Continuity mistake: Optimus Prime, whose primary color is red, when being tied to a rock alongside his troops during the episode's climax, turns blue for a second.
Continuity mistake: After the Decepticons dig up Skyfire they look at his memory banks to show what happened to him. In the flashback it shows Starscream transforming into his Earth jet mode which he shouldn't have had because it takes place before they all crashed on Earth.
Continuity mistake: Skyfire's Decepticon symbol changes color throughout the episode. Sometimes it is purple and sometimes it is red.
Continuity mistake: At the beginning when Soundwave is attacking the bunker as he ejects his cassettes he says Buzzsaw (the gold condor) but instead ejects Laserbeak (the red condor).
Continuity mistake: Red Alert's door abbreviation has always been an F, then a shield, then a D, but when he is racing through the city when the Autobots are looking for him, he passes them and the abbreviation is: E, shield, D.
Continuity mistake: When the Quintessons have Daniel he appears to be strapped to an examining table but the strap changes in between shots. Sometimes it is on his chest but it later moves down to his stomach area and up to his chest again. Another scene shows his legs being strapped down as well but the strap seems to disappear.
Suggested correction: They only show Daniel strapped in once, and that's when he sits up & breaks them. All the other scenes they just show his face up close and you can't actually see that he's strapped down.
Continuity mistake: When we see Daniel in bed sleeping he is in his pajamas but when he is kidnapped by the Quintessons he is in his regular clothes.
