The Buried Castle

In this installment, Lotor travels to another planet and decides to capture a grieving female Medusan called Anga. She spends some time in the Arena on Doom and the royals are pleased by what they see: when Anga gets angry, she gets tough (just like the story of Medusa, her hair becomes serpants and her glance turns things to stone). Lotor and the old witch think Anga would make a fine Robeast.
