Oisin Brennan

Oisín Brennan is a character in Fair City. He is a son of property tycoon Paul Brennan.

Oisín regularly engages in scheming, extortion and stalking. He is a fan of anonymous cyber bullying and attempted to use his father's wealth to keep the anonymous online opinion board Ask.FM from being liquidated.

An attempt was made on Oisin's life in September of 2019, but the gunman, suspected to be Dean Dowling acting on behalf of the Carrigstown Agenda botched the shooting and missed entirely. This led to Oisin creating a 4Chan post in which he announced that he would be setting up an opposition movement in retaliation against the agenda. This movement he named The Proud Boys of Carrigstown.
