Okay, to celebrate this thread being back, time for me to post more worthless shit.
The Pokemon Bank update finally has us being able to transfer not only Gen VI Pokemon to Gen VII, but Pokemon from the Gen I Virtual Console releases.
Though there is some compatibility issues, which I will note here:
-Pokemon that know a move they cannot learn via Level up or TM/HM cannot pass(So moves obtained via glitch and Stadium/Event moves for those to successfully transferred their cart save to the VC version, which is possible but both expensive and time consuming)
-Pay Day Mewtwo can not pass, either, even though it can learn the TM in Red/Green/Blue(But not Yellow)
-All Mew Glitch Pokemon except Mew itself can pass through just fine. Only the Mew from the Real-life event in Japan and Britain is transferable without using glitches.
-If MissingNo. is in your transferred box, it does not transfer but it shifts the name of all the Pokemon in the box down one (Like the weedle below MissingoNo. is now named MISSINGNO-, and the grimer after that is named WEEDLE)
-Mr. Mime that aren't nicknamed(aka only via the Mew glitch) are named MR- MIME when transferred
-Characters that exist in Gen I but not Gen VII, like the [pk] and [mn] symbols, are converted to the nearest thing to them in the new games (In the case of these two, P and M, repsectively)
Now for the details on the Transferred Pokemon
-Their nature is based on what their current EXP divided by 25 is.
-Gender is random
-Shininess is possible, via the having same DVs that created Shinies in Gen II but Attack and Defense are(most likely by accident) swapped
-They always have their Hidden Ability unless that species doesn't have one(so no No Guard Fissure Machamp
-All Pokemon have at least 3 Perfect IVs, except the event Mew who has at least 5
-EVs are 0 on all stats
-They have a marker that looks like a little Game Boy, similar to the Gen VI Pentagon and Gen VII Clover
Also of note is that digging through the coding of bank, we now know that there are 7 Games tied to the Gameboy marker, which means that Gen II may eventually come (since in Japan there are 4 Gen I games and 3 Gen II games), additionally there is data for Pokemon transferred from Go at some point in the future, where they also have a unique marker, a G with a circle around it.
