If this was an omegaverse his brother would be a recessive power bottom omega who was neglected by his runaway mother and abused by his dominant alpha father who is obsessed with his children being dominant alphas. He went through school pretending to be an alpha and
in turn learned how to fight. So he goes around beating up alphas who thought about taking advantage of Omegas. He likes to talk a big game and put out an egotistical front but in reality he would be naive & severely wounded on the inside. & Most likely would go into a spontaneous heat in front of his dad arch enemy super dominant son. Who coincidentally secretly like him since kids but instead of telling the brother the arch enemy son bullies, antagonize, flirts, and occasionally ask to sleep with him in a joking but not really joking matter creating a love/hate relationship. Where the arch enemy likes to refers to them as friends the brother sees him as an annoying sexy fucker who he can't get rid of.
