|“||Only the toughest can get out of there alive!||„|
|~ Rex Dangervest.|
Rex Dangervest is the main antagonist of the 2019 animated film The LEGO Movie 2: The Second Part.
He is a galaxy-defending archaeologist, cowboy and raptor trainer, who appears to be a benevolent ally, but is later revealed to actually be a resentful version of Emmet Brickowski from a future timeline. His true intention is to bring the "Armamageddon" upon all of his kind, as revenge for being abandoned and forgotten.
While he was still Emmet Brickowski on a mission of saving his friends, Rex crashed his spaceship into an asteroid field and wound up under a clothes dryer (or Undar of the Dryar System) in the real world. After seeing all his friends continue to go on after his supposed death, Emmet became filled with hate and grew resentful towards them by trusting in only himself, changed his clothes and name, and built a time machine so he could travel back in time and ensure the "Armamageddon" occurred.
Rex saved Emmet as he was about to crash into an asteroid field and teamed up with his past self to venture to the Systar System and save his friends from the DUPLO Aliens. As they continue on to the Systar System with some of his raptor buddies, Emmet begins to take on several of Rex's mannerisms, hoping to impress Lucy. When they arrive, they evade capture by Wa'Nabi's forces by swamp creatures and "brainwashed" of most of the people by singing "Catchy Song".
Once they escape for the DUPLO Brickyard, Emmet is reunited with Lucy and they embrace, but not so much when she meets Rex. Rex tells Emmet that he has managed to have his own abilities and force by making him tough. Despite Emmet's joy of this by impressing her, Lucy is sort of disappointed by this. They make up a plan which involves switching off the pop music that is brainwashing the others, while Emmet will destroy the reception cake encased in a temple to stop the wedding between Batman and Wa'Nabi. However, Rex and Emmet are shocked when Lucy reveals her original hair to them, and she affirms she is not brainwashed. Despite Rex's warnings, Emmet believes she is the real Lucy because he trusts her, and she helps them to the plan.
|“||(Emmet: You tricked me into hurting my friends) I didn't trick you. I taught you to harden your heart, just like you asked me to.||„|
|~ Rex explains what he did|
After Finn and Bianca put away their LEGOs in a storage bin, Emmet tries to stop them but is prevented by Rex revealing his true colors as Emmet's future self and reveals that he traveled back in time to ensure the "Armamageddon" would happen.
|“||I can't… (Emmet: What do you mean?) She came back for ya. You're never going to turn out like me, which means I'm never going to exist.||„|
|~ Rex refuses to join for his existence, and accepts his fate.|
Lucy then tells Rex that Emmet will not become like Rex did, but Rex can be like Emmet as they ask him to join them, but Rex denies since he realizes that Emmet being saved by Lucy means he didn't end up becoming what Rex did, erasing his timeline and causing the deluded time-traveler to begin disappearing limb by limb. Accepting his fate, Rex tells Emmet to always be upbeat and thanks Lucy for saving both of them, saying his last words: "Besides, this is a pretty righteous way to go out, no regrets! Except again not trademarking "No regrets", that was a mistake, one love!" before fading completely from existence.
Rex's ultimate fate is unknown. Although he may have "died" in the narrative of the LEGO universe, it must be taken into account that Rex's motivations were all just a figment of Finn's imagination, which mirrored his real-life altercations with his sister. His existence as a physical LEGO mini-figure is likely still intact in the human world, as the rate of decay when he died in the LEGO universe was greatly over exaggerated.
- Queen Watevra Wa'Nabi and General Sweet Mayhem were marketed as the main antagonists of The LEGO Movie 2: The Second Part. However, it was revealed that Rex would be the main antagonist, even though he appeared as a supporting character and ally, but his true intentions were hidden in all promotional and marketing material.
- Rex's occupations are references to past roles that his voice actor Chris Pratt has played in his acting career.
- Archaeologist; a reference to a rumor that Chris Pratt would portray Indiana Jones in a reboot.
- Cowboy; a reference to Joshua Faraday in The Magnificent Seven.
- Galaxy Defender; a reference to Peter Quill/Star-Lord in the Marvel Cinematic Universe.
- Additionally, Rex makes a reference to how he has a chiseled jawline hidden under baby fat. This is more likely than not a reference to Chris Pratt's career prior to his breakthrough in 2014, where he was significantly overweight. He lost this weight while undergoing intense training for his role as Peter Quill/Star-Lord in Guardians of the Galaxy.
- Raptor Trainer; a reference to Owen Grady in the Jurassic World duology.
- While explaining his motivations, he claims that he rescued his raptors from a volcano explosion. This is a reference to the first act of Jurassic World: Fallen Kingdom.
- Additionally, he also is partially influenced by Pratt's other roles, as Andy Dwyer in Parks and Recreation, and Scott Hatteberg in Moneyball.
- According to Rex himself, his occupations also include: Social Media Influencer,First Baseman,Man of the Soil and Script Doctor, these were mentioned when he meets Wyldstyle.
- He is the first (and so far the only) villain in The LEGO Movie franchise to ever die, as far as the LEGO universe narrative is concerned (taking in mind that the film's events in regard to Rex's time-travel twist were all in Finn's head). Given what his goals are, Rex is also the darkest villain in the franchise, yet he has redeemable traits, unlike Risky Business.
- Rex is one of the few characters who breaks the fourth wall and mentions movies like Matrix and Back to the Future before he dies.
- His name stands for Radical Emmet Xtreme.
- Emmet and Rex share similar vest patterns, but in different colors (Emmet's in bright orange and very light grey, and Rex's in earth blue and dark stone grey). They both don a bright blue undershirt, and share the same quiff in their hair.
- When Rex and Emmet are being "attacked" by Plantimals in the forest, Rex shouts "Pew!" each time he fires, likely a reference to The LEGO Batman Movie.
- The name of one of Rex's velociraptors (The Other One) may be a reference to "The Big One" from the first Jurassic Park movie, seeing as how they are both velociraptors and their names both start with the words 'The' and end with 'One'.
- All the other raptors have names that reference science-fiction movies. Ripley is named after Ellen Ripley, the heroine in the Alien series, and Connor is named after John Connor, the Resistance leader in the Terminator franchise.
- Rex's surname, "Dangervest", is a reference to the fact that Emmet, who is a complete opposite of him, wears a safety vest.
- He stated that his middle name is "Machete Ninja Star".
- One of his quotes "It's time to put away childish things" is possibly a reference to 1 Corinthians 13:11. "When I was a child, I talked like a child; I thought like a child; I reasoned like a child. When I became a man, I put the ways of childhood behind me".
- Besides his occupations, he also likes building furniture, busting heads, and having chiseled features previously hidden under baby fat. Ironically, he is a Master Breaker, despite claiming that he builds furniture, where Emmet is a Master Builder.
- His ship the Rexcelsior is shaped like a bunched fist.
- Had he ACTUALLY ripped Emmet's body apart, Rex would have also been destroyed.
- Rex made a cameo appearance in a Turkish Airlines Safety Video promoting the film.
