Triton beats Attuma's forces in episode 11 after learning about the attack on Pacifica from the mysterious Lady Dorma who Johnny brought back to headquarters.
[['11', 'SUMMARY', 'Johnny finds a mysterious lady named Lady Dorma and takes her back to the Headquarters. She claims to have come from a land beneath the sea called Pacifica, which is under siege by Attuma. They manage to slip past Attuma’s forces. Pacifica is losing hope and Attuma has shadowed the seabed. Triton can only fight man-to-man with Attuma while his men prepare traps to weaken Triton into a losing battle. The Fantastic 4 thwart every trap. Triton beats Attuma and the forces retreat. NOTE: Due to the rights to the Sub-Mariner being held by Grantray-Lawrence Animation, the adaptation of the first meeting between the FF and Namor was altered. Instead, Prince Triton, an original pastiche of Namor was reworked into the Namor role.']]
