Edwards is on the comeback trial at a new weight after a 19-month break from boxing following a spell as WBC flyweight champion between 2018 and 2019.
The Londoner has just one loss on his record in 20 fights while 36-year-old Essomba has accumulated eight defeats in 21 bouts.
Sunny, who is also a former world champion at flyweight, says he intends to use his presence to get under his brother’s skin.
“The biggest reaction I’ve got to this fight is, ‘oh you’re choosing money over blood, and how are you doing that to your brother?’ But the funniest thing is, I have never taken a penny off Thomas,” Sunny said.
“Come fight night you’re going to see me very well dressed, smiling. Making it all about me to be honest. I think that’s how I’m going to get Charlie.”
While the presence of a family member in the opposite corner might be a distraction to some fighters, Charlie says he is “grateful” to his brother who helped make the fight with Essomba happen.
“Really he’s delivered me his fighter, the European title, on a platter when I was in the ‘who needs him’ club,” Edwards said.
“No one wanted to fight me, no one wanted to entertain me. They were just leaving me out on the sidelines because I am too good a fighter.
“So you know what, Sunny Edwards, I am so thankful, so grateful.
“The power is in my hand, I am going to go out there and do a number.
“On Friday night I am going to give you a big hug.”
