A retrospective of Sonic Adventure 2 made formulate a theory

I don't know if this has been posted previously (trust me, I searched an entire day before writting this), but before I show this theory I have to give credit to Ruby of Blue's retrospective of Sonic Adventure 2's history because he is the one who came up with the concept of this theory.

Now to the theory, in the video Ruby of Blue shows a clip of the final boss (The Final Hazard), in wich Shadow says:"Gasp Sonic... You must be, the Ultimate Lifeform!" And Ruby proceeds to especulate, Gerald Robotnik at some point before the existence of Sonic, did go both to Angel Island and Mystic Ruins, but what did he see at Angel Island? A prophetic mural depicting Super (or Hyper) Sonic fighting against Eggman, that's why Shadow's quills look just like Super Sonic's, and when he explored the Mystic Ruins had to see the Echidna ruins alongside the Pefect Chaos mural, wich also explains why the core of the ARK began to look more and more like them and why there are artificial Chaos's in there aswell.

In other words Gerald Robotnik was amazed at the mural inside Hidden Palace Zone that he decided that from it 'Project Shadow' would be based from, trying to replicate the warrior that the mural depicted, thus why Shadow could be somewhat of a prodigy of chaos energy manipulation.

Now let's see Sonic's history with chaos energy through the games, in Sonic 1: Sonic manipulates the Chaos Emeralds to bring life to all of South Island, in Sonic 2: he finds the seventh Chaos Emerald allowing him to transform into Super Sonic, in Sonic 3 & Knuckles: He managed to defeat a giant Death Egg Robot that is being powered by the Master Emerald (even if Hyper Sonic isn't canon the fact that the transformation apeared in an official Sonic game, grants us with the information that Sonic officially is capable of enhancing the power of the Chaos Emeralds with the help of the Master Emerald), thus fulfilling the prophecy of the mural.

Even so during the Final Hazard fight in Adventure 2, Sonic notices that during the fight Shadow is becoming increasingly more tired, even advising Shadow that he should return to the ARK because his Super Form will destroy his body (proving more that the Echidna tribe Knuckles comes from, predicted that Sonic of all people will be the Ultimate Chaos Energy user), but allas Shadow ended up falling to Earth/Mobius because his body was not able to handle the Super Form anymore.

Now let's compare Sonic's and Shadow's feats that required the use of the Chaos Emeralds, Sonic alone or with help has defeated:

·Perfect Chaos: God of Destruction in the believings of the Echidna tribe (the same tribe that predicted the existence of Sonic).

·The Final Hazard: the Prototype of the Ultimate Lifeform of Gerald Robotnik originally the guardian of the Emerald shrine aboard the core of the ARK this monstrosity used Chaos Control and merged with the ARK to keep the trayectory of the ARK to crash on Earth/Mobius, Sonic and Shadow had to team up to kill the Final Hazard and use Chaos Control to transport the ARK back on Earth's orbit.

·Metal Overlord: the most powerfull form the original Metal Sonic has ever aquired (even Eggman admitted that with the power of the Chaos Emeralds it would be near impossible to defeat Metal Overlord).

·Perfect Dark Gaia: an deity fated to destroy the entirety of Earth/Mobius every couple of milleniums so that it would be reformed again by Light Gaia (Chip).

·Dark Mother Wisp: a corrupted version of the creator of the race of the wisps aswell as the creator of the planets seen in Sonic:Colors DS.

·Solaris: the Sun God of Soleana is a deity capable of ending the dimension it originates by consuming the time of the universe until a new one starts, this deity is only able to be defeated if it's killed in the Past, the Present and the Future.

·Egg Wizard: the most powerfull creation of Eggman to date, this machine was created with the help of Eggman Nega (the version of Eggman from Blaze's dimension), the power of this machine was so it could destroy both Sonic's and Blaze's worlds without any problem but if neither of the Eggmen wanted to destroy those worlds, they could instead merge them and create a new world where the Eggmen will be godlike with the capacity of changing that new world as much as they wanted since that new world was of their property, it is known that the full power of the Egg Wizard is currently unknown, but is known that the combined power of both the Chaos Emeralds and the Sol Emeralds (Blaze's dimension version of the Chaos Emeralds) were nothing to the power of the machine, it is theorized that the Egg Wizard is more powerful than Solaris: the Sun God of Soleana because the Egg Wizard could just make it so that Solaris doesn't exist in any possible timeline, the only way this machine was defeated was by Plot Induced Stupidity.

Shadow alone or with help has defeated:

·The Final Hazard: the Prototype of the Ultimate Lifeform of Gerald Robotnik originally the guardian of the Emerald shrine aboard the core of the ARK this monstrosity used Chaos Control and merged with the ARK to keep the trayectory of the ARK to crash on Earth/Mobius, Shadow and Sonic had to team up to kill the Final Hazard and use Chaos Control to transport the ARK back on Earth's orbit.

·Black Doom: leader of an Alien race known as the Black Arms (this species is also the reason Shadow has his distinct fur colors), after using the Chaos Emeralds and teleporting the Black Comet to Earth/Mobius's atmosphere and unleashing the wrath of the Black Arms on Humanity, Shadow used the Chaos Emeralds to transform into Super Shadow to defeat Doom, after Shadow ended his fight with Black Doom, he lifted the whole Black Comet so it burns with the atmosphere of Earth/Mobius, doing so he put an end to the threat of the Black Arms.

·Solaris: the Sun God of Soleana is a deity capable of ending the dimension it originates by consuming the time of the universe until a new one starts, this deity is only able to be defeated if it's killed in the Past, the Present and the Future.

Now that you have read the list of foes that were defeated by Super Sonic and Super Shadow respectively, I ask you a question: who really is the Ultimate Lifeform? From what the evidence sugest Shadow was created using a prophecy of Sonic as a template, that means that Gerald Robotnik based his Ultimate Lifeform from another Ultimate Lifeform.
