Pararoid (パラロイド?) is the strange dragonfly-like enemy in Morph Moth's stage and Agile's stage in Mega Man X2, two of which enter into large Mechaniloids in the former's stage. Destroying the Pararoid destroys the mechs as well.
There are three types in Mega Man X2: S-38, V-1, and R-5, according to the end credits.
Types of Pararoids
Pararoid S-38, alias Metaroid, is a specialized Pararoid that inhabits large robot bodies (Old Robots) and serves as a mid-boss for Morph Moth's stage twice. One was locked away in a capsule after causing trouble in the junkyard when it was still in use. There are two of them. They are weak to several weapons, such as Bubble Splash and Spin Wheel. Additionally, Sonic Slicer, Speed Burner (if fired on the ground), and Giga Crush will destroy the S-38 instantly.
Pararoid R-5 is a winged non-boss Pararoid variety. They fly forward up and down and then attack by trying to ram X.
Unlike the R-5, the V-1 variety are wingless, but they hop about and try to latch on to X's head to either force him to rapid-fire as fast as the game can manage (sometimes quite useful), jump repeatedly, or dash repeatedly.
Pararoid Jumbo (パラロイドジャンボ?) is a bigger winged Pararoid from Mega Man X5 that can cling to ceilings and shoot missiles. It appears in the stages of Dark Dizzy and Mattrex. This type of Paranoid can fire a missile from its body, or fire a short laser beam from its mouth. It's weakness in Mega Man X5 is Tri-Thunder (X) and E-Blade (Zero), although it will take more than one of such attacks to be defeated.
Pararoid (Command Mission)
The Pararoid that appears in Mega Man X: Command Mission is a winged blue Pararoid. They have a very high dodge rate and are able to execute "Parasite," an action where they destroy themselves in order to maximize the Power, Armor, Shield, and Speed of another enemy on the same battlefield. They appear in Gaudile Laboratory. A broken Pararoid can be found in Vanallia Desert and repaired to be used in the Deployment Center.
Metaroid is a highly fast red Pararoid variety from Mega Man X: Command Mission and also have a very high dodge rate that always starts the battle with "Parasite," destroying itself in the first turn. The only way to attack or steal the rare Brave Buster against them before it uses Parasite is having the Force Metal Cutting Edge equipped. If there is no ally in the battlefield to use Parasite, it will run away. They appear in the Far East HQ.
