The Pokémon in digital artist Michelle Zhu's paintings are so cool and relaxed, that I would just leave them to themselves and wouldn't try to catch them at all. This one above is a special mixture of Pikachu and Koffing, and he's having a great time.
Note: Mildly to moderately NSFW artwork follows.
Here's more; Swinubs with the perfect camouflage:
Sudowoodos, and stressful decisions.
An Onix, a Vileplume and a Seaking, drawn in a different, but still cool style.
And this Chansey is just... interesting.
