This is Togekiss, one of my favorite Pokemon of all time. Mainly because I pretty much solo'd Black & White 1 & 2 using one that Nintendo sent me as a birthday present. Given the right moveset, nature, and EV training, this thing can keep any enemy stun-locked with ease and sweep whole teams. On top of being fast and hitting like a truck, it is also just as bulky! Good luck taking it out without rock or steel moves.
