[Superman/Trek] An alien ship suddenly appears in orbit and crashes on a Kansas farm, ran by a kindly couple. Starfleet arrives, and discovers it has technology of utterly unknown and alien design, carrying what appears to be, at a glance, a human infant with black hair, swaddled in a red cloth...

The first Starfleet officer on the scene, pulling open his tricorder, immediately realizes the infant is anything but human, has presently unknown species DNA, and appears to be faintly catalyzing infrared, visible, and ultraviolet light into an unknown energy within its cellular structure. Within moments, the couple arrives, along with a huge Starfleet rescue and response team.

Pick a year between 2122 and 2375 for the crash landing.

What does the arrival of this strange visitor from another planet do to Earth, the Federation, and the Milky Way?

Actually pretty good things.

Humans will be fine with Kal-El: aliens are common place. What they can do that the kents can't, however, is match the Kryptonians in tech. They study the Pod, decipher its messages and learn his origins. They confirm krypton is gone, and the Kal-El will get powers.

If this was a darker galaxy, things may go badly. But Starfleet and the Federation are benevolent and utopian enough they're unlikely to conscript him into war. They raise him, and like his canon counterpart, he becomes a hero.

With Superman, one of the kindest beings in fiction, leading the Federation, one of the kindest orginisations in fiction? Things change. The Borg, the Klingons, the Romulons- their power is shattered. Superman is powerful and proportionate. Things will go well.

The Galaxy enters a new light age, under the gaze of the federation and its new shining hero.
