One major question is how well, and for how long, his alliance with outgoing President Joko Widodo, or "Jokowi", will hold.
On the campaign trail Prabowo has promised policy "continuity", but analysts say that is far from guaranteed.
"Make no mistake a President Prabowo would be his own president."
'UNCERTAINTY' ON THE CARDSIn contrast to Jokowi, Prabowo is from an elite family, the son of a prominent Indonesian economist and the ex-son-law of the country's former authoritarian ruler, Suharto.
Once his victory is officially endorsed, Prabowo will assume the controls of Southeast Asia's biggest economy on October 20.
