Okay so they are variations on the legendaries because why not and this got really long really quick. ;v;
First up is the Solar Mew!
They pretty much exist solely in outer space and spend their entire lifespans drifting about from star system to star system. It’s unknown if they originated from Earth and migrated out into universe where they developed into a distinct subspecies or if Earth mews are a settled population of solar mews. Nobody really knows.
Their existence was first brought to attention by high-res deepspace photographs in which small but incredibly luminescent mobile anomalies were detected. More dedicated photo searches showed that the anomalies were actually spacefaring mews!
These mews are constantly surrounded by a nimbus of their psychic power which is thought to filter the ambient radiation and provide protection from the vacuum of space. The energy that they are constantly extruding actively distorts their physical forms and makes it appear as if they are casting off fragments of themselves unless certain viewing filters are applied.
As of the moment two solar mew individuals have been identified and are being tracked remotely.
– attempt at scientific jargon aside-
They are are variant of mew that is highly energy based to the point where their psychic abilities are starting to bleed over into other energy types. There’s a whole bunch of them out there in the universe and they keep in touch with small psychic pulses that fold space for near instant travel. It’s more of a ding on a radar than actual communication.
They tend to have certain star systems that they prefer to drift around with each ‘lap’ of their territories taking about a good millenium or so to complete. Every so often a migrating solar mew comes through and crosses paths with the established mew though interactions are always peaceful and end with the traveler being accompanied to the far reaches of the system as they go on their way.
Occasionally a solar mew will stray towards the earth but never really come inside the solar system or approach the planet itself.
It could be that with their constant contact with each other that they are waiting for some kind of signal….

Next is the Timewarp Celebi!
These guys tend to be bound to specific objects or locations. They never really come out of the fourth dimension and are more content to watch than ever really partake or interfere with the rest of the world. What catches their attention is pretty narrow in scope but that doesn’t mean much when one timewarp celebi can be completely dedicated to a single rock and follow it’s path from the individual atoms that formed it coming together to create it’s elemental components to it’s future as scattered grains of sand, with each grain being accounted for and monitored. There’s a time warp celebi for just about everything in existence which ultimately comes back down to infinite variations of a single entity. Consider them the secretaries and librarians of everything.
When they do pop out of the fourth dimension they age very rapidly before regressing just as quickly to their prime. This fluctuation in appearance can be rather unnerving to the unprepared. On their backs are not true wings but instead flower petals. Beyond this and their role in the grand scheme of things they are essentially regular celebis.

Starbound Jirachi is next.
Another variant that is almost exclusively space dwelling. Space is cool yo.
So these jirachi are born within star and cocooned by psychic wrappings to protect them from the immense heat and pressure. They are released when their star dies and end up getting rocketed out into the universe by the explosion.
They are built to be the perfect receiver for collective consciousness and are attracted to sapiently populated worlds. Once they get within range they attach themselves to an iteration of the planet and feed from it, turning the collective wish for that world into reality. More often than not it doesn’t end well for the world in question.
After feeding the starbound jirachi will find an appropriate star to hibernate in before the process begins all over again. For each cycle completed the starbound jirachi gains a star on its mantle, and upon getting three can compress them into a jirachi seed to plant the core of a suitable star to give birth to a new starbound jirachi.
