Synopsis[]

Sonic the Hedgehog Encyclo-speed-ia is a lore book that summarizes several major video game installments in the Sonic the Hedgehog series and its spin-offs, from the debut of the original Sonic the Hedgehog and up to 2021. The book features each major game in the order of which they were release, although some spin-off games are grouped into sections with themes dedicated specifically to them, including video games for the arcade, educational games, and video games for mobile devices. The entries for each game in the book generally includes some of the following sub-sections:

  • Release Dates: The release date for the video game within certain regions.
  • Overview: An introduction section summarizing noteworthy facts about the video game, its elements, and mechanics.

  • Items: An overview of the different noteworthy items that appear within their designated video game,
  • Enemies: A list of the enemies that appear in their designated video game. These listings include brief descriptions of their behavior, the locations in the game, and names for each enemy. Many of these lists provide as well English names for enemies that were never given an English name following their video game's release or were never given a name at all.
  • Bosses: A list of the bosses that appear in their designated video game. These listings include brief descriptions, factoids, appearances in the different levels, and names for each boss. Many of these lists provide as well English names for bosses that were never given an English name following their video game's release or were never given a name at all.
  • Factoid: Small information boxes that provide canonicity information, cut content, localisation differences and other minutia data for different aspects of their respective video games.

Goofs[]

In Sonic the Hedgehog Encyclo-speed-ia, there are a number of erroneous statements and misprints:

