1x33 - Marvel Disk Wars: The Avengers

Thor agrees to fight the Avengers when Red Skull threatens to use Hikaru to do the job in his place. Tony plans to pretend to fight Thor until they can come up with a more effective counterattack, but Thor will not play along. The fighting becomes more intense as Thor states he cannot let Hikaru kill anyone. Realizing that Thor will continue to protect Hikaru at all costs, the other Avengers vow to protect their young partners as well. The kids look on in horror as the fighting only gets worse. The fight proceeds to wreck the base, scaring the HYDRA agents, who learn from Skull that they and the base are no longer needed.
