Namor hires Franklin and Murdock to sue the human race on his behalf. When this doesn't work, he gets himself arrested so he can have his day in court.

Namor returns to the sea out of respect for DD and to stop Krang from taking over Atlantis.
Sub-Mariner [Namor]; Lady Dorma; King Neptune (flashback); Warlord Krang
Namor returns to Atlantis to find that Warlord Krang has taken his throne. When he spurns the affections of Lady Dorma, she turns him in and he is arrested by Krang as a traitor. Realizing that the only thing that will allow him to regain his kingdom and his subjects is the Trident of Neptune, Namor escapes to go and recover it.
Namor heads into the Forbidden Deeps as he continues his quest for Neptune's Trident. Krang sends Seaweed Man to stop him. Meanwhile, back in Atlantis, the natives are beginning to get restless under Krang's iron rule.
Sub-Mariner [Namor]; Dorma; Vashti; Henry Pym [Giant-Man]; Janet Van Dyne [Wasp]
When earthquakes rock Atlantis, Namor heads to the surface to find out what is causing the mayhem. What he finds is a giant drill being utilized by Hank Pym as he searches for clues to the origins of life on Earth.
Namor battles the Behemoth with the fate of Atlantis hanging in the balance. Krang has Puppet Master build a puppet of the Behemoth so he can control the creature mentally. Even under Krang's control, Namor is able to beat the monster. Krang snatches victory from defeat, however, when he shows up in Atlantis and informs the Lady Dorma that he will use the puppet to bring the Behemoth back unless she agrees to marry him.
Namor has lost his memory and the Leader of the Secret Empire convinces him to track down and kill the Hulk. As Namor rushes around New York looking for the jade giant, he is zapped by a ray from Krang which only succeeds in restoring his memory.
