What is holding these Pokémon from participating in Poké Transporter?

Question

Hello everyone,

I have some issues while using Poke' Trasporter. I can't use poke' transporter with the following Pokemon that I have in a Pokemon Black 2 cartridge to Pokemon Sun (I don't know how the previous owner obtained this Pokemon):

Arceus lv.100
Captured with a pokeball and it had Pokerus (might be not legit? It is hard to belive that you can capture Arceus with a normal pokeball), got Gift Ribbon01 Premier Ribbon Special holiday Ribbon. Serious nature, ability Multytype.

Moveset:
Judgement 16/16
Extremespeed 8/8
Flash 20/20
Perish song 8/8

Mewtwo lv.100
Captured with a pokeball and it had Pokerus (might be not legit? It is hard to believe that you can capture Mewtwo with a normal pokeball), got Gift Ribbon01 Premier Ribbon Special holiday Ribbon. Mild nature, ability Pressure.

Moveset:
Psystrike 16/16
Aura Sphere 32/32
Me first 32/32
Future Sight 16/16

Groudon Lv. 100
Captured with Masterball, got Gift Ribbon01 Premier Ribbon Special holiday Ribbon. Brave nature, ability Drought.

Moveset:
Eathrquake 10/10
SolarBeam 10/10
Stone edge 5/5
Fireblast 5/5

Darkrai Lv. 100
Shiny, captured with Masterball, got Gift Ribbon01 Premier Ribbon Special holiday Ribbon. Serious nature, ability Bad dreams.

Moveset:
Dark pulse 10/10
Dream Eater 15/15
Dark void 10/10
Nightmare 15/15

In my opinion there is something wrong with Arceus and Mewtwo, but Groudon and Darkrai seem legit...

Do you might know with I can't transfer them with Poke Transporter?

Thank you so much for your help

I think Arceus and Mewtwo are hacked，and maybe Groudon and Darkrai have a special ribbon not allowing you to put them in Poke transporter.

If you're not sure, then you shouldn't post this as an answer.

Answer 1

Im almost positive the Darkrai is hacked. Level 100 shiny Pokémon that you randomly get from who knows where are dead giveaways of being hacked for one reason or another 95% of the time. I’m not sure about the other three though.

Answer 2

They all have ribbons that they cannot legitimately obtain/don't exist in the Pokemon bank files, therefore not allowing you to transfer them. I know this is super late after the question was posted but I'm just going around the site answering questions that don't have the correct answers to them.

Arceus can learn perish song, but the other parts of the answer are probably correct. https://bulbapedia.bulbagarden.net/wiki/Perish_Song_(move)

except the answer you posted on my question was not correct either...
