Ultraseven

Ultraseven (ウルトラセブン Urutorasebun), sometimes spelled Ultra Seven, Ultra-7 or just Seven (when being referred to by the other Ultras, including his son), is the third Ultra-being to come to Planet Earth (first and only in the spin-offs). He came to the planet after being sent to map the Milky Way, but this planet caught his attention and arrived here, he took the appearance of a brave man and renamed himself as Dan Moroboshi. Ultraseven protected Earth for a long time, but in the end, his power was weakening due to the numerous battles he had, he left Earth after his last battle without being able to say good-bye to his team members of the Ultra Garrison. However, at later times he returned to Earth to assist his other brothers-in-arms in catastrophic events, fighting against mighty aliens like Alien Hipporito, Alien Temperor, Yapool and Grozam. He later was revealed to have a son named Ultraman Zero, who became one of the most skilled Ultras from the Land of Light.
