Dark Oak (ダーク・オーク Dāku ōku?), formerly known as Lucas (ルクス Rukusu?, lit. "Luchs"), is a character from the Sonic X anime series and the main antagonist of the Metarex Saga. He is the powerful leader of the Metarex, a large army of bio-robots that scours the galaxy for the Planet Eggs.
Dark Oak has one large, green eye and carries a golden sword. His armor is composed of varied shades of purple, with a large green orb on his chest and two tattered halves of a black cape hanging from his shoulders.
As Lucas, he is known to have light grey skin and purple hair with two brown non-flowering buds, similar to what Cosmo has too. He has be seen to wear black clothing with one dark red button on the center.
Many years ago, Dark Oak was originally born Lucas, a male member of a plant-like species and at some point married Earthia. Eventually rising to the combat faction leader of Green Gate, Lucas and his forces entered a war with an unknown enemy when his planet was ensnared in the turmoil of war. As they were losing the battle, Earthia wanted to leave their planet behind and start a new life, retreating from their enemies. Being a warrior himself, Lucas would rather stay and fight to stop the enemy causing further destruction in the universe, which brought him into conflict with his wife. Eventually, Earthia told him if he did not like it he could stay and fight the enemy himself and Lucas agreed.
Following that, Lucas and the majority of males in his race stayed behind to fight. Despite the power they had obtained in their monster forms, however, Lucas and the others met the opposition with much failure. Later, Lucas stole his home world's Planet Egg and tried to harness its energy to attain his and his followers' monster forms for longer periods of time, when his actions was discovered by Earthia, who had discovered the plants were dying before leaving her planet. Horrified that her husband had sacrificed so much to fight, Earthia called Lucas a traitor for destroying his own world to fight the enemy and Lucas called Earthia a traitor for wanting to abandon the war entirely. Lucas then vowed to crystallize the life force of all planets to build an army to combat their enemy and Earthia and all the female members of the race left while Lucas and his fellow rebels remained behind to fight for their lost cause.
Even with the increased energy used to maintain their transformations, Lucas and his men still met with failure and suffered many casualties. Eventually Lucas came up with a plan to transform their bodies into that of techno-organic machines. Lucas and the survivors (four other males who would become his most trusted subordinates as Commanders of the Metarex) would now take new identities based off of various flora plus the color of their new bodies, with Lucas becoming Dark Oak. With a final act, however, Earthia ordered the remaining beasts killed along with the planet and unleashed a nuclear strike that devastated their world. Dark Oak and he and his rebels survived, however and vowed to fulfill the destiny of the universe by eliminating all life except plants and plant-based creatures. Under the leadership of Dark Oak, they eventually built robots and raised an army, referring to themselves as the Metarex.
Dark Oak first appeared to challenge Super Sonic in orbit around Sonic's planet in order to claim the Chaos Emeralds from him. Despite Super Sonic's powers, he was unable to defeat Dark Oak. Dark Oak taunted at Sonic that his defeat was certain but surprisingly, Sonic used Chaos Control to send the emeralds away before he fell down to his world. Dark Oak remarked that Sonic had simply delayed his triumph. Before Dark Oak departed for space, he alerted his forces to search for the Chaos Emeralds and to send a Metarex to remove the Planet Egg of Sonic's world.
Later, Dark Oak appears behind the scenes, scheming his enemies' downfall in secret. He dispatches Scarship, the space-faring Metarex, to destroy them. After this fails, Dark Oak confronts Sonic and co. in a battle over the seven Chaos Emeralds at one of his fortresses, but they soon find that he was simply contacting them with a hologram. After the fortress where he was keeping the last two Chaos Emeralds was destroyed and the jewels scattered, Dark Oak declares that it was only a test. From that point on, Dark Oak stays out of the limelight, dispatching his Metarex commanders in various attempts to kill Sonic and co. He also recruits Doctor Eggman as an ally, though Eggman later proves traitorous.
Dark Oak's plan to let plant life reign supreme was later revealed at galactic coordinates 0-0-0. At the end of a 1,000 year period, Dark Oak arrives in time for a time/space anomaly to open. Using the energy released from an alternate dimension, he begins to construct a massive plant which will aid in the Forestation process. Using the Planet Eggs as a source of water and the Chaos Emeralds as a source of light, the two things most essential to plant growth, Dark Oak combines with his last two commanders to form Final Mova. He then absorbed all the power of the Chaos Emeralds and supposedly grew even more powerful. Knuckles loaded the Master Emerald into the Sonic Power Cannon and killed two of the three heads that the beast had, but Dark Oak was still alive. Though Dark Oak made an attempt to suck the life out of everyone in order to make himself stronger, Cosmo was not affected. She was able to give the Chaos Emeralds to Sonic and Shadow, allowing them to assume their Super forms. They seemingly killed Dark Oak, but again he survived, albeit narrowly. Realizing that he was going to die, he created a massive gravity field (which even Super Sonic and Super Shadow couldn't break through), threatening to cause the Planet Egg to explode, destroying everything in the entire universe, intent on taking everyone down with him. Cosmo, in a self-sacrificing act, fused with Dark Oak and was able to immobilize Dark Oak with her power. Reluctantly Tails had no choice but to fire the Sonic Power Cannon with Super Sonic and Super Shadow in it and the combined power of the hedgehogs killed Dark Oak once and for all. Super Shadow then used Chaos Control himself removing himself and the Planet Egg from the vicinity and disappeared thus destroying Final Mova.
Following Dark Oak's destruction, Lucas was shown in a mysterious location, seemingly reformed and repentant. There, he was greeted by and departed with some form of Earthia.
Powers and abilities
Before becoming a Metarex, Lucas had the ability to transform into a colossal tyrannosaurus-like being with incredibly enhanced strength and durability. However, maintaining this transformation would drain Lucas of his own energy, and extended usage of it would kill him.
As a Metarex, Dark Oak was by far the most powerful of the Metarex Commanders and one of the most of the powerful characters in Sonic X, possessing a level of might so great that even Super Sonic was ultimately unable to defeat him. However, during their first fight, Super Sonic had toyed with him so much that he was too exhausted to fight back, and Dark Oak even admitted that he only had a slim chance of beating Super Sonic. Dark Oak had unimaginable physical strength, enough to bruise Super Sonic and repel his charges without recoil, and possessed as well super speed comparable to Super Sonic's. He likewise had vast physical durability, only receiving a small wound from Super Sonic's attacks. He was also capable of flight, allowing him to move freely through the void of space.
Besides his incredible power, Dark Oak was an intelligent schemer, able to lay out complex and successful plans of his own.
Dark Oak wielded a large green sword, suggesting he had some proficiency on swordsmanship. So far, he was only seen using it in his battle with Super Sonic, but with little usage.
