[DC Universe] About Parademons...

So, one of their significant abilities seems to be infection of others to become Parademons. Any important heroes who has been turned into a Parademon in the past?

In most continuities they are made from the corpses of those who fight against Apokolips, although they are capable of converting living people into Parademons through slightly more effort. The exact process for this varies between continuities, but usually there's some sort of machine which converts the subject. Most Parademons are also augmented with additional technology. They can fly, use various Apokoliptan weapons, and breathe fire. In the New 52 they nearly converted Superman into a Parademon in their first encounter, but Batman managed to save him. IIRC there's one continuity where Parademons were created by fusing Motherboxes with people/bodies, essentially making each Parademon as strong as Cyborg.
