Keep it a secret?

[Blaziquaza]

If it was something like Torchic, I'd probably just go to it, feed it every day or something.
If it was Zekrom or Rayquaza, I'd consider telling my friends. And just ride it everywhere, while up in the sky. :P

 

[RHCP]

Well first of all, I'd faint.
Then I'd go & tell my sister; no one else.

 

[Lunyka]

I'd tell my boyfriend but that would probably be about it. I wouldn't take them out of their habitat unless they wanted to go. Although it would be nice to have an Eevee and things, although it would be weird for it to lay eggs like a platypus.

I would go put arceus in a cage and make him eat my enemies

wowww... very team-rocket esque of you..

 

[mew_nani]

Well, first of all I would catch said Pidgey or whatever. Then I would make it my loyal partner, and fight crime with it. :)

Sadly Poke Balls don't really exist.... Ah well, a rope would work just fine. :)

Would I tell anyone? Probably not. If the wrong person found out, disaster and Pokemon cruelty would ensue. :( So I would keep it a secret at all costs.

P.S. if anybody finds a Riolu on planet Earth, let me know. :D

 

[Regeneration]

I'll record a video and post it on Youtube. >D And perhaps catch one with a net or whatever I've got.

 

[Echidna]

i would keep it a secret, and take one as my personal bodyguard if the need ever escalated to super 'needy' levels.

 

[mikey]

I'd keep it a secret so the government can't do experiments on them xD

Keep it a secret...watch them to see if they use moves, and...if they were something cool like Charmander...figure out a way to befriend/capture one :P

Sadly, if pokémon were somehow real, in this world it'd be a disaster, for reasons that I see explained in many threads (often titled "If pokémon were real...")
