I view Dan Moroboshi/ Ultraseven as the character that first appeared in the 1967 show. And the show to an extent too. So basically without viewing it as part of the ultra universe as it was originally intended by Tsuburaya.

So an alien who fell in love with earth and Mankind that sacrificed everything to save it and it’s inhabitants. Of all sequels to ultraseven, heisei ultraseven is easily the best continuation of the character and probably the only one that is truly in the spirit of the original show.

Because in heisei Ultraseven he even breaks the rules of the universe to protect mankind even through they are not even the natives inhabits of the planet. And by breaking that rule he does not only get exiled by his people, no he even gets imprisoned.
