Eubank was dropped and stopped for the first time in January by Liam Smith – leaving his career on the line in their rematch.
But the middleweight son of a legend returned the favour back in Manchester with a round ten finish.
Conor Benn and Kell Brook – both names heavily linked with Eubank – were sat ringside as guests.
And Eubank, 33, warned: “There’s some big names out there. I see a few of these guys in the crowd, I’m coming for you!
“I’m coming for you Conor, I’m coming for you. I’m coming for you Kell, I’m coming for you.
“Anybody else who wants it, we’re going to put on a show for the fans, that’s for sure.”
Brook, 37, retired after beating Amir Khan, 36, in their grudge match last year but he has since teased a comeback.
And Benn, 26, was meant to face Eubank in a 157lb catchweight clash almost 30 years after their fathers’ famous rematch.
But the unbeaten welterweight failed two drug tests and has been fighting to clear his name since.

Last month, following a video-call hearing with the National Anti-Doping Panel, a provisional suspension on Benn was lifted, freeing him to fight again.
So promoter Eddie Hearn has already lined up the pair of boxing prodigies to renew their family rivalry.
But Eubank also called out middleweight icon Gennady Golovkin, 41, who he was due to fight all the way back in 2016.
He said: “Listen, I want to fight Triple G.
“I don’t know where he is right now but wherever you are Gennady, you’ve been holding onto them belts for too long.
“I want to take one so let’s get that on if we can, 100 per cent.”
Golovkin did hold the WBA and IBF title until he vacated both in March.
