Ultraman Dyna

An alien that made his way to Earth, Alien Chern first made his presence known, attacking Shin Asuka in his human form and throwing him. The alien decided after a short hand to hand fight to show his true self and Asuka shot him several times, but the energy blasts went straight through him, leaving him unharmed. After more physical fighting, he kicked Asuka over several oil barrels but as he rushed to find the human to continue the fight, Asuka got the drop on him, pointing his gun at him. Alien Chern was quick to remind Asuka shooting him didn’t work, but Asuka wasn’t aiming for him, instead aiming at the barrels, engulfing the Chern in a huge explosion and seemingly killing him but Asuka wasn’t sure whether or not he’d killed the mysterious alien. But Chern wasn’t dead yet, despite being badly burned all over his entire body by the explosion. He met with the creator of a popular monster fighting game, Monster Coliseum, the point of which was to create and battle with a created monster, which you could evolve through battle. They’d discovered an ideal test subject for their plan, a boy who’d made a monster called Demagorg, sending him an upgraded disk to see how his monster would fair against Ultraman Dyna and the monster was perfect for their needs. Chern and his partner called Asuka into the office, knowing his true self. However, the man turned out to be the first Chern’s superior, revealing this to Asuka and unleashed Demagorg on the real world. As Asuka prepared to transform, the alien grabbed his Reflasher from his hands. Watching the monster attack, Chern decided it was time to watch the fight, giving Asuka back his transformation item. After Demagorg’s control was destroyed, the first Chern reported the situation to his superior, explaining Demagorg was no longer under their control. The aliens didn’t notice until it was too late that Demagorg was approaching their building, only being able to scream out in terror as the monster smashed through the building, killing both aliens in the resulting explosion.
