Pseudoroid

Pseudoroids, known as Falseroid (フォルスロイド) in Japan, are the sixteen bosses in the Mega Man ZX series. They are called Pseudoroids because they draw power from Biometals, not having a strength of their own. The Pseudoroids in the first game are part of Slither Inc., led by the corrupted Serpent. Each of the eight takes control of an operation in one of the Outer Areas.

Mega Man ZX
These Pseudoroids have four different levels for a victory depending on how many times their weak point gets hit during the battle, with Level 4 meaning the weak point was not hit and Level 1 meaning it was hit several times. This determines how damaged the Biometal is if this is the first fight against them. A Level 4 victory also makes a stuffed animal of the Pseudoroid appear hanging in Prairie's room. Interestingly enough, the first letter of each of the ZX Pseudoroids' names matches the letter of the Biometal fragment that each possesses.

Mega Man ZX Advent
Unlike the Mega Man ZX Pseudoroids, who have half of the Biometals of H, F, L, or P, these Pseudoroids have Biometal Ws inside them. Some of these Pseudoroids have a weak point, but it is not as pivotal as the previous game. Instead of four victory levels, there are now three Medals for each Pseudoroid to collect by beating each Pseudoroid in certain ways. They are Gold, Silver, and Bronze, with Gold usually being the trickiest to obtain. It's also implied that the eight Pseudoroids may each be entire species, as the Hunter near the targeting range mentions that Hunters often hunt Pseudoroids as a form of training.