Chapter Page(s) Sub-section(s) Error
Sonic The Hedgehog (16-bit) 8 Factoid The section states that Sonic was supposed to be "part of the band". It is meant to say "part of a band".
9 Zones The description for Spring Yard Zone misspells the word "bridge" as "brdige".
12 Enemies The Orbinaut's description is identical to the Crabmeat's description: "It crawls over a small area, occasionally launching projectiles from its claws."
Sonic Arcade Classics 16 Overview The section mistakenly says "Players sit insidean arcade cabinet shaped like Sonic's patrol car". It is supposed to say "Players sit inside an arcade cabinet shaped like Sonic's patrol car".
Sonic The Hedgehog 2 (16-bit) 22 Overview The section incorrectly states that the Special Stage in Sonic the Hedgehog 2 can be accessed via the Star Post checkpoints with twenty Rings. In truth, the Ring requirement to access the Special Stages via Star Posts is fifty.
23 Zones Out of the four screenshots that are used to represent Emerald Hill Zone, the first is actually a screenshot of Green Hill Zone from the original Sonic the Hedgehog.
24 Zones Metropolis Zone's boss is referred to as "Flying Eggman II", despite the fact that no mech before this existed under the name "Flying Eggman".
25 Enemies The image of the Grabber's sprite is missing both its winch, and front set of legs.
27 New Faces The art used for the Micky Animal is actually a fan-made drawing by DeviantArt user RetroOwl.[5] Also, the description stating that this Animal debuted at Hidden Palace Zone in 2013 remaster of the game is false, as Micky can be found in Mystic Cave Zone.
Sonic CD 33 Enemies Pata-Bata is misspelled as "Bata-Bata".
34 Factoid The Factoid states "Wait too long, and Sonic will say, "I'm outer [sic] here!" He'll then jump off the stage, costing you a life." This is not true, as Sonic yelling "I'm outer here!" results in an instant Game Over. However, it did cost a life in early prototype builds for the game.
Sonic Chaos 36 Overview The section erroneously claims that to access one of the game's Special Stages, the player must reach the end of an Act while holding one hundred Rings. In the game, the player is automatically warped to a Special Stage upon collecting one hundred Rings. However, regardless of how the player leaves the Special Stage, the Act that they entered from will be ended and they will begin the next Act instead.
37 Zones The section's entry for Mecha Green Hill Zone states that Eggman has "completely converted the Green Hill Zone of Sonic the Hedgehog 2 (8-bit)." In actuality, the Zone in the latter game is called "Green Hills Zone".
Dr. Robotnik's Mean Bean Machine 41 Game Modes In the description for Scenario Mode, the name "Dr. Eggman" is incorrectly used instead of "Dr. Robotnik".
Sonic The Hedgehog 3 48 Story The entry states that Super Sonic defeated Dr. Eggman in Sonic the Hedgehog 2. While the player can obtain all seven Chaos Emeralds, they cannot use Super Sonic in the final Zone, as there are no Rings there to use to transform. Also, while Sonic does transform into Super Sonic in the game's Good Ending, that only happens after Eggman has already been defeated.
49 Zones The Angel Island Zone's profile erroneously states that "A carpet-bombing by the Flying Battery sets the second act ablaze". In truth, Angel Island Zone is set ablaze in Act 1 by a battalion of Fire Breaths.
53 N/A This section depicts screenshots from Green Hill Zone, Mushroom Hill Zone and Death Egg Zone, all of which belong to Sonic the Hedgehog and Sonic & Knuckles respectively, and which do not belong in the "Sonic The Hedgehog 3" chapter.
Sonic & Knuckles 55 Zones While the other Zones featured in this section shows at least one screenshot from each Act, Lava Reef Zone only displays two screenshots both from Lava Reef Zone Act 1. No images from Lava Reef Zone Act 2 are displayed.
Sonic The Hedgehog Triple Trouble 62 N/A Sunset Park Zone is mentioned to be a "sprawling railway". While it has elements of the railway theme, it is actually described to be an abandoned amusement park.
62-63 N/A In these sections, the Meta Junglira Zone is in every instance misspelled as "Meta Jungura Zone".
62 Special Stage The book states "You'll need to either navigate a maze and battle Fang before the time runs out or collect eighty Rings with the Tornado within a strict time limit." In the actual game, however, the player battles Fang after completing either variation of the Special Stage, not only the maze one.
62 Boss appearances in Zones Knuckles is incorrectly stated to be the boss of South Island, as opposed to Tidal Plant Zone.
Knuckles' Chaotix 69 Stages A screenshot used to depict Marina Madness has mistakenly been taken from Techno Tower.
72 N/A The image on the page depicting sprites of the Chaotix standing on top of 1-Up Item Boxes is a taken straight from a sprite sheet of the objects in Knuckles' Chaotix uploaded by The Spriters Resource users Doc Melonhead and Dolphman.[6]
73 Factoid The entry states "Enthusiastic fans also found that Amy Rose was supposed to appear in a scrapped Sound Test mode in other leaked versions." In truth, the Sound Test and Amy's appearance were not scrapped, and can still be accessed and viewed in the final game via a cheat code in the color test.
