1st appearance "Orka"
Returning to his undersea realm, Namor comes across a large herd of killer whales, led by the monstrous Orka, and takes him on. Namor is defeated by Orka, but follows him and discovers that Dr. Dorcas and Krang are actually behind Orka's powers, and are planning an attack on Atlantis. Namor gains the upper hand by threatening Krang's life which prompts Orka to turn against Dorcas. However, Namor's plan comes undone and he's taken down hard by Orka. Following Krang's orders, Orka puts a stun-collar and chains on the Sub-Mariner. Krang then announces an intention of marching into Atlantis with an enslaved Namor
