what do i do next ?

You can always follow the ghost studs to the next mission from anywhere in the city. They'll go straight down the middle of the street and lead you right to the bat symbol that starts the mission.

You go to the red light signals (which are the depots to access the Map and Vehicle lists). Once you activate those, they turn into a blue signals. Each red light signal has an character attached to it. I found this out after tons of hours into the game.

Other than that, you unlock by progress in the story and other ways such as collecting LEGOs.

I was wondering how you get the villians to appear on the map? The only two I see on mine are Sinestro and Boomarang. How exactly do I get others to show up on the map? Is it through normal story progression?

The Bat Symbol. Go to it, you will start the next story mission. I believe this is the mission with that tram going around the block. You have to go to the teleport device within the area of the tram. Actually, that may have been mission 6. Mission 7 should
start once you go to the Bat Cave and open up the main teleport device.
