Lucario and Garchomp when facing them for the first time on Pokemon Black. (I hadn't played since Gen 2) I thought Lucario was a Dragon/Fighting type since it used Dragon Pulse on my Reshiram, and thought Garchomp was a pterodactyl Pokemon that was part Rock. Also, Garchomp ended up destroying my team.
