Emmet Brickowski/Rex Dangervest

Emmet Brickowski, later known by his future counterpart Radical Emmet Xtreme "Rex" Dangervest, is the major protagonist of The LEGO Movie and its sequel The Lego Movie 2: The Second Part, as well as the main antagonist. Emmet started off as an average every-day person who turned into a master builder after touching the piece of resistance. Both iterations are voiced by Chris Pratt.

Overall

 * 1) Both incarnations of Emmet are well designed.
 * 2) Chris Pratt does an excellent job voicing them.

Emmet

 * 1) His character is kind of like the misunderstood protagonist trope, but it had a clever spin to his personality, making him likable and memorable.
 * 2) He is very optimistic and sees the positive in situations.
 * 3) He was at first misjudged for being an idiot by all the master builders, but it turns out that his plans actually do work.
 * 4) He helped reformed President/Lord Business by telling him that he doesn’t have to care about himself and should care for others.
 * 5) He learns that  being a self believer makes him special.
 * 6) Emmet has great relationships with his friends, Lucy, Batman, Vitruvious, Benny, Metal Beard, Unikitty, and many others.
 * 7) * He may have expressed jealousy towards Batman at first, but he has learned to grow towards him.
 * 8) He sacrifices himself to save his friends from getting destructed.
 * 9) He is also very funny most of the time as well.
 * 10) Near the end of the film, he becomes a true master builder to save his friends.

Rex Dangervest

 * 1) Unlike the original Emmet, who's optimistic, heroic, and an idealist, Rex is the polar opposite. He serves as a much darker counterpart who was once as hopeful and positive has now turned into a vengeful person, and thought he was abandoned and betrayed by his old friends, and was told by Lucy to change his ways and toughen up.
 * 2) Even before his true motivations were revealed, Rex still remained optimistic when he first met his past self.
