Capt. America vs Batman

Its all about the shield. I think captain america would win because all those who chose to oppose his shield must yield. Seriously though, Pikachu would fry them both.

I see it now.... as Pikachu launches into the air, lighting up the arena his battle cry PIIIIIIIKKKKKKKKAAAAA is silenced with a thud.

Picture a pikachu impaled onto the Cap by a Batarang.

with little soft mewling pika noises ...pik.. pik..cough...pikkkk...karrgh.

The Cap would rip out the Batarang from his chest, wiping the blood stains off his star with the lifeless form of Pikachu before dropping him to the ground without a second thought.

or perhaps he would step on him as he get's back into the real fight.
