Mobile Suit Gundam

Mobile Suit Gundam is a long-running franchise created by Sunrise Inc and Yoshiyuki Tomino, with multiple series playing some type of role in The Knights of the Multiverse. The ones focused on the most are Zeta Gundam by proxy of its New Translation film trilogy, ZZ, and the Char's Counterattack movie

Series Featured
While Zeta, ZZ, and Char's Counterattack are the three most prominent sources of Gundam media that're featured in KotM, with their storylines and characters being used. However, there are plenty of mobile suits (mechs), vehicles and other machines from the franchise are seen throughout KotM, mostly in season 1 (in terms of KotM itself, their appearances can boil down to cosmic coincidence). Said elements come from the following shows:

Gundam SEED, SEED X Astray & SEED Destiny
Though the Cosmic Era side of the Gundam universe is never represented in full in KotM, several elements from it are used in the series, like several characters, several mechs/mobile suits, and several references to certain events in the original media: * (This is even more meta because Athrun and Shinn's dynamic was somewhat based off of Kamille's dynamic with Quattro Bajeena in Zeta)
 * Mechs/Mobile Suits & Weapons
 * Strike Dagger
 * M1 Astray
 * Gells-Ghe
 * Providence Gundam
 * Hyperion Gundam
 * Duel Gundam
 * Buster Gundam
 * Forbidden Vortex
 * Raider Full Spec
 * Dreadnought Gundam
 * Chaos Gundam
 * Abyss Gundam
 * Gaia Gundam
 * Destroy Gundam
 * Legend Gundam
 * Akatuski Gundam
 * Stargazer Gundam
 * Strike Freedom Gundam
 * Kamille, Noriko, & Kazumi & Asuka's little squad that forms in the second season is based off of the core cast from the show, Shinn Asuka, Athrun Zala, Lunamaria Hawke, & Rey Za Burrel, with Asuka in place of Shinn (the emotionally scarred rookie that has a lot of anger issues that need to be resolved), Kamille for Athrun (the experienced soldier taking up arms once more)*, Noriko for Luna (the cheery, sociable pilot that has a tendency of goofing up), and Kazumi for Rey (the calm, rational one).
 * To angle into that more, Noriko and Atros form a sisterly bond that can be seen as a parallel to Lunamaria and her own little sister, Meyrin,
