Speaking of this topic, I couldn't help reminding the editors of the continuously evolving monsters in Contra. Contra's entire series is centered around "Uranus Ghost" and "Uranus Dragon Ghost" and Uranus Ghost's sister "Black Snake". During this period, they bred and split up a lot of strange creatures, and these monsters continued to evolve as they adapted to the earth's environment. Some bugs that seem relatively small in the early stage, continue to change shape with the increase of versions, and even become the ultimate BOSS in the later stage.
Like the infernal beast in Super Contra, it is already the final BOSS in the FC version, and the appearance can bring players a very shocking feeling. After customs clearance, we think this BOSS has been completely eliminated and will not appear again. However, in the "Contra 3" period, players discovered that the previously destroyed infernal beast had made a comeback, and only one of them had been destroyed before. Thousands of unshaped underworld animals were also bred in the nests deep underground, and at this time the underworld animals already possessed a certain evolutionary ability.
There are many evolutionary directions for the underworld animals, depending on the objects they devour. The first infernal beast possessed the face of a human female and devoured humans. In "True Contra" and "New Contra", the Yin Beast successfully evolved its tentacles, and at the same time possessed the ability to move quickly, then went to sleep underground. When the player encountered it again, they had evolved wings. Has the ability to fly continuously, but still retains some human appearance. The fear of reaching the heart is not how creepy the monsters look, but that these monsters have evolved human characteristics.
Until the "3D Contras" period, the ghost beast finally evolved and possessed butterfly-like wings and human wisdom. This is the most perfect form of the ghost beast and has the strongest destruction ability in history.
There are also a lot of monsters that can evolve in the alloy warhead series, but it is estimated that many players have not noticed it!
In the fourth stage of Metal Slug 3, players first came to the rebel's secret experimental base. A large number of horror creatures have been found here, among them cannibals and Martian tapeworms. The behind-the-scenes leader in cultivating these creatures is the modern disguise of Martians. Its purpose is to slowly erode the Earth by cultivating Martian creatures, and to make the Earth a living environment suitable for Mars. According to the official introduction, cannibals are the product of genetic mutations after rebels injected Mars virus into certain plants. What the rebels did not expect, however, was that the cannibals had an amazing speed of evolution and reproduction. Fortunately, they are not yet suitable for environments outside the laboratory.
In subsequent experiments, Cannibal took root and absorbed the water and soil resources near the experimental base, and the surrounding environment became lifeless. During this period, cannibals gradually evolved the ability to swallow and bite, and even directly swallowed humans. A large number of regular army prisoners became their ration. As cannibals adapt to the global environment, they can move more and more. After taking up enough nutrients, cannibals take root and evolve and spread seeds, but life has come to an end.
Researchers collect seeds and conduct secondary cultivation in order to cultivate cannibal flowers that can perfectly adapt to the global environment.
In the fourth level scene, players will find a large number of cannibal seeds are being spread to the world. Such seeds will grow as soon as they land, and quickly evolve into cannibals. If animals touch these seeds, their bodies are immediately absorbed into plants. Fortunately, at present, piranha seeds can only grow in the laboratory and nearby areas, and seeds that are spread to other places cannot reproduce.
