With each generation we get some new dual type combinations that we previously haven't had before. Here are the unused type combinations as of Generation: What type combinations do you want to see in Sun & Moon? I would love to see some stronger poison types, so any new type combinations with poison would be great. Poison/Fire and Poison/Steel sound like fun. Fairy is still the newest kid on the block, and more combinations would definitely be fun. I would love to see Fairy/Ghost and Fairy/Dark.
