Alistair Overeem knows a thing or two about making a huge impact in a UFC debut.
Nearly a decade ago, the former Strikeforce, K-1 and DREAM champion was making his first appearance inside the octagon for a showdown against ex-UFC champ Brock Lesnar at UFC 141.
At the time, Lesnar was already a proven pay-per-view superstar. But Overeem had the credentials to earn that fight for his debut, and he wasted no time proving why he was such a high-value free agent pickup. In a one-sided affair, he battered Lesnar with strikes before ending the fight with a brutal body kick to send the former heavyweight champion packing back to the WWE.
