From the computer where you buy characters, red bricks etc. Go left, and you will come to
three chambers alongside each other with a interactive prompt in front. Choose your character and
change any one element of him/her, then save and exit to unlock the trophy.

*Glitched*

Must be completed in freeplay. Firstly you must unlock Bane whose Minikit is in Joker Getaway and costs 200,000. When entering a freeplay level choose Bane as your character, when you enter the level change the other character to any Batman and simply kill him with Bane to unlock the trophy. You may need to kill Batman with Bane multiple times for the trophy to unlock.

Once you begin freeplay, you may switch a character in your party for any other character you have bought who isn't currently in your party. When cycling through your party the right-most icon will be light blue S shape, select this to change to any character. Once you change character the trophy will unlock.

There is one soundbite per level for a total of 14. Please follow the collectables guide below
for the locations of each soundbite. Purchasing the soundbites is not required for the trophy, unlocking them will suffice.

*Glitched*

Must be completed in freeplay. Firstly you must unlock Commander Gordon whose Minikit is in Assault the VTOL and costs 80,000. With Commander Gorden use the button to draw your weapon and press it again to fire weapon. Once you hit and stun an enemy, quickly run over and press again for the trophy. You may need to kill an enemy multiple times with Commissioner Gordon's weapon for the trophy to unlock.

On several occasions in the Wayne Industries level you will be outside on various ledges where you will be attacked. Simply grab an enemy with and throw him towards the edge. Be sure to press when grappling him otherwise he won't throw the enemy off the side.

*Glitched*

Must be completed in freeplay. Firstly you must unlock Catwoman whose Minikit is in Arkham Estate and costs 100,000 studs. Once you are Catwoman and the other character is Batman, hold to enter stealth mode, then walk behind Batman and press to kill him and unlock the trophy. You may need to kill Batman multiple times with Catwoman for the trophy to unlock.

Go to the Batcave hub and go up to the area where you start the Justice League arena missions, from here jump and glide with Batman while moving to the right and just keep gliding until the trophy unlocks, you will have plenty of space available to get five seconds airborne so it shouldn't be any trouble.

To unlock true hero for a level, you must max out the stud meter at the top of the screen. The true hero amount varies per level. To achieve true hero keep your deaths to a minimum, break every object in sight and explore all areas of the level. The best area to achieve true hero is the first level where the true hero amount is only 40,000 studs, however if you wish you can do it on the final level where the amount is only 1,000 studs. Using a stud multiplier will not disable this trophy.

To stun an enemy you can either use a projectile weapon by holding with certain characters and targeting enemies or you can use the + combo to jump up and pound the ground to stun the enemy. In addition to that you can throw enemies into other enemies which will also stun them. All three of these methods count towards the trophy, just make sure to use them as regularly as possible in story mode and you will get the trophy fairly early in the story.

You can also jump on to a surface where enemies cannot reach you, then continually stun them from there with your projectile. A good area to do this is the start of the second level, jump up on the helicopter to the right of the first area and use your projectile to stun the three enemies below until the trophies pops. Thanks to Harry94 for the tip.

Self-Explanatory. This is a lego game and as such this is very easy. Most characters have regenerating hearts and most enemies drop hearts when they die. You should get this within the first couple of levels of story mode. The main thing for this trophy is to use your characters abilities, eg. if you are Batman use his Baterang to stun enemies then kill them. If you are have difficulty with this, I would recommend doing The Batcave mission, there are only a few enemies in the entire level and there aren't many oppurtunities to die.

There are five Justice League arenas, simply complete all five to unlock this trophy.

-Gotham Theater
-Gotham Metro
-LexCorp War Room
-Arkham Nightmare
-LexCorp Lobby

See Justice is Served for more details.

Below is a wave-by-wave strategy for all Justice League missions. The only factor in your ranking is the amount of lives that you use, for each level you must complete them within four lives for gold ranking.

Gotham Theatre
Wave 1: Grab each enemy and throw them into each other.
Wave 2: Use the + combo on the guys in the striped uniform, make sure you kill the guys with the guns as soon as possible and throw the remaining guys.
Wave 3: On this wave, use your projectile weapon to knock down the enemies from the air and as soon as the enemies are on the ground, grab them and throw them into the guys in the air.
Wave 4: There will be one enemy here with a gun, so kill him fast. For the rest of the enemies just grab and throw them.
Wave 5: In this wave you can grab and throw all enemies but be sure to avoid the explosive penguins. If you want you can throw enemies into the penguins to make them explode.
Wave 6: Almost the same as the last wave but there will be guys without hats on, these guys must be stunned first before you can kill them.
Wave 7: Do not destroy pillars as they will provide useful cover, from the start fire an arrow at the Joker on the right, then run to the right and fire the Joker on the left. Repeat these steps until they have died.

