Goof: Twice they miscolor voltron's right leg yellow. So they both appear as being yellow, when the rest of the time they're the proper coloring.
Goof: At least twice Keith gives orders to red lion, but mistakenly says Hunk, when Lance is the pilot of red lion.
The episode of King of Beasts GoLion used to create this episode of Voltron is titled "The Planet Jarre Oath". Scenes of Prince Imperial Sincline (Prince Lotor in Voltron.) killing Planet Jarre's (Planet Yadle in Voltron.) citizens were removed for Voltron. Scenes of Glara soldiers beating Jarre citizens were also removed. Also Honerva (Haggar in Voltron.) used her occult science to create the double of GoLion. She did not steal blue prints to him.
