First episode in which Battle Cat speaks.
The Evil Warrior's vehicle, the 'Doom-buster' is mentioned for the first time and will be referenced again in Double Edged Sword (1983), but not seen until The Shadow of Skeletor (1984).
The animation of He-Man kicking Skeletor's Freeze Ray device into the air is used again in Gateway to Trouble (1985) when he kicks one of the Evil Horde's Destructo Tanks.
The animation of Orko shortly before he and Cringer enter the Time Corridor is reused in Eternal Darkness (1983) after Man-At-Arms makes a compliment about Orko's hearing.
