Summit Meeting Voltron: Defender of the Universe : Season 1 Episode 47

When Allura, Keith, and Coran call together the rulers of Pollux, Titus, Torus, Yadle, and another planet to plot extended defense against Zarkon, he makes an appeal to the Drule Empire which Doom is a distant part of for support. Without knowing he was rejected, he has Haggar set up a group of impostors as an ally's ambassador-crew and "attacks" them when they land on Arus. During the resulting scouting-mission, Keith invites Allura to use the Black Lion. But Lotor has rigged it to fail and, after a crash, she is forced to run from his last-chance interception and Keith is injured when defending her. Voltron is needed to defeat Haggar's attack, denying Keith any time to recover.
