nitro Man's stage, Wily Castle 3 and Special Stage 2. They also appear in Wily Castle 2 in Hard Mode.
Numetall (ヌメットール,Numettōru?) is a slug-like Met from Mega Man 10. They release three destructible balls of sludge that stick on the player, causing them to slip and slide as if they were on ice. The balls can be destroyed when playing as Mega Man by using the Solar Blaze on himself. They appear in Pump Man's stage, Wily Castle 1, Wily Castle 3 and Special Stage 1. On Hard Mode, they also appear in Wily Castle 5 and the effect of the sludge-balls lasts longer. Its name is a combination of Metall and the Japanese word "numetteru", which means "being slippery". They are also better at hiding under their helmet than normal Metalls.
In the computer games Mega Man and Mega Man 3, the Met's helmet is red, and its health points are higher than other Mets.
If the player chooses the left path after defeating Snake Man in episode 2 of Super Adventure Rockman, Mega Man will find a Met family dining. Two of them are probably the Metall Mommy (right) and Baby Metall (small) from Mega Man 5. Mega Man does not fight them. Both paths leads to the fight against Needle Man, but this scene is skipped if the player takes the right path.
In episode 3 of Super Adventure Rockman, Mega Man finds a Met with arms carrying an item box after the defeat of Magnet Man. The Met will get scared and run, leaving the item box behind, and the player has to choose between three options: fight against the Met, get the item with data about Ra Thor, or ignore both and continue. If the player chooses to fight it, it will appear without arms and attack by shooting six times while spinning, and hit Mega Man with its head. After its defeat, two medical Mets will appear and carry the Met away with a stretcher. All three options are followed by the fight against Hard Man.
