The 31 year-old has lost 42 pounds in weight since his last fight, a loss at heavyweight against world-rated Alexander Povetkin, and was due to fight Tommy McCarthy until the latter pulled out.
In stepped undefeated Slovakian Viktor Biscak at just a few days notice and with a record of 10-0 to his credit.
As Perez aimed to shake off the ring rust, the Irish-based Cuban had clearly intimidated his opponent pre-fight with his new exceptional physique.
It was apparent from the off the Biscak wanted no part of Perez, and with only a debatable couple of blows landing, the fight was over.
Eddie Hearn must have been slightly disappointed the bout ended so soon, with Perez stating after his maiden 200 pound victory that he wants to be kept busy in 2017.
Without any evidence to back it up, it’s hard to comment on how good Perez looked, apart from his obvious physical attributes.
Also on the Belfast bill, James Tennyson halted Ryan Doyle in six rounds, whilst Paul Hyland Jnr wasted no time getting Adam Dingsdale out of there in the first.
There were also victories for Luke Watkins, Paddy Gallagher, Feargal McCrory and Tyrone McCullagh.
