YOUTUBE star Ryan Taylor was left with a gruesomely swollen eye – which left him beaten against Swarmz.
Swarmz was out for redemption after he took a fight against KSI on two weeks notice in August.
The rapper, 26, was mocked for his unorthodox and inexperienced style but vowed to prove the doubters wrong.
And he did so in controversial style as a jab in the first round left Taylor, 29, with swelling so bad the referee deemed him unable to continue.
Per the rules, as the shot was a punch and not an accidental blow – such as a headbutt or elbow – Swarmz was declared the winner.
He said: “It was a jab, a touch, we’ll call it a little touch.
“But you know what? I’ve been working hard for this, everyone saw me get battered against KSI, making fun of me calling me a ballerina.
“It’s been playing on my mind and I had to get redemption.”
Swarmz, 26, called out Deji, 26, the brother to KSI, 29, who was sitting ringside, as well as YouTuber King Kenny.
He said: “Next fight I’m ready. Where’s Deji? Where’s Kenny?”

Swarmz added: “All the respect. I worked hard, Kenny and Deji, very good. they’re top of the game, good fighters.
“That’s what I’m trying to do, to prove myself. I do respect them. I can’t wait for it to happen.”
Swarmz now moves to 1-1 as a crossover boxer following his win on KSI’s undercard.
