She-Ra: Princess of Power: Season 1, Episode 6

1 - 6: The Sea Hawk

Adora runs into Sky Hawk, a pirate captain, who is trading goods with The Horde. After realising who she is, he orders his men to capture Adora and hand her to Catra and the Horde. While on her way back to port HQ, Catra is looking forward to her reward for capturing Adora, but the pirate captain has a change of heart and decides to go after Catra and save Adora. He saves her but dealing with Catra seems to be beyond his fighting capabilities. Lucky for him, rescued Adora turns into She-Ra and comes to the rescue.
