Several things
First this was rather well done, although ill admit it does have a DBZ thing to it, but mainly i would like to make a few corrections to the previous person.
First, the 'Hyper Sonic' from Sonic X, was Nazo, Nazo is a real character that never appeared in the series, just in the beggining credits, second, Shadic was the Shadow Sonic fusion, using Chaos fusion that only super shadow & Hyper sonic can use, because Shadow is just so much better, the Ultimate life form thing gave me a clue, as it should for everyone else
But saying which, i will admit that Sonic prefers to run around quick enough to obliterate the fabric of time, but you know
Basically it was very good, Britain is still loving Sonic parodies, brilliant old man.
