I now have over 250 million XP!

As of writing, I also have 491 in a shiny species living dex. I have more than 50 additional unique forms shiny as well, not counting Costumes, Shadow, Purified etc.

My missing 3* Counts are:

Kanto: 3 forms (galarian birds). I hyper trained my Mew so it was finally at least 3*

Johto: 9 forms (Unown forms)

Hoenn: 5 forms including 1 Species (Kecleon)

Sinnoh: 28 forms including 4 species

Unova: 3 forms (both Keldeo and the unimplemented Meloetta-P)

Kalos: 18 forms (including Hawlucha and all Zygarde formes)

Alola: 28 forms (including 11 species)

Galar&Hisui: 107+ forms (including 36 species)

Paldea: 81+ forms (incuding 70 species)

I have over 900 species in the game now.
