So fun fact, if I could, I'd start with an Abra so that I could have an Alakazam quickly. One of my favorite pokemon though I love most Ghost, Dark, and Psychic types (from back in Ruby and Sapphire). So yes, if Walter was in the Pokemon world, he'd have a Alakazam.

The adorable art you see here was an amazing freebie from Keirajo =D She spoils me, really, because that Alakazam is perfect, and Walter looks sooo adorable it's painful oh my goodness~
