One-Winged Angel: After Bosch stabs him in the neck, Ryu transforms into his dragon form for the first time. He can transform into it in any subsequent battle, but doing so will quickly max out the D-Ratio.
Power Limiter: The counter serves as a counter for how long he has to live before Odjn's power overwhelms him. Using his dragon abilities causes it to go up quite rapidly.
Almighty Janitor: His D-Ratio is 1/8192 but he ends up beating people with D-Ratios over 1/64.
Ranger: Is a low-ranking member of the Sheldar Rangers.
Sanity Slippage: Bosch's sanity takes a hit when Ryu transforms into a monster and kicks his ass after getting stabbed in the throat, and just gets worse as the game goes on.
Trauma Conga Line: During his We Can Rule Together speech, Bosch outlines his plans for the future to Ryu. Then Lin blows up the train they're on, he's told to destroy the cargo they were transporting at all costs, gets his butt kicked by Ryu's dragon form, and watches his boss get killed in from of his eyes. Even after he replaces almost half his body with a D-Consturct he still can't keep up with Ryu.
Tron Lines: The D-Construct is covered in blue lines.
We Can Rule Together: Makes the offer to Ryu early in the game, but seeing how he stabbed Ryu in the throat when they next met, the offer was retracted.
Asskicking Equals Authority: Elyon became head of what would become the Regents by kicking Deamoned's ass when he was still a Chosen of Odjn.
The Chessmaster: Almost everything in Sheldar ultimately boils down to The Plan of some sort by Elyon. The entire establishment of the D-Ratio system and the Regents, the plan to have Ryu become a Chosen of Odjn, and the backup plan of the People Jars full of headless Nina clones...
She's a Man in Japan: Gender-bended for the US release because of hir implied relationship with Elyon.
Knight Templar: He trains Bosch literally from toddlerhood in gladiatoral combat—because he feels it's a necessity to protect Sheldar from rogue Genics, including and especially the D-Constructs. It's also very strongly implied that he killed everyone who bonded with a D-Construct from the time Elyon bonded (and was rejected) by Odjn up to when Ryu became a Chosen.
Last Disc Skill: One of Ryu's best level 3 skills, Terabreak, is stolen from him.
Scars Are Forever: He lost his left eye to an Odjn-ridden Elyon. He was so impressed by this that he stuck around.
La Résistance: Is the leader of the official resistance to the government.
Really 700 Years Old: And now we really want to know what sort of life-extension technology the Regents have...
The Dragon: It's revealed he is this to Elyon, of all people. It's strongly implied that Trinity is in fact a faux La Résistance designed to allow Sheldar's inhabitants to rebel without threatening the Regents and Elyon's plan.
