- Ascended Meme:
- In perfect modern Treehouse/8-4 tradition. The "Classic" (Shulk) option (and a couple of others, like the Rebel option) for Rook will, in fact, mention "really feeling it" during combat.
- An early NPC asks you to "Please understand" about the delay in getting the West Gate open.
- All-Star Cast: For a J-game that doesn't use all-union talent, the English language track features a wide variety of VAs, such as Caitlin Glass, Cassandra Lee, Carrie Keranen, Michael Sinterniklaas, Matthew Mercer, Patrick Seitz, Cindy Robinson, Kirk Thornton, Mela Lee, Kaiji Tang, D.C. Douglas, Doug Erholtz, Josh Grelle, Cherami Leigh, Alexis Tipton, Kira Buckland, Robbie Daymond, Benjamin Diskin, Erin Fitzgerald, Kate Higgins, Yuri Lowenthal, Mary Elizabeth McGlynn, Bryce Papenbrook, Tara Platt, Keith Silverstein, Cristina Valenzuela, Dan Woren, Brian Beacock, Lauren Landa, Erica Mendez, Christopher Corey Smith, Julie Ann Taylor, Kyle Hebert, Stephanie Sheh, Christine Marie Cabanos, Wendee Lee, Amanda Céline Miller, Michelle Ruff and Spike Spencer.
- Bad Export for You: The American Special Edition includes the OST on a USB stick, but it only includes ten tracks and comes with clumsily-implemented DRM that effectively only allows it to be run on a Windows PC and can corrupt some school or business networks. At least it looks cool.
- Dueling Works:
- Loosely with Final Fantasy XV; Xenoblade Chronicles X supporters claim Monolith Soft is stepping in the right direction by enhancing and/or fixing elements from the previous installment, all the while attracting newcomers to the Eastern RPG genre, whereas Final Fantasy XV is alienating its own fanbase and changing its formula too much. Regardless of the reasons, Fandom Rivalry between Final Fantasy and Xenoblade (including its predecessors) are inherent.
- A looser one with Fallout 4, due to being a Eastern & Western Wide Open Sandbox released around the same time and being sequels to critically acclaimed titles, and being mutually exclusive releases (Fallout releasing on the PC, PS4, and Xbox One, while Xenoblade is exclusive to the Wii U).
- Cowboy BeBop at His Computer: Several sites, such as Siliconera and Dualshockers reported Lynlee's age had been changed to 15 for the western release. This is factually incorrect, since Elma plainly says she's still 13 years old during her introductory scene in the English version (@7:14-8:01).
- Fake Brit: Celica has a British accent in the English dub, but is voiced by American voice actress Mela Lee. Averted with the Classic Avatar voice choices.
- Fan Nickname:
- Elmo, Invader Elma, EL-MOS, Ayylma for Elma.
- "Momonado" for Lynlee, due to her resemblance to MOMO and having a hairclip shaped like the Monado. "Downs-chan" or "Potato" is also a common nickname for Lynlee as well, often used by people who bash the game's faces.
- Space Dunban, Gunban, Jinban, Shittan, or Sad Dad for Lao.
- Space Mumkhar for Douglas.
- Tony the Tiger for Ga Jiarg.
- Ru/L is known as "Space Goat".
- Alvin and the Ma-Non, for their high, squeaky voices.
- He's Bayonetta (alternately, Hideo) for H.B.
- What Could Have Been: The game was originally going to have a fixed main character but was changed halfway through development due to the addition of online play. Concept art of the original protagonist resembles Yelv.
