Card Trivia:Junk Warrior
- This is the cover card for Starter Deck 2008/Starter Deck: Yu-Gi-Oh! 5D's, Duelist Pack: Yusei, and is also one of the cover cards for Structure Deck: Synchron Extreme/Synchron Extreme Structure Deck, Animation Chronicle 2023, and Maze of Millennia.
- This monster appears in the artworks of "Clashing Souls", "Dimension Voyage", "Give and Take", "Scrap Fist", "Speed Spell - Synchro Return", "Synch Blast Wave", "Synchro Chase", "Synchro Deflector", "Synchro Gazer", "Synchro Spirits", "Synchro Strike", and "Urgent Tuning".
- The artworks of "Synchro Strike" and "Urgent Tuning" suggest that this monster was intended to specifically use "Junk Synchron" and "Speed Warrior" as Synchro Material. This is reinforced multiple times in the Yu-Gi-Oh! 5D's anime where this monster was Synchro Summoned using "Junk Synchron" and "Speed Warrior" as material.
- This card's second artwork is based on a scene from Yu-Gi-Oh! 5D's episode 1: "On Your Mark, Get Set, DUEL!" showing this monster being Summoned.
- This is the signature card of Yusei Fudo in the Yu-Gi-Oh! 5D's anime, along with "Stardust Dragon".
- This monster's effect to gain ATK from Level 2 or lower monsters controlled by the player reflects how Yusei draws his strength from his friends.
- This is the first and last Synchro Monster to be Synchro Summoned in the Yu-Gi-Oh! 5D's anime.
- This is also the featured card of the first and last episode of the Yu-Gi-Oh! 5D's anime.
- This is the first Synchro Monster to require a specific Tuner monster for its Synchro Summon, as well as one of the first Synchro Monsters to be released in the TCG, alongside "Gaia Knight, the Force of Earth" and "Colossal Fighter".
- This is the first Synchro Monster to be released in Starter Deck 2009 with Common as its rarity.
- This monster is similar to "Elemental HERO Flame Wingman", a monster used by Jaden Yuki in the Yu-Gi-Oh! GX anime.
- Both monsters were initially the signature cards of their respective anime's protagonist before they acquired a new signature card with an original ATK and DEF of 2500/2000.
- Both monsters were Summoned from the Extra Deck and used to defeat their opponent's monster with 3000 ATK in the first episode of their respective anime.
- In Bonds - Kizuna, the first opening theme song of the Yu-Gi-Oh! 5D's anime, the words "JUNK WARRIOR ATK 2300" are briefly displayed from inside Yusei's helmet visor; this is one of the few opening song details that is retained in the international release of the anime.
- After Yu-Gi-Oh! 5D's episode 102: "The Edge of Elimination, Part 3", this monster did not appear for 52 episodes until it was Summoned in the final episode, Yu-Gi-Oh! 5D's episode 154: "Shining Forth to the Future", when it was used to defeat Jack Atlas.
- During the final episode, this monster destroys "Red Dragon Archfiend" by battle, which can be interpreted as its payback after it was destroyed in battle by "Red Dragon Archfiend" in Yu-Gi-Oh! 5D's episode 2: "Creepy Crawlies".
- This monster bears a strong resemblance to Eightron from the anime DT Eightron (both have a football shaped head, made from trash, wears a scarf and are melee combatants.)
- This monster's signature attack, "Scrap Fist", was directly homaged in the first episode of the anime Senki Zessho Symphogear G, in which protagonist Hibiki Tachibana enlarged her right arm and engaged a set of brass knuckles, then rocketed forward with boosters on her back and a scarf trailing behind in a fashion identical to the typical stock footage of this monster. The two series have the same director, Katsumi Ono.
