Pokemon: Upsets

[Pool]

With any and all fighting games comes the most likely to win and the most likely to lose. Tell me about a time when the most likely to lose actually won.

I was in the Battle subway earlier and these three happened:
Serperior beat Vanillish
Charizard beat Palpitoad
Charizard beat Frillish

They're all level 50 in the battle subway, so you can't argue that mine were a higher level.

Let me also point out that my serperior has only grass moves and beat the ICE type Vanillish xD
