So, need some extra info to help you raise your team of extreme pokemon? No problem. Here is where I go more in-depth with the pokemon's strengths and weaknesses to help you deal with just how to raise them. Since many of the pokemon do NOT learn TM or HM moves, I won't list them. I will, however, list their level-up moves, and their basic statistics. If you want locations, look in the Team Extreme page.
