Morgana

Morgana is Ursula's equally ambitious sister who plans to take control of Atlantica and be better known than her sister. To make her plight, she hired the Grand Duke of Owls to be her Dragon for the episode. Although she was frozen in a block of ice in the end, Bowser will end up defreezing her to make her one of his loyal villain mooks.

She is set to be part of Team Nefarious because of Ursula being a grand council member of the villain league, which had made Morgana to sworn horrid vengeance on the league and believes that Team Nefarious will promise justice.
