-Galvatron was sealed in ice in the Headmasters episode "The Emperor of Destruction Vanishes on an Iceberg" (his plans for Grand Galvatron were also revealed in that episode). He'll eventually be permanently freed from the iceberg in the Return of Convoy story pages.
-By 2021, Unicron's head has been moved to the Triple Z Point, where it is located in the Beast Wars Neo cartoon (as seen in the episode "Fight! Maximals"). This is in agreement with the previous TakaraTomy timeline that established Unicron's head being sealed there in 2010.
-Unicron is depicted as still having the eyes of Metroplex and Trypticon that were given to him in "Ghost in the Machine".
-Prime Breakdown (or in Japanese parlance, War Breakdown) was killed in the Prime episode "Crossfire". His corpse was repurposed as a new cyborg body for Silas in "The Human Factor" before being turned into a new type of Terrorcon zombie in "Thirst" (which did not air in Japan), in which Silas/Breakdown was finally killed. The absence of Silas from Breakdown's bio indicates that Silas has not remained alive to also be summoned by Unicron.
-Armada/Micron Densetsu Thrust was abandoned to die (for being a traitor) in the Armada episode "Union".
-Unicron only restores Starscream's body halfway, citing his betrayal in the episode "Ghost in the Machine" as the reason for his distrust.
-Unicron's desire to turn Cybertron into his new body likewise originates from "Ghost in the Machine", but he'll eventually achieve that goal (albeit momentarily) in the Beast Wars Neo episode "The Final Battle".
-Previously, Cybertron in the Japanese cartoon continuity was indicated to not have been restored until after 2036 in the G-2 story pages, something affirmed in the cartoon timeline included with Kiss Players, which Hayato Sakamoto contributed to. Unite Warriors now appears to be retconning Cybertron to already have been rebuilt by 2021.
