Ultraman Ace
Yapool targeted Kenta's pregnant mother, Yoshiko and pretended himself to be Kenta's faraway father to mail him a red gemstone as a gift (with a bit of Yapool's curse). Yapool (in disguise of an old man) manifest Mazaron Man out of his hatred towards Ace and summoned a red rain via the red gemstone in the said boy's possession, causing his mother to slowly transform into Yojo. As Kenta chased her, Yojo went inside the Mt. Fuji, Mazaron Man's hideout and performed a ritual to gave birth to Mazarius. Mazarius was later born and began to terrorize. While Ace fought an enlarged Mazaron Man, Kenta used the gemstone he brought along. Remembering it as a source to all of this problem, he threw it to his mother, turning Yojo back into Yoshiko and thus, deleting Mazarius out of existence.
