Pikachu never really liked Spearow.
They were nasty little buggers, always picking fights with others and bullying pokemon that were weaker or afraid of them. Even when he was in the wild not to long ago had these birds been a problem. He shuddered from where he lay in a crumpled heap on the ground, his cuts stinging from where the Spearow jabbed at him. Thunder crashed, drowning out the dull patter of rain and Ash's screaming. He couldn't find the strength to move.
Yes...Ash. The boy he had disliked the moment he was released from his pokeball. Pikachu was still pretty bitter about being shoved into one after being captured from the wild. He wasn't happy about being dragged around by a clothesline either from this boy. It seemed the two had gotten off to a rocky start.
But the more Pikachu stared at the boy in front of him, his arms spread out wide as he shielded and protected him from the frightening Spearows, the more he re-thought about this boy. He remembered how kind Ash had been to him even when Pikachu wanted nothing more than to do his own thing. How Ash picked him up and hugged him when he first saw him, a joyful smile on his face. He then remembered how Ash had carried him when the Spearow began attacking. His mind flashed to a few minutes ago, where Ash tearfully placed his pokeball infront of his fallen Pikachu, begging him to return inside and save himself. And all Pikachu had ever done for him so far was give him a good shock.
This human- No... His friend really cared about him...and Pikachu felt a swell of emotion in his tiny heart. He realized he cared about him too. He felt ashamed of himself for being so mean to his new trainer.
Lightning flashed, splitting the sky. Pikachu felt the electricity escape his cheeks, hungrily seeking out the lightning bolt as he drew strength from within himself.
Ash was still screaming at the Spearow who hovered dangerously in the sky, screeching right back at him. A flash of lightning and a boom of thunder later, the Spearow dived at him, sharp pointed beaks ready to strike.
With all the remaining strength he had, Pikachu hauled himself off the ground and tore towards his endangered friend. Time seemed to slow down as he easily climbed up Ash's pant leg, onto his shoulder, and with a leap of strength, into the air. He was face to face now with the rapidly approaching Spearow, their dive continuing on. The crackling lightning from the storm set his fur on end, static coursing through his veins as electricity snaked from his bright red cheeks, charging up power as he released a crackling explosion of electricity.
"PIIIKKKAAAACHUUUUUU!"
And everything went black.
Suddenly sunlight pierced through his eyelids, and slowly he opened his round brown eyes. The storm had stopped, and a beautiful rainbow arched overhead. He looked straight across him, into the eyes of his trainer who had just woken up too. The locked gazes, smiling and nodding to eachother. They didn't need words to understand what they were telling eachother. They knew from now on that they would stick by eachothers side no matter what, and it was at that moment that a Pikachu and a Boy named Ash became best friends for life.
As time went on, Pikachu grew to appreciate those fiesty little birds. For they were the ones that really brought Ash and Pikachu to understand and care about eachother. And what ever dangers they faced, Spearows or not, they knew they would face them together.
