*From start of career.
(Boxrec.com)

Edwin Valero (pictured) is the only fighter to have had an 100% knockout record and held a world title. 27 knockouts out of 27 fights including 19 in the first round would indicate impressive punching power. Valero was not a one punch knockout artist but instead overwhelmed his opponents with clusters of solid blows. This is highlighted by the fact that 21 of his stoppages were TKO's as opposed to clean knockouts. (Ed. writes - there is an anomaly with 'TKO' wins though. For example, if a boxer is basically knocked out before he hits the deck and the referee rightly dispenses with the count - as in this fight - it is classed as a TKO rather than a KO. This is something which should be addressed in record keeping.)


pasted straight from boxrec- but seems relivant to thread

Missed out Tyrone Brunson. He was cr@p, but still beat Valero's record for 1st round stoppages, by beating stiffs and old women. Or something like that.
