LIMITED PACK GX: Ra Yellow
Dark Tyranno

Etymology and trivia
Dark Tyranno is a counterpart to Black Tyranno—another Dinosaur-Type monster with a similar name and direct-attacking effect.
Dark Tyranno was created for the Yu-Gi-Oh! GX anime to replace Black Tyranno, likely due to the latter's direct-attacking effect being more restrictive than intended.

Rex Bomber
Arcana Force XII - THE HANGED MAN

Etymology and trivia
THE HANGED MAN is based on the tarot card of the same name.
Its tails effect being the positive one—contrary to most other Arcana Force monsters—is reflective of the Hanged Man appearing upside down in its card artwork and thus being upright only in its reversed position (represented on this card by getting a tails for its coin-tossing effect).
Candelado, the Phantom Beast of Light
Etymology and trivia
Candelado is a twist on candela—the SI unit of luminous intensity, which measures the luminous power per unit solid angle emitted in a particular direction.
Phantom Beast of Light (Kōgenjū) is a pun on the Japanese term for "light source" (also pronounced as kōgen)—but with the second kanji instead being the gen meaning "phantom" or "mythical."
Attack name
Death Shining
White Knights Lord
/Lord of the White Knights Order
Etymology and trivia
White Knights Lord has somewhat similar effects to Phantom Beast Rock-Lizard—a trait shared by the other White Knights monsters in the anime and their Phantom Beast counterparts.
Its Special Summoning effect is a reference to the anime Trap Card The Sealed Gate—which was used to summon it in the anime.
The Undying Death-Lord
Etymology and trivia
The Undying Death-Lord's effect to predetermine the top cards of the player's Deck, including the ability to place Certain Kill in a Single Strike! Iai Draw on the very top, if needed, is a reference to how this card's user in the GX anime, Ikkaku Tachibana, made a deal with the Shinigami that bestowed him unnatural drawing power and the ability to ensure a second Iai Draw would be on the top of his Deck after activating the first one—guaranteeing him a one-turn kill against his opponent.
