Yoshi needs an entire TEAM: He has a Blaziken for his fiery side, a Wigglytuff for his willingness to help others, a Skiddo for his inner child, a Goodra for his playful attitude, a Garchomp for his rather good athletic shape, a Noibat for his love of children, an Abomasnow for his icy side, and a Tyrunt for his wise-beyond-his-years IQ.
The Runaway Guys:
Chuggaaconroy: Donphan (OMG AS SOON AS I CUT OFF THE VIDEO I FOUND A PHANPY!!)
NCS: Darmanitan (You know IN THE BATHROOM.)
ProtonJon: Cacturne (Move. Faster. POKEY!)
JoshJepson: Azumarill (I have no idea why, but it just came to me.)
Lucahjin: Rapidash (She has an uncanny love for anything equine.)
MasaeAnela: Espeon (Her DeviantArt icon is one!)
Link:
Aegislash (Master sword/Hylian Shield)
Rapidash (Epona)
Celebi (Navi/Hero of Time)
Noctowl (Kaebora Gaebora)
Gallade (it just looks like him)
Electrode (bombs)
Also, I think that Exploud would be a btter fit for Emile (with how loud he is)
and Eggescute would be better for Jon (with his fascination for Wesker and his Golden eggs)

Starfy and Starly would have each a Latias and a Latios, respectively. Moe could have a Seel. Bunston feels right at home with several rabbit Pokemon, like Bunnelby and Azumarill. The Squirts would have a fully evolved starter team from each generation, with Bawss taking 6th. Old Men Lobber and Vern would each have an Aerodactyl and a Kabutops, respectively. Shurikit gets the Greninja, while Kittana gets the Samurott. The Terrible Trio each has a Kanto Starter and a Wormadam.
Ronk - Venusaur and Ground Type Wormadam
