Arados

One day, the Team EYES discover a strange time stop. Upon their investigation, it was coming from Arados, a snail-like monster whom can stops time surrounds. After an analysis made by Doigaki, he reveals that the monster comes from Earth, but 5000 years from the monster. It had been travelling through time due to it's evolution period but the monster is still a cub and due to this, it had a weak immune system where it can't adapt itself in the modern era. Later, Alien Nowar communicates at the EYES Base where he demands Arados and in return, they can heal the monster and Earth will no longer under their target. After a talk with JADF Army, they decided to object Alien Nowar's offer and give it to the army if the monster dies for autopsy which might be beneficial to humanity, something which Musashi disagrees. Getting impatient, the aliens kidnapped Arados via their spaceship. Luckily, they managed to free Arados but the Alien Nowar lanched Ragstone-Mechalator to duel team EYES. Cosmos appeared and battle the cyborg monster but quickly overpowered by the two monster and alien teamwork. Arados uses his last power to banish Ragstone-Mechalator into another space time and finally died due to exhaustion. Cosmos furiously destroy the Alien Nowar spaceship and flies away. While Musashi and Captain Hiura honouring the died Arados, suddenly a portal emerge where three adult Arados appear and use the time reversal ability to revive Arados.
