We might experience hundreds of random encounters over the years in Pokemon games, but everyone seems to remember one specific kind of encounter: Zubat ones.
It always happens a little like this: You're deep in some cave somewhere. Your Pokemon are hurting bad; you need a Pokemon center. You're almost at the end of the cave though. Hooray!
And then your repels wear off. Suddenly, it's like a billion Zubats appear out of nowhere and attack you every step of the way out. It's incredibly annoying. But that's kind of what makes this Lucca Comics and Games cosplay posted by avlas of repels wearing off so silly: we've all been there. The Zubat on the face is a nice and necessary touch, too:
That's Italian. If it was in English, it'd say something like REPEL'S EFFECT WORE OFF.
Thankfully, for X & Y at least, Zubats seemed to be a smaller problem.
