If you haven't played LEGO Batman 3: Beyond Gotham yet, you don't know what a crazy ride you're missing. If you have played it, well, let's be honest... There's no way you've gotten to 100% yet. It's just impossible, in a game of this size, to complete it fast.

There are over 150 playable Minifigures in LEGO Batman 3, all of them plucked from DC Comics history and continuity. It goes without saying that there are plenty of obscure characters in that enormous catalog, but there are some longtime fan-favorites as well.

Here are ten of the most desired DC characters that you'll want to play as, and what you have to do in the game to get them.

The Atom

Getting your virtual hands on the Atom is a big deal in LEGO Batman 3. Throughout the Free Play hubs and worlds, you'll run across elaborate rat-maze contraptions that only someone very small can access. Don't bother trying to use Brainiac's shrink ray to shrink down another character to enter the maze; the effects of that gun only last for a few seconds.

You can always unlock the "Mini Characters" Red Brick, which turns all of your characters that small, but it's a pain to go back and forth to the Extras menu just to turn it on, and then do the thing, and then go back to turn it off, etc. The easiest and quickest way to access those small areas is with the Atom, who can shrink at will.

The Atom can be acquired during the level "The Big Grapple," but only in Free Play mode. After escaping the big green dome bubble with Plastic Man, go around to the open area between Green Lantern (who's still being mind controlled by Brainiac) and the dome. Destroy the three silver items there and then build with your brand new LEGO bricks.

This triggers a grappling hook to the left, so go to it and grapple and it creates a bunch of green toxic goop all over the floor. It also creates a hovering cleanup vehicle, which you should use to mop up the goop. Next, go park your hovering vacuum car over the contraption you built a minute ago with those exploded silver pieces. Two levers pop up; pull them and there it is: the Atom character token.

Black Adam

In the Watchtower, go to the Trophy Room. Fly up to the platform on the right side of the room. Use Brainiac to shrink the statues, and shazam. (Sorry.) There's Black Adam's token.

Deathstroke

Deathstroke can be found in the "Big Trouble in Little Gotham" level, and is easy to get regardless of whether you're in Story Mode or Free Play. In the second area, where Flash and Joker team up to fight bad guys at Joker's carnival, look for five fireworks spinners. Use a grappling hook to pull on each one, and after they've all gone off, you're rewarded with Deathstroke's character token.

Doomsday

From the Hall of Justice hub, jump down the big hole into the Hall of Doom area. Outside the Hall of Doom is a swamp area where you'll find a long row of mushrooms growing. Look for the mushroom that has a circular, glowing gate around it. That's right: it's a race. Just follow the gates and jump on each mushroom in turn, and you'll get Doomsday's token as your reward. You'll want to have plenty of coins saved up for Doomsday; at 1,250,000 coins, he's one of the most expensive characters in the game.

As long as you're at the Hall of Doom, you might as well go ahead and get...

Harley Quinn

Go inside the Hall of Doom and work your way through the various character quests until you get to one called "Five Studs Please," in which Ms. Quinn herself gives you a mission. After you've spoken to her, several patients will appear inside the Hall of Doom. Go and speak to each one in turn, and then have them follow you to Harley. She'll give you her character token as your reward.

Kilowog

Kilowog can be found as you enter the big temple in the "Need for Greed" level. Pull down the big pillar and then look for a birds nest with 3 eggs inside. Destroy the eggs and then destroy the big bird that appears. Claim Kilowog as your prize (if you can get past the baby bird murderer guilt).

Lobo

While Free Playing in the London part of the "Europe Against It" level, look for the wrecking ball near the bus. Have Brainiac shoot his blaster at the wrecking ball, and it will grow bigger. That's all you have to do. The wrecking ball falls on its own onto a boat, which dispenses Lobo's token.

Reverse Flash

In the "Space Station Infestation" level, fly up and look on the right of the armory. There's a missile here that Brainiac can shrink. Destroy the crate that appears and then fly back up to nab the character token for Reverse Flash. While you're in this level, you can also get...

John Stewart

During the Firefly boss fight, go around to the left of the spot where you started in this area. Look for a blue grate above you and use a power suit equipped with magnetic control to open the grate. Switch to a flying character (or suit) and soar up into the grate to get John Stewart's token.

Swamp Thing

Swamp Thing is one of the characters that comes in more than one flavor. You have your original Swamp Thing, and then there's the New 52's version of Swamp Thing. Let's grab them both.

The fourth character quest that becomes available in the Hall of Doom is called "The Garden of Love." It involves going outside and helping Poison Ivy out by putting out some fires. Have her follow you all the way around to the left of the building and Swamp Thing will be waiting for her there. He'll give you his own token when you hand her over.

The New 52 Swamp Thing is found on the Orange Lantern homeworld, Odym. Leave the main village and look for a collection of small huts. Destroy the crates there, then blow up the sliver lock that appears. Go inside the hut and you've got the token.
