>>38610611Ditto would be fun. They're cute, and while you can't always have the right Pokemon for every situation on a journey, Ditto can become any Pokemon. Lost in a cave? Find a zubat for my ditto to copy and echolocate myself out. Need to get across a river? Find an aquatic Pokemon for ditto to copy and get me across. So long as I'm out in the wilderness, there should always be Pokemon around for my pal Ditto to emulate, and it'll force me to learn the strengths and weaknesses of many different kinds of Pokemon so I know how to instruct my Ditto successfully while it's transformed.
