|First game||Metroid (1986)|
Metroids are one of the major elements and creatures in the Metroid series of games. They are some of the more feared species in the game, as they often appear in dark stages and attach themselves onto your face to suck out your energy.
The species were created by the Chozo, and named them Metroid apparently because the name means "ultimate warrior" in their language.
They created them so that they could be protected from the X Parasite, and they apparently don't eat blood as some may conclude, but rather suck out their victim's life energy. This allows them to kill the parasites without dying.However, their project went awry when the Metroids started to become more vicious and started to attack the Chozo forcing them to leave the planet. Even though it was supposed that the Chozo were killed by the Metroid, the remake of Metroid II: Return of Samus, Metroid: Samus Returns reveal that the Chozo who created the Metroid were betrayed by some of their own and were killed by an unknow masked Chozo warrior armed with a Power Beam canon.
Once a Metroid is born, it considers the first being it sees to be its mother, much like most real life animals do. This can be seen in Metroid II: Return of Samus and Super Metroid, where a newly hatched baby Metroid looks to Samus Aran, the protagonist of the series, as its mother, as normally a newborn would attack her or any other living being. It can thus be concluded that they have a form of intelligence seeing that they have a thought process.
In time, a Metroid will start to morph (the life cycle of a Metroid can be seen to the left) into larger and more powerful creatures. All of the species to the left have been seen as enemies in the Metroid series.
In all, only two Queen Metroids has been found (in the Game Boy video game Metroid II: The Return of Samus and in Metroid: Other M). It seems to be the largest of the Metroid species found in the life cycle above, and currently it is unknown what makes a Metroid turn into a Queen Metroid. The Queen Metroid found in Metroid II is a very strong creature that is capable of tearing its opponents apart easily using its long, expandable neck to grasp onto far away prey.
Metroid Prime (creature)
The Metroid Prime is a creature and final boss in the GameCube game of the same name, Metroid Prime. Apparently, according to the official website at least (which could arguably be considered cannon), Metroid Prime came from the same planet that the Metroid species came from. It was also revealed via the Chozo lore that can be found in the series that Metroid Prime is one of the major reasons why their species started to become extinct.
It should be noted that Prime arrived on Tallon IV long before the events that took place in Metroid Prime. After being defeated by the hands of Samus Aran, the creature was able to regenerate itself and turn into the being known as Dark Samus, who would permanently die in the Wii video game Metroid Prime 3: Corruption.
Involvement with Samus Aran
Metroids play a large role in Samus' life. In the first chronological story, which is also the first game in the series, Samus was ordered by the Galactic Federation to hault the Space Pirate's Metroid production. In all games Samus is often times forced to defeat the Metroids that are attacking her.
As aforementioned, a newborn Metroid (in Metroid II and Super Metroid) assumed that Samus Aran was its mother, and at one point even saved her from Mother Brain once it matured into an older creature.
In the games, if a Metroid starts to suck Samus' life energy out of her, she'll have to go into Morph Ball mode and bomb the creature off of her, though that doesn't entirely mean it will die. Usually Metroids are hard to defeat, taking multiple shots, sometimes even many missiles to ultimately kill. In Metroid Prime 3: Corruption, they could easily be defeated when in hyper mode. In side-scrollers, they could only be killed once frozen, where Samus will then have to shoot the Metroid which is trapped in ice.
Types of Metroid
|Alpha Metroid||The second form of a regular Metroid. The top, bluish glowing part of a regular Metroid seemed to have gone down to his underside. Also spawned legs, which allow it to walk around. Once a Metroid turns into an Alpha Metroid, it looses its ability to grasp onto its opponents.|
|Gamma Metroid||The third form of a regular Metroid, and the form that an Alpha Metroid turns into. While not vastly different from the Alpha version, it is larger and more vicious, and also has bigger horns.|
|Zeta Metroid||The fourth form of a regular Metroid and the form that a Gamma Metroid will turn into. It's about the size of a human, though a little taller. Arguably it could be considered the biggest change in all the forms that a Metroid goes through.|
|Omega Metroid||The fifth form of a regular Metroid, and the form that a Zeta Metroid turns into. Much larger than a human, and in appearance looks like a dinosaur. When a Zeta Metroid turns into this form, it is not only more powerful, but it also gains the ability to shoot fire balls from its mouth.|
Super Smash Bros. series
In Super Smash Bros. Brawl, the Metroid is an Assist Trophy. The form it most resembles is the Zeta Metroid. When summoned, it floats around and targets a nearby opponent and attacks to them with very light damage and stuns them repeatedly restricting their movement. Eventually, the Metroid comes off and sometimes attacks another opponent. If not, it will just disappear. In the trophy, the reflection of Super Metroid can be seen on it.
In Super Smash Bros. for Nintendo 3DS and Wii U, it returns as an assist trophy.
Super Smash Bros. Melee
- A parasitic life form that can absorb all types of energy, Metroids have strong resistance to most conventional weaponry. To defeat them, Samus Aran had to freeze them with Ice Beam shots and then blast them with missiles. Mochtroids, which look like Metroids, are weaker, with fewer internal nuclei.
Super Smash Bros. Brawl
- A bioengineered life-form found on planet SR388. Metroids attach to organisms and drain life energy. The Galactic Federation commissions Samus to eliminate them, but Space Pirates try to harness their power. One of the few ways Samus can kill Metroids is by shooting them with the Ice Beam and then shattering them with missiles. The Metroid's cry is chilling and indescribable.
Super Smash Bros. for Nintendo 3DS and Wii U
- EU:Mysterious floating life-forms, discovered on the planet SR388, that absorb energy from other living beings. They're tough, except when they're cold. In this game, they'll try to attach themselves to fighters' heads and drain their energy. Press all the buttons you can to shake them off!
- NA: First discovered on planet SR388, this floating life-form grows by absorbing energy around it. It is incredibly durable but extremely weak to cold. In Smash Bros., a Metroid will grab a rival by the head and drain energy. If you get grabbed, shake it off by pressing left and right!
