The first appearing Alien Groza, Grozam is the third member of the Dark Four Heavenly Kings to fight Ultraman Mebius. Unlike his fellow teammates who prefers psychological manipulation and trickery, Grozam resorts to brute strength and prefers face-to-face combat against the Earth's protector Ultraman Mebius. Managed to defeat the young warrior and froze him to a nearby dam, he gloated his victory over the citizens but was reminded by Mefilas not to underestimate both the Ultraman and the humanity. When Crew GUYS revived Mebius, Grozam fought the young warrior and Ultraseven and once more proven his immortality after being shattered to pieces by their attack but his underestimation for humanity bites him back when Konomi of Crew GUYS used the Maxwell Tornado and burned his pieces.

A human sized Alien Groza reappears in this series as an AIB agent. He, along with his colleagues watched the activities of Kei Fukuide from the AIB base. When Kei discovered them observing him, he destroyed the field agent's disguising device and compromised the mission, leading to the control panel where the alien stood to malfunction.
Powers and Weapons
- Hell Frozen Breath (ヘルフローズンブレス Heru Furōzun Buresu?): Grozam can emit a cloud of quick-freezing mist from his mouth. This ice mist can be used to freeze entire lakes in just seconds and can even turn weaker energy attacks into ice, making them fall to the ground and shatter. He also claimed that he is capable of freezing the entire planet Earth within a matter of seconds.
- Ice Blast: Grozam can launch numerous, explosive blasts of solid ice from his mouth.
- Reformation: Having a body made completely of ice, Grozam is capable of quickly reforming should his body be blown to bits. This also means he has an enhanced form of regeneration, able to use his icy body to fill in large wounds and even keep him from falling apart when sliced in half.
- Ice Blade: On each of Grozam’s arms rest a long, deadly blade. These blades can also extend to sword-like lengths. Not only can he use these with great skill, but once stabbed into a victim, the blade can be broken and the victim will be frozen in ice, possibly forever.
- Freeze Pulse: Should Grozam be set on fire, he can release a quick blast of freezing air from his body, quickly dousing the flames.
- Size Change: Grozam can change his size from that of a man to that of a giant and back again. When at a human size, he will lose the spikes and blades on his body.
- Teleportation: Grozam can teleport anywhere he wishes.
