 is an American animated television series created by TBD. It is being produced by Cartoon Network Studios and aired on Cartoon Network from July 5th, 2002 til August 18th, 2006.

Synopsis
An octopus starts his journey on being the ruler of the oceans by planning to take over the whole ocean region he lives in and turn it into his empire, but it proves to be much more difficult, even with hilarious hijinks ensuing in the process and a shark wanting to stop him in the process.

Main

 * Theodore "Theo" (voiced by Keith David) - A power-hungry and intelligent common octopus who wants to become the emperor of the ocean region, but always fails massively.

Supporting

 * Ocean (voiced by Alanna Ubach) - a loyal, yet sweet and dumb teenage mermaid who is Theo's assistant, who despite her stupidity, is very loyal to him.
 * Mario von Shrimp (voiced by TBD) - a skilled chef shrimp with an Italian accent, often cooking food to feed Theo and Ocean.
 * Ma (voiced by TBD) - a snarky octopus who is Theo's mom as she loves to complain about everything, especially her son.
 * Metalscale (voiced by TBD) - a fish-shaped aquatic mech that is controlled by a goldfish, being very royal to Theo and even taking him on rides.
 * Oka (voiced by TBD) - an insane orca who is part of an Orca cult and sees Theo as a God for some reason, being very loyal to him.

Antagonists

 * Fang (voiced by TBD) - a focused and heroic, yet clumsy shark who is set to sabotage Theo's plans on invading the ocean, being his arch-nemesis. However, his clumsiness causes Theo to always win.
 * Squiddus (voiced by Kevin Michael Richardson) - a power-hungry squid who, like Theo, wants to take over the world, but upon finding out Theo is planning to do it as well, he tends to make sure he doesn't succeed, making him Theo's rival.
 * Hector von Shrimp (voiced by TBD) - a loyal, but snarky shrimp who is Mario's younger brother, but unlike him, is not into cooking. He is very loyal to his leader Squiddus and does anything he says, but does find him as an annoyance at times.
 * Harry (voiced by TBD) - a flamboyant hermit crab who claims to be the king of the bandits, being obsessed with shiny trinkets and always gets in Theo's way, being considered as his annoyance.
