Following surgery, Aspinall warned he was feeling "better than ever" and looked in the best shape of his UFC career as he weighed in at a muscular 258lb, compared to Tybura's 246.
And he backed up his words with one of the most impressive performances of his career.
His walkout was preceded by a quote from former sparring partner Tyson Fury, broadcast over the PA system, with the WBC heavyweight champion discussing coming back from adversity.
Just seconds into the fight, Aspinall tested his surgically repaired leg to devastating effect, launching a right high-kick with rocked Tybura.
That prompted a huge reaction from the fans as Aspinall's name rung throughout the arena.
The Pole recovered, but Aspinall's speed was already proving to be a big advantage as he moved in landing shots, before backing off to avoid return strikes.
The defining moment came swiftly as Aspinall landed an elbow and follow-up punches which sent Tybura down, before the referee stopped the fight on the ground.
The home fighter sprinted to the cage in delight, before climbing it and raising his arms in celebration as emotion poured out.