Tails Adventure 76 N/A The screenshot on the page that depicts the title screen for Tails Adventure is a rip of the title screen graphics by The Spriters Resource user, DogToon64.[7]
77 Stages The first screenshot used for the Volcanic Tunnel's profile shows the opening cutscene for Tails Adventure instead.
The first screenshot used for the Cavern Island's profile shows a screenshot of Volcanic Tunnel instead.
78 Bosses Despite both the "levels" and "boss appearances in Zones" portions of the Tails Adventure section listing the boss of Volcanic Tunnel as the Mecha Golem, and the boss of Cavern Island as the Mecha Golem (5-gou), their sprites are erroneously captioned with the other's name.
79 Enemies The Jumping Combatant is listed twice in Enemy section. The second entry names them "Jumping Soldiers" and says that they appear in Polly Mt. 2 when they actually appear in Polly Mt. 1. Their first entry also states that they appear in Lake Rocky despite not appearing there at all.
The Robo Kukku is erroneously stated to be found in Battle Fortress 1. In truth, they are exclusive to Battle Fortress 2.
Sonic 3D Blast 88 Enemies The sprite for the Snake Badnik is erroneously captioned as "Caterkiller" and has several of its segments miscolored and misplaced.
Sonic Adventure 98 Stages The description for Twinkle Circuit claims that this Action Stage must be completed before Sonic can access Twinkle Park. In reality, Twinkle Circuit is an optional Action Stage for Sonic.
The description for Final Egg erroneously states Birdie's family members to be his parents, rather than his siblings.
Sonic Shuffle 108 Forcejewels The description for the 1 Force March Forcejewel is erroneously also used as the description for the 6 Force March Forcejewel.
Sonic Adventure 2 / Sonic Adventure 2: Battle 115 Chao The book states that toys can be purchased from the Black Market, while in the actual game, they can only be won from Chao Races.
118 Factoid The entry states that only Dr. Eggman, Amy and Maria's menu themes for Sonic Adventure 2 were released in Japan. While this claim is correct in both Amy and Maria's cases, Eggman's theme was also released in western territories. Shadow, Omochao, and the Secretary's themes (which were Japanese-exclusive) are not mentioned.
Sonic Advance 120 N/A The screenshot on the page that depicts the title screen for Sonic Advance depicts a volume bar in the top-left corner.
121 Zones The second screenshot for Egg Rocket Zone incorrectly depicts Cosmic Angel Zone instead.
122 Enemies The GamiGami's name is misspelled as "GaniGani". However, the name is spelled correctly on the following page.
Sonic Advance 2 124 Overview The book states "Unique to this outing, all of the bosses are fought on the run." This is untrue, however, as the Super Eggrobo Z remains entirely stationary during its boss fight in the game.
125 Zones Ice Paradise's section is erroneously accompanied by two screenshots of Ice Mountain Zone from Sonic Advance.
128 Enemies Madillo's sprite is incorrectly cropped, having loose pixels from another sprite on the right of said sprite.
Sonic Heroes 131 Story In the "Team Rose" section, despite Chao being genderless, Chocola is referred to as Cheese's brother. This is consistent with the game, though.
Stages Sea Gate is erroneously accompanied by two screenshots of a fan-made, modded version of the stage for Sonic the Hedgehog (2006).[8] The first screenshot correctly shows the stage with Team Rose, while the other two only have Amy, with the third showing an Egg Gunner attacking her.
138 Bosses In Metal Madness' section, it states: "His glowing weak points change color, showing which skill type he's currently immune to." The "immune to." fragment is accidentally also added to the end of the Metal Overlord's description, leaving a broken sentence.
Sonic Battle 140 Story It is erroneously stated that Emerl was found by Tails, while in Sonic Battle, Emerl is found by Sonic and brought to Tails.
142 Multiplayer In the descriptions for Soniclash! and Tails' Fly & Get, it is stated that four Game Paks are needed to play them. In truth, they only need one Game Pak.
143 The mini-game, Shadow's Speed Demon, is erroneously called "Sea Gate".
Shadow The Hedgehog 157 New Faces It is mentioned in Black Doom's section that he uses the Chaos Emeralds to transform into Devil Doom. In Shadow the Hedgehog, Black Doom teleported away to prevent Shadow from attacking him and left the Chaos Emeralds behind before then transforming into Devil Doom.
Sonic the Hedgehog (2006) 163 Stages In the description for New City, Radical Train is misspelled as "Radial Train".
Sonic Riders 169 Courses Space Theater is erroneously called simply "Theater".
171 New Faces In this section, the E-10000 series is mistakenly referred to as the "E-1000" series. In turn, E-10000R and E-10000G are referred to as "E-1000R" and "E-1000G", respectively.
Sonic and the Secret Rings 183 New Faces King Shahryar's entry states "He mistakes Sonic for the Ma Djinn forces of Erazor." In Sonic and the Secret Rings, this never happens (not even in an implicit manner), with Shahryar merely finding Sonic insolent.
