In terms of slapstick violence, I have to go with the original Indigo series. It includes Misty knocking a Caterpie high in the air with a hammer (Ash catches a Pokemon) as well as roundhouse kicking Brock in the face (Charmander the Stray Pokemon), Brock punching Misty on the top of the head multiple times (Bulbasaur and the Hidden Village), Team Rocket getting pelted with Pokeballs (School of Hard Knocks), Mankey/Primeape beating the crap out of Ash and Brock and causing Jessie to faceplant into a boulder (Primeape goes Bananas), Ash getting pinned to the wall with ninja stars (A Ninja Poke-Showdown), Ash getting drilled in the face with a boomerang and Misty popping a little boy in the face (The Kanghaskhan Kid), people getting lit on fire as well as Ash and Co. bouncing off of Team Rocket's heads with bikes and knocking them off a bridge (The Bridge Bike Gang), Misty knocking Ash to the ground (at the end of the Battling Eevee Brothers though she does this many other times to him), and of course, Team Rocket blasting off again, and again, and again, and again! I'm sure there are many other funny, violent scenes I am missing. Wow, never realized how much violence I was exposed to as a kid!
