Anderson ‘The Spider’ Silva is widely considered to be one of the pound for pound greats in UFC history, and rightly so. Thirteen times he has stepped into the octagon and he is yet to walk back out in defeat. He has also ended five of those bouts by way of knockout, earning him a spot on this list.

Silva, already a well established fighter before his octagon debut against heavy hitting, hard headed Chris Leben. If there were still some people who didn’t know who he was however they were certainly about to find out as It took just 49 seconds for Silva to become the first man to K.O. ‘The Crippler’.

Clearly ready for the big show, Silva next faced 185lb champion Rich Franklin who was looking to defend his belt for the third time. It quickly became apparent that Silva was more than a match for Franklin who quickly became entangled in ‘The Spider’s’ Muay Thai clinch and was powerless to prevent a barrage of knees landing before a final one fractured his nose, sending the battered and bruised fighter crashing to the canvas. It had taken Silva 2 minutes and 59 seconds to give another warrior the first K.O. of his career.

After terrorizing the middleweight division for several more fights the champion was looking for a new challenge, and found one with a step up to light heavyweight to face James Irvin. Would the debut at a new weight class prove to much for Silva to handle? It certainly didn’t appear to. With only 1 minute and 1 second of the first round gone Irvin was already lying out cold at the feet of the triumphant Silva.

He would go on to prove that was no fluke when he took another fight at 205lbs with Forrest Griffin at UFC 101 in 2009 and finished him in 3.23mins.  The final KO on his UFC resume to date occurred at UFC 126 in February of 2011 against Vitor Belfort, and was arguably his most impressive to date as snapped out a front kick that connected with his fellow Brazilian’s chin to provide yet another first round KO finish, the first clean knockout loss of Belfort’s 14 year career.
