Nobody can give you a reasonable answer without knowing what size tank you have.
If the tank is under 60 gallons - nothing, the Oscar should be kept solo or somebody will get hurt when he gets bigger.
If the tank is 60-100 gallons - the best choice would be a mate for the current Oscar. Of course, this doesn't mean just buying another one, it means going through the motions of establishing a pair, something that can be explained if you have any interest. A Pleco is usually a safe bet too, but get the Pleco larger as they grow much slower then Oscars.
If the tank is over 100 gallons then your options open up considerably. Now there are a few things you can do. A mate is still a good option, or you can do a mixed cichlid tank with other aggressive cichlids (I don't recommend it because Oscars are actually push-overs compared to other similar sized cichlids and tend to get hurt, plus cichlids are naturally territorial and this is an unnatural environment for all the cichlids involved, and at some point aggression issues always develop). You can also go with a schoal of a large and tough fish that the Oscar can't eat and won't find a threat (and therefor will mostly leave alone) like Tinfoil Barbs, Silver Dollars, and larger sized catfish. And, of course, a Pleco will usually work.
In a 5' 110 gallon tank I kept one Oscar with 4 Tinfoil Barbs and a large Royal Pleco and it was a nice and active tank with little aggression.

I had a Convict. It worked out great. The Convict was smaller but the Oscar never bother it. I have also had a Goldfish and it do well. An Algae Eater Plecostomous? Not sure of the spelling. When I introduce a fish to my Oscar tank, I remove the Oscar and rearrange things and add the new fish. Then put the Oscar back. They think the other fish there first and usually leave it be. Just be sure to keep the Oscar fed. Hunger drive them to eat whatever move.

Some good tankmates would be Jack Dempseys, Convicts and parrot cichlids, of the same size of course. Just make sure your tank is big, as all these fish are going to get BIG. HTH

plecos as long as they are about the same size you can also put in other oscars or parrot cichlids

Red belly pirahana, sharks if same size or larger. Rule of thumb with cichlids are to start with same size and to grow same size.
