Wolverine and the X-Men Season 1 Episode 6

Cargo ships have a booming side business - ferrying desperate refugee mutants to the island of Genosha. But when Nightcrawler realizes the refugees are mistreated, he secretly boards one ship and teaches the captain and crew a lesson. It seems like he has the situation under control until the ship is boarded by pirates. These modern-day marauders have made a practice of scuttling ships and abducting the mutants onboard. It's up to Nightcrawler to defeat the pirates and save the refugees in a battle on the high seas.
