Ep 21. Koragg's Trial

Koragg takes his magic from Necrolai to challenge the Rangers' new Legend power. When Koragg grows, the Rangers use the Manticore Megazord and start to win, but Imperious summons a virus that infects the Megazord (and Rangers inside). Koragg, angered by Imperious' intrusion on their battle, negates the effects of the virus. As a result, Imperious makes Koragg stand trial for his countless failures and treason. Koragg argues that while he fights with honor in The Master's name, Imperious does not and shouldn't be trusted. In the end, The Master agrees and allows Koragg to keep his power.
