"Pikachu! He is flying type, you should do double damage to it!" Tama shouted pointing to the incoming Zubat. Pikachu nodded it's head and looked straight at the pokemon, if he could defeat this, it would be a perfect hit at improving skills. So without a doubt Pikachu first would start with a lightning attack, but before that, something else would need to be done.
Using the skill Quick Attack Pikachu attacked with a flash which would be invisible attack to Zubat. Later taking tail back, Pikachu did a quick Tail Whip at Zubat when jumping in air to hit him. This would make Zubat's defense weaker by one stage giving ability for Pikachu to do a trump card attack.
After the Tail Whip, Zubat rushed back at Pikachu with Wing attack. Pikachu was hit, but it dealt only half damage due to Pikachu's resistance against flying attacks. And with perfect opening, Pikachu had the time to attack. He jumped forward with quick attack to do a fast attack invisible for Zubat and finally with large amount of lightning gathering around body, Pikachu shot it all at Zubat with use of ThunderShock. The strike was deadly to Zubat, very deadly. It did double damage because of Zubat's weakness to lightning and extra attack because his defense was lowered by one stage.
Zubat at last moment tried to avoid but was hit by the ThunderShock falling on ground appearing to be knocked out. With confidence that Zubat is defeated, Pikachu turned around giving a smile to Tama. "Good job, that attack sure was deadly and must of been more deadly that it looked!" Tama showed a thumbs up for Pikachu. But he suddenly saw something. Zubat wasn't knocked out! He only acted like that, at opening it flied at behind of Pikachu attempting to bite it and then restore life. But thanks to Tama's reaction he shouted: "Pikachu, Look out!" and with use of Quick attack, Pikachu did a jump back and returned Zubat with a strong ThunderShock to finally knock it out with second super deadly attack.
This time, Zubat was knocked out for sure. "Ha ha, that thing almost got us, Pikachu!" Tama ran closer to Pikachu smiling. "You we're amazing!"
