Another major factor that causes a rift between Attuma and Namor is a woman — Lady Dorma to be exact (via Sportskeeda). Dorma is a member of royalty in Atlantis and has a relationship with Namor. On paper, the two seem like a great match, as they both want their kingdoms to prosper. However, trouble in paradise causes the couple to have many bumpy moments during their relationship. At one point, Lady Dorma promises herself to a warlord named Krang when Namor has gone missing from Atlantis. However, upon his return, Lady Dorma reunites with Namor, and all is right in the world. That is, until he develops feelings for Sue Storm from the Fantastic Four — aka The Invisible Woman. But more on that later.
Once Attuma wages war on the kingdom of Atlantis, he has hopes of making Lady Dorma his queen. Unfortunately for him, she wants nothing to do with him, arguing that she only has eyes for Namor. As you might imagine, this doesn't make Attuma feel good, as he already sees Namor as his rival. And now, Namor has become his romantic rival as well.
According to Marvel, the downfall of Attuma's war against Atlantis is due, in part, to Lady Dorma. In order to stop Attuma and his warriors from conquering her home and defeating Namor, she turns to the Fantastic Four for help. Though she sees Sue as her enemy, she wants to save Atlantis from Attuma more.
