- The Medbot Action Package has an image of Claptrap flanked by two doves while holding a bloody bone saw and floating health crosses. He also moves faster and fires a healing laser beam to restore health to his allies, making it one giant nod to Team Fortress 2 and The Medic class.
- In the character select screen, his fighting style is described as "It's not stupid, it's advanced!"

Until you are dead." Furthermore, the Meteor Slam upgrade uses the Terminator post-timetravel crouch as its icon.
- The last ability on Wolf's skill tree uses a modified Top Gun quote for its description.
- Wilhelm is actually religious, making references to the deity he worships throughout the game. His god is the Almighty Robotic Policeman.
In the short form, every single thing that references the name "Jack" gets a nod in his heads and skins. Including nursery rhymes, slang and aphorisms.

- In the preview video that has Mr. Torgue and Sir Hammerlock giving a very detailed breakdown of all the characters, enemies, environments, new features, new weapons, and story has Torgue straight up point out the various internet memes found around the game. BECAUSE REASONS! Then he says he's just kidding. They blew the F$@& out of the meme references in BL2 because of how lame they are. The video then references Doge.WOW. SUCH MEMES. VERY REGRET.
WOW. SUCH SCARES. VERY HORROR.
- In the magazine racks in Concordia, there's a pamphlet to visit the Echonet Meme Graveyard.

- The boss RedBelly is based on Master Blaster from Mad Max Beyond Thunder Dome, with a huge guy serving as the body and a dwarf serving as the head.
- This is a bit of a twofer as the two also serve as a reference to infamous and legendary Australian outlaw Ned Kelly. One ECHO log for the pair has Belly mentioning that he forgot the leg portions of their armour (Ned Kelly's famous armour lacked any protection for his legs. The police disabled him by shooting there when they successfully captured him).This is even the best place to hit him during the boss fight!
- There is an entire mission dedicated to escorting C-3P0 and R2-D2 expies (named RT-FC (Read The Fucking Code) and ICU-P] (I see you pee) to deliver safely deliver a message to Toby Van Adobe.

- The name of the recipient could also have been a reference to current Australian Prime Minister, Tony Abbot.
- There is a side quest giver called Sterwin, a parody of Steve Irwin, who talks and looks almost exactly like him. In this case, he's an indoors office worker who's been mysterious sent outdoors to capture Eridians, and can be used to unlock a further quest where you capture them to be put on a preserve, because all they want to do is "play around, not hurt people."
- During both of these quests you have to capture Eridians using a grenade mod that functions like a Poké Ball (and looks like a Quick Ball.) You have to lower their health first and everything. The descriptions for the filled balls are also full of references to Pokémon. The mission completion text points out how you were the best, like no one ever was."Congratulations, OPHA was caught! Want to give it a nickname or something?"

- A mission in Helios's Research and Development area involves receiving a weapon from Claptrap expies of HAL-9000 and SHODAN: CLAP-9000 and DAN-TRAP. The first is friendly and has a soothing voice. The second constantly boasts about the perfection and beauty of destruction and has a stutter.
- As an added bonus, the robot you choose to disable will quote the same dying lines as the AI they are an expy of, and the surviving bot will give you a weapon which references the AI they are based on. For example, DAN-trap's reward is called the Mining Laser, which is a reference to the mining laser SHODAN took control of in System Shock.
- The CLAP-9000 says Hal's famous line "I'm afraid I can't do that," and replies to a line from DAN-TRAP with "Nah," referencing the ending to System Shock 2.
- One of Janey's nursery rhymes is a word-for-word parody of Avatar: The Last Airbender's opening."Long ago, the Scav nations lived together in disharmony. Then everything changed when Zarpedon attacked. Only the Vault Hunter, master of guns, could stop her. I believe the Vault Hunter can save the moon...Cue intro music. Spoilers !! It happened pretty much like that, actually."
- There is gang of scavs called the Darksiders. Their emblem is a transparent prism splitting a beam of light. Elpis is a moon. Right?

- You may occasionally hear a Scav yell *You no take candle!".

- Upon meeting the Skipper's true AI form, she says 'Yank me', much like Cortana does in Halo.
- After killing some Scavs in the prototype powersuit, Felicity will remark "everything lost, like tears in a puddle...
- Her boss form is entitled "Felicity Rampant," and the Boss Subtitles are "If Only Elpis Had More Time." Huh. A mad AI that goes mad due to a time limit? Sounds familiar...
- The use of rampant is itself a shout out to both games. The process of rampancy originating in Marathon, specifically dealing with an AI processing not being human and wanting to have an actual life outside of what it was built for. Which is exactly whats happening to Felicity.
- Her boss form is entitled "Felicity Rampant," and the Boss Subtitles are "If Only Elpis Had More Time." Huh. A mad AI that goes mad due to a time limit? Sounds familiar...

- In Serenity's Waste there is a unique kraggon tied to a Badass Challenge. Its name is Phonic and it's the only Shock-element Kraggon in the game, giving it a blue colour. Kraggons in general like to attack you by curling up into a ball and rolling into you. What does "Phonic" rhyme with again?
- In TVHM, it is replaced by a gold-colored Phuper Phonic Kraggon.
- After doing Cosmo Wishbone's sidequest, Niel Parsec will try to jump off the balcony only to fall after several feet of flight.

- Captain Chef is a reference to James Cook, more commonly known as Captain Cook, who first established a colony on and mapped large parts of Australia (and ultimately met his end after angering a crowd of Hawaiians). Much like Cook, Chef is oblivious to the outrage of existing inhabitants (in Cook's case, the people indigenous to the continent) and apparently unaware the place has already been discovered (in Cook's case, multiple landings were made on the Australian continent by other countries, they just either sank or didn't bother staying there). His quests might also be a reference to the Flagstaff War.
- Davis Pickle's name is a reference to Travis Bickle of Taxi Driver.

- The sidequest The Empty Billabong is one long reference to the Australian song Waltzing Matilda, including the Jolly Swagman, Billabong, Jumbuck (which gets shoved in a tucker bag), reference to the Swagman "boiling his billy", coolibah tree, and that fact that you find Swagman's recording after he's dead, meaning you are effectively hearing his ghost.
- The bonus objective from Space Slam which requires you to be on fire is a direct reference to NBA Jam, where outstanding performance would light you and the hoop on fire. To complete the reference, Tog even says "He/She's on fire!" in the exact same cadence as the Jam announcer.
- Lost Legion Sergeants are a twofer for Warhammer 40,000, as their loadout of a pistol and sword is very commonly used by squad leaders in the grim, dark future. Additionally, their hats and body armor make them dead ringers for Knight-Commander Pask and Cadian captains in general.
- The Laser Disker is one big reference to Tribes, since its flavor text is the popular "Shazbot!" text taunt, and the weapon behaves exactly like the iconic Spinfusor, being a gun that fires explosive energy discs.
