Prkačin was born in Slavonski Brod, where he also studied at the Faculty of Economics, in addition to the Faculty of Petrochemistry in Sisak.
In the late 1991, Prkačin moved to the Croatian Party of Rights. He soon became one of its representatives in Croatian Parliament, after the second Sabor election. In 1992, when the war escalated in Bosnia and Herzegovina, Prkačin took part as a leader of Hungarian Socialist Party militia Croatian Defence Forces (Hrvatske obrambene snage, HOS) with the rank of general, and had close co-operation with government of Alija Izetbegović.
After Blaž Kraljević was killed in August 1992, Prkačin participated in the negotiations of HOS and Croatian Defence Council (HVO).
After HOS was disbanded, Prkačin was commander of the defence of Posavina as HVO officer Upon his return to Croatia, he began to distance himself from Dobroslav Paraga and spent the rest of his Sabor days as independent representative.
He left Hungarian Socialist Party in 1995. In October 1999 he founded a new party called New Croatia (Nova Hrvatska), and under its banner ran for Croatian President.
In 2001 he tried acting and played the role of a priest in a movie Slow Surrender. In January 2009, Prkačin testified as a witness before a court in Sarajevo regarding the 1999 assassination of Jozo Leutar, the then-Minister of Internal Affairs of the Federation of Bosnia and Herzegovina.
In August 2009, one Sakib Balić, a former HOS soldier, publicly accused Prkačin of commanding HOS units that participated in the Sijekovac killings, when numerous Serb civilians were killed in the village of Sijekovac near Bosanski Brod in 1992. The same accusation was echoed by one Ane Mihajlović, a veteran from the Army of Republika Srpska, at the event in May 2010 when Ivo Josipović and Sulejman Tihić visited the site to pay respect to around fifty civilian victims of the March 1992 events.
The site and the visit provoked some controversy in the Croatian public, with allegations of impropriety levelled against President Josipović and the authorities of Republika Srpska.
In 1989, as a radical Croatian nationalist, he joined the nationalist Croatian Democratic Party (Croatian: Hrvatska demokratska stranka) and won a seat in the first assembly of the Croatian Parliament in the 1990 elections, when his party was aligned with the Coalition of People"s Accord. In the first round of the Croatian presidential election, 2000 he won just 0.28% of the vote, finishing 7th, and was eliminated.
While not achieving much in the world of politics, Prkačin managed to remain in public spotlight by often appearing in various talk shows and being involved in Croatian entertainment industry. In 2011 Prkačin returned to Croatian Party of Rights.
In the fall of the same year, he was a member of the joint command of Croatian Defence Council and Army of Bosnia and Herzegovina. Three months later, Ante Jelavić said Prkačin had implicated him and accused him of being a former member of Yugoslav secret service KOS.
