Akhlut the Orca

Akhlut was the Grandmaster of the Northern Tundra Dark Egg Legion and adversary of the Arctic Freedom Fighters, as well as the Walrus Herd. In 3237, he and his chapter attempted to take take control of the Walrus Herd's minds, but were stopped by the combined efforts of Sonic the Hedgehog, Rotor Walrus, Silver the Hedgehog, and the Arctic Freedom Fighters.

Battle for the Walrus Herd
During the Second Robotnik War, Akhlut and the rest of the Northern Tundra DEL managed to brainwash the Walrus Herd using a Psionic Emitter, which was placed in a Totem Base that had both surface and underwater sections. When Sonic and the Arctic Freedom Fighters arrived at the base to free the herd, Augustus, Flip, and Sealia all went underwater to destroy that section of the base. But Akhlut and several other Orcas immediately attacked them, Akhlut using his psychic powers to attack all three's minds, then using a focused psychic blast to send Augustus flying all the way back up to the surface.

During this fight, Akhlut explained how the struggle between the Orcas and Walruses for control of the Northern Tundra was "as old as the tides", and how the Orcas had helped both Dr. Robotnik and Dr. Eggman in the past by using their sonar to confuse the Walruses, leaving them prone to mind control. Akhlut also proudly boasted that with the Northern Tundra under Eggman's control, he could rule the Northern Seas and the herd would remain the Orcas' slaves forever.

However, Akhlut's plans were stopped when Rotor and Silver broke into the Totem Base, and Silver used a psionic neural interface to permanently free the Walruses from the Orcas' control. This also generated a psychic wave that hit Akhlut and the rest of the Legion, causing them to flee in confusion while bumping into each other.

Personality
Akhlut is ruthless and power-hungry, wanting to conquer the Northern Tundra by any means necessary-including using mind control to force the Walrus Herd into becoming his pawns. Akhlut also takes great pride in his powers and plans, explaining both in great detail to his enemies.

Abilities
Presumably--like other Orcas--Akhlut has a sonar, which can be used to "confuse" other creatures such as the Walruses, making them easy to control. Possibly a power given to him by his cybernetics, Akhlut also demonstrated the ability to combine sonar and psychic energies. This allows him to create "psychic explosions" of sorts that can cause great pain to his foes' minds. He can also focus the explosions into psychic blasts that are capable of knocking others back a far distance away.

Background Information
