Screamer

Screamer is a Kaiju that makes peoples heads explode with his screams.

History
He first appeared in 1975 in Universe 65 where he fell from space into Tokyo frozen. But he soon woke up and started destroying Tokyo's buildings with his screams, while making peoples heads explode with his screams. Everything was exploding. Even Titanium, while he walked around the city. But he started being attacked by Derpy people who climbed onto him. He let out the most ear-piercing screech ever which made their heads explode. He was approached by Re-Detton. The two kaiju got into a fight destroying a major part of Tokyo. Screamer had the upper hand with his screams weakening Re-Detton. Soon Ultraman Jack appeared and the two kaiju joined forces to fight him and almost killed him. Jack was saved my Greenman. The fight lasted long and was evenly matched. But Re-Detton was soon killed by Jack and Greenman who shot their beam weapons at him which killed him. The same happened to Screamer.

Fighting Segata Sanshiro
He once again attacked Tokyo after being revived somehow. Segata Sanshiro after re-entering Earth's orbit fell on top of Screamer and the two fought. Segata summoned a clone army and grew to giant size to fight Screamer. In the end, he got thrown into the Nintendo HQ which made him explode.

Roar
His roar is literally Michael P's screams.
