- While converting between games, one of the games LLENN tries gives her an alien avatar which looks suspiciously like a female Frieza.
- The leader of Team SHINC is named Eva, but her teammates call her Boss.
- The leader of Team ZEMAL dresses up similarly to John Rambo with the red headband, although he uses a M60E3 GPMG.
- When thinking of who to team up with for the second Squad Jam, Karen complains that "LLENN doesn't have many friends."
- In Squad Jam 2, the leaders of the 7 allied teams◊ are pretty clearly designed after the main cast of The Expendables and Universal Soldier.
- The names of Clarence and Shirley are a nod to Airplane! and Leslie Nielsen's famous line.
- When the dome battle begins in Volume 3, one of the tavern patrons watching the fight comments that the opposing teams shooting randomly into the brush staging a fake battle to bait out LLENN and Fuka reminds him of a certain movie about an invisible alien who hunts humans for sport.
- The designs of Team T-S◊ look a lot like Federation Marines from the Metroid Prime series.
- In Volume 3, when the last member of PM4 is throwing beds down the stairs to slow down MMTM, one of the spectators in the pub comments it's like an old video game where a gorilla throws barrels down platforms.
- M activating a plasma grenade and preparing to blow himself up along with Pitohui is reminiscent of Vasquez and Gorman, complete with her hand covering his on the grenade.
- The Mook Horror Show when Team MMTM gets slaughtered and seeing Pitohui make her entrance with a red Photon Sword is practically lifted right out of Rogue One.
- Pitohui's Photon Sword itself is red and double bladed, making it a reference to Darth Maul... at least for a moment.note
- After M & Pitohui commandeer one of MMTM's Humvees to chase after LLENN, she starts kicking M to drive faster and screaming "Hi-Yo, Silver!"
- Later, she's standing on the roof of the Humvee, in the Captain Morgan Pose with her sword pointing ahead, imitating the Warhammer 40,000 meme of "Drive me closer! I want to hit it with my sword!"
