Togekiss

Any Pokemon that wields a 60% chance to flinch is bound to be annoying, and Togekiss is no exception. With a meaty base 120 Special Attack, two solid abilities, and a wide offensive movepool, Togekiss is a very able offensive Pokemon, thanks in particular to Nasty Plot, one of the best boosting moves in the game. It's no slouch defensively either, with 85 / 95 / 115 defenses and a decent defensive typing giving it impressive mixed bulk. These factors are complemented by a great defensive movepool, with access to Wish, Roost, and Heal Bell.

However, a nasty weakness to the omnipresent Stealth Rock severely hampers its defensive potential. Weaknesses to common Ice- and Electric-type moves don't do it any favors either, especially because Togekiss is slower than most users of these moves. Nevertheless, incredible versatility, a phenomenal movepool, and balanced stats combine to make it one of the most threatening Pokemon in the UU tier.
