* FridgeBrilliance: The [[FunWithAcronyms "Pure Evil Energy"]] the story refers to could actually be the Negative Energy of the Chaos Emeralds at work. Given Kintobor saw his machine (and thus his plan to rid the world of all evil) blowing up in his face, his despair at the situation he created combined with the machine, which was malfunctioning and meant to harness the power of the Emeralds, probably triggered his transformation into Robotnik and [[ModeLock left him stuck in that evil form forever]], not unlike the effects the Emeralds had on [[VideoGame/SonicAdventure the vengeful Chaos]] or [[VideoGame/SonicUnleashed the werehog form that served as a dark antithesis of Sonic's super form.]]
* FridgeHorror: Depending of whether [[ContinuityDrift you're willing to buy this as the backstory for the games, classic or modern, in any way]], it adds [[TearJerker a rather tragic subtext to the games]]--Sonic [[DownerEnding never succeeded in changing Ivo back into his old friend Ovi Kintobor]], and is constantly forced to fight the evil Ivo Robotnik for the rest of his life, with no hope of ever seeing the benevolent Ovi again, [[AndIMustScream whose personality is probably trapped inside of the evil Eggman forever, forced to watch helplessly as Sonic fights endlessly to fix his greatest mistake.]]
* GeniusBonus: The "cobalt effect" mentioned by Kintobor, referring to how Sonic's fur and quill color was changed into Cobalt Blue, is a reference to the metal cobalt. Compounds of cobalt are used to provide a deep blue color to glass, ceramics, inks, paints and varnishes.
* HarsherInHindsight: Ovi Kintobor's corruption into the evil Ivo Robotnik would be unintentionally paralleled [[VideoGame/SonicAdventure2 a decade later in the games]] when Eggman's grandfather, Gerald Robotnik, who started off as a benevolent, well meaning scientist, tragically became a [[OmnicidalManiac misanthropic monster]] by the death of his granddaughter at the hands of government soldiers, and decided to use the Chaos Emeralds, which he initially planned to use for a benevolent purpose--powering the Eclipse Cannon in order to destroy the [[VideoGame/ShadowTheHedgehog Black Arms alien race]] and save the world from them--[[EarthShatteringKaboom as a weapon to annihilate humanity instead.]]
* HilariousInHindsight: The story mentions the existence of a seventh Chaos Emerald that Kintobor has yet to find, even though the seventh Chaos Emerald wouldn't even become part of the games until ''VideoGame/SonicTheHedgehog2''.
