Cheaters never prosper. Except in video games.

In "The Lego Movie" video game, you can unlock hidden characters through hard work, or the easy way, using cheat codes. So, here are the complete list of characters and their respective codes from IGN. To unlock them, simply pause the game and enter the "Extras" menu then select the "Enter Code" option.   

Abraham Lincoln (F3VG47), Cleopatra (P4YX22), Emmet-Clown (FNHLTK), Emmet-Lizard (UOOAQY), Emmet-Pajamas (HJ4C21), Emmet-Old West (NIHX2B), Gallant Guard (FXP9AN), Green Ninja (OSSVNI), Lady Liberty (A76DN7), Larry The Barista (K7TDXJ), Lord Vampyre (KGJ4DU), Mrs. Scratchen-Post (UP7HJQ), Panda Guy (NG73OM), Prospector (FHNCD1), Robo SWAT-Laser (GFH2F8), Shakespear (31S3I5), Swamp Creature (BID12F), Vitruvious-Young (BC2XJ5), and Yeti (V4P96P).

In the game, characters can also change their pants to gain various abilities. To unlock secret characters and new pair of pants, go to Bricksburg and find the big LEGO kit floating near the left side of the police station. Walk up to it and enter the codes for the characters and the pants.

The unlocked characters can be viewed at the bottom portion of the "Character Select" screen. As for the new pair of pants, you can try them on at the pants closets or Dispantsers located in each hub world. Here are the secret characters and their respective codes:

Angry Kitty and Construction Pants (6LK78NN9 or HVLH63VL), Blacktron Fan and Musical Pants (6LKMNDHR or HVLLRX6R), Johnny Thunder and Super Secret Pants (6LK3FRL6 or HVL4TQT4), and Robo Pilot and Astro Pants (6LK3RRY4 or HVL4TB94).

Aside from using cheat codes, the hidden characters in the game can also be unlocked by buying them using your Studs. To collect more Studs and gain new abilities, players can look for special items in the game such as Red Bricks, Golden Bricks, Gold Manual Pages, and Pants. Searching for these items can be a bit tricky. Fortunately, Gamesradar posted various articles that can assist you in locating these special items.
