Continuing the trend of "giant final boss monster that Super Sonic fights", Solaris was that unlucky candidate in the ill-fated Sonic the Hedgehog 2006. Solaris is actually the combination of two entities, Iblis and Mephiles, and is technically the most powerful character in the Sonic series(after Mighty & Cheese), as it took not one, not two, but THREE Super Duper Hedgehogs just to destroy him. Eventually, he was deus ex machina'd and erased out of existence, making one wonder what the point was. Solaris has a fire & sun theme and uses attacks as such(complete with the prequiste giant lasorz), and is capable of altering time and space itself. He's pretty much your standard, run of the mill 3D Sonic final boss, if not a bit more angelic. But hey, he's got some catchy boss music.
