Skyla throws a rock at Charizard, who faints on the spot like the terrible Pokemon he is.
We don't know what levels the battlers have. We don't know if Skyla can learn Rock Throw. We don't know if Skyla can outspeed Charizard or OHKO it with Rock Throw because we don't know her base stats. We don't know if Charizard is holding a Focus Sash or a Charti Berry. We don't know what Skyla is holding. We don't know if Skyla's ability makes a difference. Etc.
Why do I have to move with the crowd of kids that hardly notice I'm around? I work myself to death just to fit in.
