Since I have a wild imagination, I like having my characters (pokemon or any others) comment or talk in general. Since most of my friends range from Sonic to Mario to Pokemon to and others, I decided to name all the characters/creatures that talk (Some don't have names)

Pokemon
Roy; male Lucario
Richie; male Lugia
Ratio; Latios
Rati; Latias
Dialga [no nickname]
Aaron; male Infernape
Otto; male Golduck
Max; male Politoed
Blaze; female Blaziken
Stephanie; female Sceptile
Louie; male Psyduck [P.E.]
Violet; female Pikachu
Maria; female Poliwhirl [green]
Beauty; female Gardevoir
Lance; male Kyogre
Rose; female Lugia [shiny pink]
Amber; female Torchic [P.E.]
Zack; male Treeko [P.E.]
James; male Mudkip [P.E.]
[Any others, will be added when new stories or event happen]

Dragon
Aiedail; male green dragon
Angel; female white/lunar dragon
[Dragons either speak normally or in italics if speaking through the mind]

Made clear that they respond on their own time. I respond with my original name (Mark), if I'm there. As for any other characters, if I can find them, I'll add them (Sonic or Mario characters).

EDIT
Like I said before, when I could get the others to join, I meant it. But I didn't expect them to come to me... was quite a surprise..

Others
Vince; a mix breed of a hedgehog and pokemon...mostly hedgehog, but can use any pokemon attack at will
Shade; my fan-based version of Shadow the Hedgehog
Mystic Shy Guy; based off the voice from the flash Bowser's Kingdom on Newgrounds, this shy guy is a one of a kind comedy block.
Shadic; a hybrid hedgehog created with the machine of Tails and Animatic's Tails; a cross-breed of sonic, shadow, and silver.
Cyreo & Anthony...[no explanation yet]