Sonic Rush Adventure 185 Stages Blizzard Peaks is incorrectly called "Blizzard Peak".
187 Enemies The Crystal Head, Kaizoku Glider and Kaizoku Snowball, who all appear in Blizzard Peaks, are erroneously stated to appear in Haunted Ship.
189 New Faces In Captain Whisker's section, Mini is incorrectly referred to as "Min".
Sonic Chronicles: The Dark Brotherhood 207 Chapters The synopsis of the plot for Chapter 1 states that Tails arrived in Green Hill Zone to inform Sonic of Knuckles' kidnapping. In the game, Sonic is the one who arrives in Green Hill while Tails contacts Sonic via radio from Central City.
209 Playable Characters Omega's entry states, "you must recover his dismembered pieces and reassemble him so he may join your party." In the game, the player finds Omega destroyed by the Nocturnus Clan in a location of Metropolis, but the player does not have to look for multiple pieces for Tails to reassemble him.
Sonic Unleashed 196 Release Dates (PS3/X360) The Japanese release date is listed as "February 19, 2008" instead of 2009.
Sonic and the Black Knight 212 Stages The Cauldron's description is missing a space between the words "an" and "abandoned".
213 Factoid The entry states that Sir Lancelot comments on the similarity of the Red Dragon with the Biolizard. This is wrong, as Sonic is the one who comments on the resemblance with him recalling the events of Sonic Adventure 2, and illogical as Lancelot has no in-universe reason to know the Biolizard.
Racing with Sonic 218 [Sonic & All-Stars Racing Transformed] Release Dates The Japanese Wii U release date is listed as "May 15, 2013" instead of 2014, while the Japanese PS3 release date is correct. Though the PS3 and Xbox 360 versions were released on the same day in North America and Europe, it isn't specified that out of the two, only the PS3 version was released in Japan.
226 Wisps The Blue Cube is erroneously called the "Blue Block".
Sonic Mania 254 Enemies A sprite of the Scarab is incorrectly used for the IceBomba.
256 Minibosses and subbattles Big Squeeze is erroneously stated to possess a laser cannon.
257 New Faces The Heavy Rider is erroneously referred to as male.
The Heavy King's description is missing a space between the words "aspirations" and "of".
Olympic Games Series 271 Dream Events It is stated that Mario & Sonic at the Olympic Games did not feature Dream Events. In reality, the game did feature Dream Events, although they were not set in either the Sonic or Super Mario universes.
The screenshot used to illustrate the Dream Snowboard Cross event in Mario & Sonic at the Olympic Winter Games instead uses a screenshot of the regular Snowboard Cross event.
The screenshot used to illustrate the Dream Fencing event from Mario & Sonic at the London 2012 Olympic Games instead uses a screenshot of the same event from Mario & Sonic at the Olympic Games.
The entry that elaborates the Hole-in-One Curling event from Mario & Sonic at the Sochi 2014 Olympic Winter Games lists its inspiration and origin from Green Hill Zone in the original Sonic the Hedgehog. In truth, the event is based on Green Hill from Sonic Generations.
Super Smash Bros. Series 277 How to Unlock The list of unlock requirements for Sonic jokes that "defeating ten enemies in Cruel Melee in Super Smash Bros. Melee is not one of them". This is a reference to the April Fools hoax from Electronic Gaming Monthly in their April 2002 issue. In reality, however, the hoax claimed that the player needed to defeat twenty enemies in Cruel Melee.
278-281 Cameos & Collectibles Hero Chao's appearance as a spirit in Super Smash Bros. Ultimate is not included anywhere in the section.
278-279 The appearance of Tails and Knuckles as trophies in Super Smash Bros. for Nintendo 3DS are not mentioned.
280 The section does not include Silver's appearance as a stage cameo in Super Smash Bros. Ultimate.
281 Espio's entries are not combined, resulting in two completely separate rows for his appearances.

Deluxe edition[]

In addition to the regular edition, a deluxe edition of Sonic the Hedgehog Encyclo-speed-ia was published. This special version includes:

  • An exclusive mosaic cover.[3]
  • A clamshell case featuring gold foil "Ring" treatment.[3]
  • A portfolio housing two archival gallery prints of Sonic and Dr. Eggman.[3]

Trivia[]

  • On page 157 in the New Faces section of the "Shadow The Hedgehog" chapter, the artwork of Amy appears to be edited. Her artwork from the game actually depicts an error in which her leg appears to be clipping out of her boot. In the book, it is edited to make it not look like so.
  • Ian Flynn has recognized the goofs and mistakes in the Encyclo-speed-ia and wishes that, if a second edition comes out, he could correct them alongside adding information about Sonic Frontiers. However, he clarified that he was not in charge of the selection of pictures, as he only wrote the text. While Sonic the Hedgehog Pocket Adventure was not included due to rights issues, he also acknowledged he forgot about Sonic Free Riders when writing the book.[9]
  • There is also a paperback version with an alternate front and back cover.
