Doctor Robotnik's Doomsday project is quite similar to ultimate annihilator that he used in the Archie comics.
When Snively gets into that escape pod, and when it comes up from the wreckage, the doors look like they slide open horizontally. [During the Doomsday wreckage scene, they do actually close horizontally.] However on the very final shot of the pod,a single door slides up vertically!
Sonic: Couple of tankbots. No probs, long as Antoine doesn't trip over anything.
Bunnie: Like his feet.
Antoine: What is being wrong with my feet?!
Bunnie: (covers Antoine's mouth) Put a sock in it, Antoine!
(Sonic catching Antoine)
Antoine: Are zee Angels?
Snively: Big round guy finally let Sonic defeat him. Well don't celebrate too soon, hedgehog! Now it's my turn, and I'm not alone! (Mysterious red-eyed being appears behind him)
Sonic: No more Robotnik - too bad!
Sonic: Way past cool - Robotnik's gone!
(When the base was about to explode)
Snively: But sir, wait for me.
Dr. Robotnik: Only room for one, Snively!
(Dr. Robotnik escapes in his ship)
Snively: You don't give me enough credit... Julien!
Snively: Uh, sir.
Dr. Robotnik: (yelling) Shut up, Snively!
Nicole: The possibility of danger does exist, Sally.
Robotnik: Let them explore. Maybe they'll find my little surprise.
Sonic: Now I know how a bug zapper feels.
Sonic: Now you're ticking me off!
Snively: (Muttering) Your incompetence wil ruin everything you ugly boil!
Dr. Robotnik: WHAT was that, Snively?!
Snively: You don't give me enough credit, Julian!
Snively: Sir, SIR! The hedgehog is back!
(As Antoine is sleeping at his post)
Sonic: Oh man, if brains had hair, he'd be a cueball.
Snively: So, the big "round" guy finally let sonic defeat him. Well, don't celebrate too soon hedgehog. It's my turn, and I'm not alone...!
Dr. Robotnik: I really hate that hedgehog. I hate him. I hate him! HATE HIM!!! Hate. Hate! Hate!! HATE!!!!! (Dr. Robotnik Screams, Sonic and Sally spirals out of control and lands on a cliff)
Sonic: All right! Way past cool! Robotnik's gone!
Robotnik: You have been a most worthy adversary, but in every game, there are winners and there are losers. And as you know, in this game, losers get roboticized!
Sonic: No more Robuttnik. Too bad.
Sally: What? Too bad?
Sonic: Hey, without a villain, what are heroes gonna do?
Sally: You'll always be my hero, Sonic Hedgehog.
Sally: If a high-five does that, what happens with a kiss? (puckers up)
Sonic: Whoa whoa whoa, I don't want to find out! Outta here!
Sally: OK, now remember, once we connect the stones.
Sonic: Whoa Sal! What's this "we" stuff?
Sally: Because I'm going with you.
Sonic: No way, Sal. You...
(Sally claps her hand over his mouth)
Sally: We are in this together, Sonic Hedgehog, however it ends. Check?
Sonic: (Kisses her hand) Check.
Snively: Sir, sir! They're inside the machine! Shall I alert the forces?
Robotnik: Oh no, no, no, Snively. Let them explore. Perhaps they'll find my little surprise.
Snively: (under his breath) Your stupidity will ruin everything, you ugly boil.
Robotnik: WHAT was that, Snively?!
Snively: I said the Doomsday Machine's going to need more oil, sir.
Ben Hurst would later find himself attached to another Sonic series, the largly neglectedSonic Underground.
Though the series was cancelled, the Archie comic that stemmed from the show continues to this day.
The series was cancelled after it fell in the ratings to arguably the most established show of the 90's: The Power Rangers.
The USA Network rerun cuts out the scene where Sonic plants bombs around the base of the Doomsday Machine, as well as a (crucial) part of his escape from the Roboticizer.
According to Hurst, the red eyes seen at the end of the series belong to: Ixis Nagus from "The Void".