Gotham Metro:
Wave 1: Grab and throw each enemy but make sure you kill the enemies with guns first. Once the spiders come in use the + combo to kill them.
Wave 2: Move towards the center of the screen and go as far back as possible, wait for your enemies to come to you to avoid hitting the toxic pools.
Wave 3: The same as the last wave but use Aquaman to remove any toxic pools if you have the time and space.
Wave 4: Kill all the spiders use the + combo, kill the other guys by throwing them and if they grab you rapidly press or you will lose health quickly.
Wave 5: You will need to stun the Drill-head guys before you can grab them, kill the guys with the guns first.
Wave 6: The same as the previous wave but you will not be able to use throws near the Drill-head guys, so kill all the gun-wielding enemies first then move onto them.
Wave 7: Using the Flash, kill the enemies from left to right, position yourself directly to the left of each enemy so when the other enemies fire they will only shoot each other, once you kill the guy on the right dash back to the left again.
Wave 8: Ignore the guys in white and focus on Mr. Zsasz, when you can see him rapidly press , when he disappears use the Sensor Suit Batman to find him again and use your combos again. Repeat until he is defeated.

LexCorp War Room:
Wave 1: Simply grab and throw all enemies.
Wave 2: Same as the last wave, but watch out for the electric current, it will move clockwise around the pylons.
Wave 3: Very easy wave, walk to the top right square and then run around the area on the squares at the edge, don't use super speed as you may accidentally get electrocuted and you will be insta-killed.
Wave 4: Target the flying enemies with your projectile weapon, once they are on the ground use the + combo and then grab and throw them into other flying enemies.
Wave 5: This consists of three mini-waves, target the top two guys on each wave as they have rocket launcher, then focus on the bottom two. You won't be able to grab and throw here, so just rapidly press .
Wave 6: In this wave a grid of lasers will come across the screen every 6 or 7 seconds, these lasers will insta-kill you so watch out, the best way to do this wave is to kill one guy, then jump over the lasers and move as far right as possible, by the time the lasers come back to the right they will have turned off so you only have to jump over them once each time, repeat those steps for the rest of the wave.
Wave 7: Focus on Mr. Freeze and ignore the other enemies, position yourself so that the guy with the gun can't shoot you and will instead hit Mr. Freeze.

Arkham Nightmare:
Wave 1: Focus on the guys with the orange uniforms first, then go for the guys in white.
Wave 2: Very easy wave, use the + combo on the spiders, then grab and throw the skeletons
Wave 3: Another very easy wave, simply grab and throw all enemies.
Wave 4: Grab and throw all enemies while making sure to steer clear of the fire
Wave 5: Stun all the guys in white, grab and throw the orange guys. There will be one guy with a gun, kill hm quickly.
Wave 6: Grab and throw all the skeletons. Steer clear of the moving kryptonite.
Wave 7: There will be four Jokers in this wave, one of them will have a gun. The objective here is to get the gun-wielding Joker to shoot the
crusher-thing which comes down from the roof, to do this stand still towards the middle and once you see the reticule stop moving, move away. Once
the crusher is down stand directly behind so any bullets fired at you will hit it and not you. Repeat those steps until it is destroyed.
Wave 8: For the first part use the + combo on the spiders. In the next part focus on the long arms on each side, both of them will die in five hits.

LexCorp Lobby:
Wave 1: Stun all enemies using + , once they are stunned grab and throw them into other enemies.
Wave 2: Very similar to the Wonder Woman wave in LexCorp War room, knock the enemies down with your projectile, stun them and then throw them.
Wave 3: Be careful of the laser in the center, each time you see it emerge fly up in the air and keep moving in the air until it has stopped, when you are on the ground, grab and throw the enemies, stunning them is not necessary.
Wave 4: Very easy wave, when the helicopters come down aim your laser at the gold part on the choppers, there are only three to destroy, the third will come from the left when the first two are destroyed.
Wave 5: Avoid the laser, jump over it when the lower laser comes to you. Grab and throw the enemies as usual but stay aware of the lasers.
Wave 6: Fight the enemies from left to right. Stand directly to the left of each enemy to avoid getting shot by the others. The Flash cannot stun
enemies so just use for combos. BEWARE: when walking to the next area, there will be a big hole just in front of you, be careful not to fall into it.
Wave 7: Here you must fight the LexCorp Receptionist again, when it starts firing rockets stand directly to its right and it won't be able to shoot you, once it stops hit the bullseye. The fight is exactly the same as the story mode fight.
Wave 8: Here you must defeat a wave of enemies with Superman, you will need to stun the guys with the guns, you can grab everyone else without stunning them. In the next part you will have to defeat a boss which is identical to the final boss in story mode, you will have access to
eight JLA characters but you will only need Superman and Power Suit man. After avoiding gunfight, destroy the gold plate with Superman. When he comes back down, if you are quick enough you can fire a bomb with Batman without giving him a chance to fire. Repeat this step to defeat the boss.
