Lord X's original losing icon is also lifted from the remake, and his old left pose is the same pose Sonic.exe takes when he murders Tails in the adaptation. Specifically, this iteration of Lord X actually comes from Sonic (PC PORT) Remake. The Sonic in "Execution" and "Cycles" may appear to be just a slightly different rendition of Sonic.exe, but the cross-shaped scar on its torso gives away its identity as that of Lord X, the supposed true antagonist of the equally MST-ed sequel to the original story, Sonic.exe: Round 2.The vanilla game's "3, 2, 1, GO!" starting sign plays just before the beat drop in "Endless".Part of "Endless" has Boyfriend sing a few bars off of "Entry of the Gladiators", which was itself sampled by Carnival Night Zone in Sonic 3 & Knuckles, a level notorious for the "Barrel of Doom" that would leave you stuck in Carnival Night, well, forever (until the timer ran out, at least) if you didn't figure out what to do.Both the backing track and Majin's voice are composed from the iconic soundfont of the Sega Genesis to add another nod to the game he's from.
Xenophanes's segments reference multiple songs from the games and the mod itself, primarily the Drowning theme, "You Can't Run", and "Endless".
