Meanwhile, a vengeful [[Doctor Eggman|Dr. Eggman]] has taken new measures to defeat his arch-nemesis by enhancing his past creations and mechs.<ref name="StH4Story">{{Cite web|url=http://www.sonicthehedgehog4.com:80/us/html/ep1-story.html|title=Sonic the Hedgehog 4 :: Episode I|publisher=[[Sega]]|work=Story|accessdate=27 October 2017|archiveurl=http://web.archive.org/web/20130512061439/http://www.sonicthehedgehog4.com:80/us/html/ep1-story.html|archivedate=12 May 2013}}</ref> Despite Dr. Eggman's best efforts however, Sonic destroys each of his refined creations and chases the madman to [[Splash Hill Zone|Splash Hill]], where Eggman makes his departure into space. Using a [[Tails' rocket|rocket]] provided by Tails though, Sonic chases Eggman to his newest space station, the [[E.G.G. Station Zone|E.G.G. Station]]. There, Sonic defeats each of the creations and traps that Eggman reuses against him, including a powered-up [[Death Egg Robot]]. At the end, after defeating the Death Egg Robot, Sonic triggers a chain reaction that destroys the E.G.G. Station. Making it safely back to his planet, Sonic celebrates his victory in Splash Hill with his [[Animals|Animal]] friends. From there, the ending of the game will depend on the player's progress: <gallery type="slideshow" position="right" widths="225"> Sonic 4 Episode I bad ending.png|The bad ending of ''Sonic the Hedgehog 4: Episode I''. S4E1 MetalTeaser.jpg|The silhouette of [[Metal Sonic]] in the good ending. </gallery> *If the player has not managed to collect the seven [[Chaos Emerald]]s, Sonic will be posing to the player in Splash Hill. After the credits, Eggman will then be shown in the [[Egg Mobile]] laughing at the player, as the text "TRY AGAIN" appears below him. *If the player has managed to collect all seven Chaos Emeralds and also collects all of the Rings during the Splash Hill Zone sequence (by timing jumps perfectly as Sonic automatically runs) Sonic will use the Emeralds to turn into [[Super Sonic]] and pose to the player. If any of the rings are missed, the standard pre-credits pose without Super Sonic occurs. Regardless of which pose was triggered, after the credits, Sonic will then be making his classic pose before running to the right. Afterward, Eggman will appear in the Egg Mobile, laughing at the player before leaving the screen as well. Following that, a silhouette of [[Metal Sonic]] will be shown. {{Endspoiler}} ===Characters=== ====Main==== {|class="wikitable" style="text-align:center" !Image !Character !Biography |- |[[File:Sonic-Character-4.png|150px]] |[[Sonic the Hedgehog]] |''Our legendary hero returns!
