What cartoon clips are on deck this Saturday morning? Shapeshifters and identity theft are definitely the theme of this week's batch of cartoons — Skrulls invade the Avengers, and a bear tries to assume Finn's identity on Adventure Time. Also, the Iacon City relic saga continues on Transformers:Prime, as well as the pro-bending championships arc on Legend of Korra. Minor spoilers ahead!
The Avengers: Earth's Mightiest Heroes – "Who Do You Trust?"
Nick Fury believes Skrulls — one of the three major alien races in the Marvel Universe, I want to to officially add the Shi'ar — have used their shape-changing abilities to replace one of the avengers with a spy. I hope the Skrull spy is Captain America, but this clip leads us in another direction.
Thundercats – "Birth of the Blades"
Thundercats in space! Mumm-Ra (doing a really great Darkseid impersonation) seeks to destroy a star in the name of intergalactic conquest in this clip. This episode sheds light on the origin of the Sword of Omens and the role Mumm-Ra played in its creation.
Green Lantern: TAS – "Fight Club"
Chuck Palahniuk penned this week's episode of GL:TAS. No, I lie. Instead, the Green Lanterns and Red Lanterns are racing to search for code that opens the Maelstrom. The code is hidden on a prison asteroid, with a Thanagarian (like Hawkman!) prisoner the only one who knows the code.
Adventure Time – "In Your Footsteps"
I never believed we would have to worry about bears becoming identity thieves, but according to Jake and Finn, it could be a reality. Finn uses the Enchiridion, the hero's handbook, to save a bear while choking, but the bear begins to stalk the duo and mimic Finn.
DC Nation Shorts - New Teen Titans – "Blackfire's Babysitter"
Supervillain Blackfire needs a babysitter, so she calls on her estranged sister (and Teen Titan) Starfire at the last minute.
Young Justice: Invasion – "Alienated"
Kroloteans are invading Earth, but the Justice League joins Young Justice to fight off the threat. This clip features Blue Beetle as he chases down some Kroloteans.
The Legend of Korra – "And the Winner Is..."
The Fire Ferrets prepare for the pro-bending championship, but Amon announces his plan to shut down the sport forever. Korra is not happy. If you are not watching this show, you should be.
Ultimate Spider-Man – "Back in Black"
Harry Osborn needs rescuing, but Venom is back! Enjoy some quippy Peter Parker action as Spider-Man fights Venom in this clip.
Transformers Prime – "Triangulation"
Dreadwing and Optimus Prime face off like two wild west gunslingers in this clip. Dreadwing leads a team of Decepticons, while Prime is alone, giving the Decepticons the upper-hand in the hunt for the second Iacon City relic — a relic hidden in deep in Antarctica.
