Beznick all the way.

Back in 2009/2010 he was the most dominant player in the book of records scene.

-He was the 1st person to perform a 6 dismemberment boomhit
-1st person to achieve 1,000,000 points in one hit
-Crushed multiple other records by a large margin. These include Fastest Self Disqualification, where he cut the former record in half, Highest Dismemberment Threshold Decap, nearly doubling the dismemberment threshold of the previous record, and Most Points in One Hit, beating the previous record by 300,000 points.

He has since been inactive for years now and no longer holds any records (his final record that stood was Fastest Uke Disqualification. It stood for over 7 years and was snatched up by Jaker earlier this year), but his legacy of being an absolute monster rampaging through the Book of Records, very high skill back in 2009, and made records look very impressive and appealing to the eye will never be forgotten. He was pretty much Jaker before Jaker even knew about the BoR
