Cool! It's neat how you provided information about these Fake-subspecies.
The first thing i saw was "ancient alatreon" And i thought "Isnt that Dire Mir- Oh, these are fake subspecies of monsters!" And then i saw permafrost Dire Miralis.

The Ancient Alatrean kinda looks like Yveltal, and the Lead Uragaan looks kinda like Slobber Tooth!

Thank you!

ancient alatreon: nopenopenopenope
diamod/platinum raths: very cool
white peco: now the little rascal has an elemental trio xD
infernal agnak: bring it on
frost miralis: brace yourselves, winter is coming
blackbeard deus: don't battle me, you're not hardcore! [ERPH reference xD]

Zinogre FTW!
But anyways, very interesting subs c:
