13	''Astro Boy: Omega Factor'' (Known in Japan as ''Astro Boy • Tetsuwan Atom'': ''Atom Heart no Himitsu'') was based on ''Manga/AstroBoy'', released in 2003 for the UsefulNotes/GameBoyAdvance after the anime's 2003 reboot. It was developed by Creator/{{Treasure}} and Hitmaker and published by Creator/{{Sega}}. Many consider this game a massive aversion of TheProblemWithLicensedGames, and a fitting tribute to Creator/OsamuTezuka.
14
15	The storyline starts off by following the 2003 anime, but soon diverges from it by adding elements from several other Tezuka stories. Dr. Tenma, brilliant robotics expert, [[WeCanRebuildHim rebuilds his son as a robot]] after he is killed in a horrible car accident. When he realizes Astro is not a true replacement, he abandons Astro and [[DisappearedDad disappears.]] After being adopted by Dr. O'Shay, Astro develops a sense of justice and sets out to resolve problems plaguing the relations between humans and robots.
16
17	In terms of gameplay, this is a BeatEmUp where Astro can jump and air dash ([[InvulnerableAttack he's invincible while dashing]]). Astro has a basic punch combo, although he may freely [[PunchedAcrossTheRoom kick enemies away]] or [[FingerGun fire a finger laser]]. He also has access to three special attacks that he can build energy for.
18
19	* [[WaveMotionGun The Arm Cannon]], easily the strongest weapon, but leaves Astro wide open to attacks from behind.
20	* [[MoreDakka The Machine Guns]] mounted on his lower backside will clear the screen of all projectiles and temporarily [[SmartBomb stun all enemies]], but is the weakest.
21	* [[MegatonPunch EX Dash]] has the smallest area of effect and the hardest to aim. But Astro will attack while dashing, juggling enemies everywhere as he hits them.
22
23	There are also a few ShootEmUp levels where Astro exclusively flies. He relies on his finger laser for offense, but can dash and use his specials normally.
24
25	Despite excellent reviews, this game was mostly passed over for the Playstation 2 game developed by Sonic Team and this fell into obscurity. However, those who did play the game [[CultClassic loved it.]] The ''Astro Boy'' game for the UsefulNotes/NintendoDS based on the American CGI film is inspired by this one, but unfortunately, it is widely considered to be inferior in every aspect.
26
27	----
28	!!Tropes used:
29	* AdaptationalNiceGuy: There's no mention of Tenma being neglectful towards Tobio and he didn't sell Astro to a circus. His ambition to create a God-like robot is also ultimately portrayed in a positive light.
30	* AirJousting: The battle with Blue Knight consists of a series of [=QTEs=] where he and Astro fly towards each other, try to land a hit, then turn around and repeat the process until one of them falls.
31	%%* {{Atlantis}}: Mu. [[spoiler:Rock]] remains in the past to try to save it, but it isn't shown if he succeeded in changing anything.
32	* AssassinationAttempt: At the beginning of stage 5, Deadcross, [[spoiler: A.K.A Rock,]] the leader of Black Looks, kills Rag with an explosive, which leads [[spoiler: to a five-year war between humans and robots that ends up with all robots being wiped out. Rag manages to survive in the new timeline, but he ends up becoming black mask, while his assassin Rock becomes president until his secret identity is discovered.]].
33	* AutoPilotTutorial: The game opens with a skippable tutorial about the hero's air dash, normal attacks, and super moves. When attacking the enemies, you must do as Prof. Ochanamizu says or he'll repeat the task for you.
34	* BackFromTheDead: [[spoiler:Astro and Nuka]] are revived by Phoenix after they die in the final chapter.
35	%%* BadassAdorable: Astro, Denkou, Pook and the list goes on...
36	* BadFuture: After a time travel adventure, [[spoiler:Astro Boy returns five years later to a world where the Robot War has left earth scorched and uninhabitable. His attempts to fight for justice in this environment are too little too late. On later cycles, he narrows the error level down to a more manageable 3 months]].
37	* BeatingADeadPlayer: In the moonbase stage, if you get killed, gravity will take a while to let Astro's body stay still on the ground. In the meantime, enemies will keep attacking Astro as if he were still moving.
38	* BerserkButton: Drake ''completely loses it'' when Astro inquires about his long-lost daughter Prime Rose, whom he believes to have been murdered by a robot. After this exchange, it becomes even more critical for Astro to uncover the truth of her supposed death before Drake can enact his campaign of revenge.
39	%%* BigBad: Sharaku Hosuke.
40	* BlindIdiotTranslation: In the 2003 ''Astro Boy'' anime, the character Epsilon was gender-swapped to a female. That's the version featured here, but all the English text in this game refers to her as a male like the manga's original.
41	* BoomerangBigot: True to most of his incarnations, Dr. Tenma openly views humans as weak and helpless, and feels that only a robot like Astro could truly guide them beyond the darkness. Cruel demeanor aside, it's pretty apparent that the loss of his only child really took a serious toll on him.
42	* BoringButPractical: The spin kick that ends a combo and blows most enemies away can be used anytime by pressing Down+B and is usually the best offensive option when Astro is being swarmed. It's not flashy or powerful like the Machine Gun special move, but it costs no meter to perform.
43	%%* BossBonanza: World's Strongest Robots.
44	* BossRush:
45	** "World's Strongest Robots" pits Astro against the five strongest robots in the world. A change from the Manga, where Pluto fights the world's strongest.
46	** "World's Greatest Adventure" pits you against Magnamite, the Artificial Sun, and Carabs in one single stage. After that, you face off against Sharaku and [[spoiler:Garon]].
47	* ButtCannon: Astro Boy has machine guns installed on his butt, which stun and damage every enemy on screen at the cost of a bar from the special meter.
48	* CharacterCustomization: The game gives no guidelines as to where to put your upgrades, but you'll max out by halfway through Rebirth if you find everyone. The only required customization is [[spoiler:having Level 3 Sensors when you get to Black Jack's house]].
49	%%* CharacterDevelopment: Atlas, though this can be seen as "re-development".
50	* ChargedAttack: Astro's beam cannon can be seen charging whenever the special is activated. It conveniently freezes time during the animation.
51	* ColorCodedForYourConvenience: You can tell the properties of each enemy by their color. Blue enemies fire projectiles and Red enemies have all attacks of their kind on top of not flinching to any attack but the machine gun.
52	* {{Combos}}: The game counts combos [[{{Cap}} up to 10]] and this acts as a score multiplier. However, racking that many hits is difficult because you're required to chain air dashes between each 4 melee attacks with great precision.
53	* CompositeCharacter:
54	** Rag and [[spoiler:Blue Knight]] are merged into a single character and both he and [[spoiler:Deadcross]] are now "played" by Rock, though originally they were just one-shot characters. Furthermore, Rock later [[spoiler:finds [[HeelFaceTurn redemption and love]] and decides to stay in Mu]], becoming the version of the character from the movie ''Marine Express''.
55	** Pook, the shape shifting robot from the ''Crucifix Island'' story is merged with Pick from ''MajinGaron'', while his working unwillingly for Skunk parallels Denkou (who also appears in the game but only as a minor boss with little role in the plot).
56	** Nuka combines elements from her original 80s anime incarnation as well as ''Prime Rose'''s Death Mask, Bem from the original series' ''Earth's Last Day'' storyline (humanoid control system for a weapon of mass destruction) and Mitchy and/or Tima from ''Anime/Metropolis2001'' (created on Duke Red's orders using the power of Omotanium, plugged into a machine that can affect the sun).
57	** Rainbow Parakeet is merged with Sherlock Homespun, the cyborg detective from the original ''Artificial Sun'' story.
58	** Brontus is a mashup of two different characters from the ''World's Strongest Robot'' saga, taking his chicken-like appearance from Montblanc and his fighting style from Brando.
59	** Sharaku as the game's BigBad is mainly based on the EvilOverlord of ''Marine Express'' but in a post-ending scene, he becomes the original version of ''Manga/TheThreeEyedOne''.
60	** Shadow, a villain from the 2003 anime, appears in the BadFuture as the leader of the robots. [[spoiler: He turns out to be Sharaku in disguise.]]
61	** Atlas being a cyborg created from Daichi Tokugawa's brain after he suffered radiation poisoning from Omotanium exposure during Death Mask's construction recalls Go Gan, the patient in the ''Manga/BlackJack'' story ''The Painting is Dead'', an artist given a brain transplant to save him from dying of radiation sickness after being caught in a nuclear bomb test.
62	* ContinuingIsPainful: Downplayed. Your score is reset upon continuing... but you're also given full life and special attacks (no doubt a relief considering this game's difficulty), in contrast to Treasure's ''Gunstar Super Heroes'' and ''Advance Guardian Heroes''.
63	* CowardlyBoss: Denkou spends the entirety of his fight running from Astro while dropping timed bombs. He's also invisible and untouchable until Astro slaps a certain amount of devices set around the looping room.
64	* CrossOver: Starring Astro, with other characters from Creator/OsamuTezuka's [[ReusedCharacterDesign star system]] showing up as support characters and villains.
65	%%* CuteBruiser: Astro and Pook, the transforming robot.
66	* DefeatMeansFriendship: Blue Knight and the world's strongest robots become allies on the timeline where they do not [[DefeatEqualsExplosion explode by Astro's fist]].
67	* DiscOneFinalBoss: Pluto is the final boss of Birth. He even has the same music as the TrueFinalBoss.
68	* DoesThisRemindYouOfAnything: Non-sexual variant. The robot/human conflict in the Antarctic appears ''very similar'' to the segregation debates and Civil Rights Movement in the 50's and 60's. As well it should, considering the original manga story it's based on was written during this period.
69	* DoNotAdjustYourSet: [[spoiler:Drake broadcasts his message to Nuka, ordering her to initiate the Death Mask and obliterate all robot-kind so her father won't die, on all world channels.]]
70	* DownerEnding: [[spoiler:The first playthrough ends with Death Mask killing Astro and all other robots on Earth. Fortunately, after this, the player is given the ability to shoot for a far less depressing ending.]]
71	* EarnYourHappyEnding: Astro has to use the Time Skip ''liberally'' in order to set right all that is wrong. He eventually achieves an ending far brighter than most versions of his story, with good outcomes for practically everyone.
72	* EvenEvilHasLovedOnes: Drake's love towards his daughter Prime Rose [[spoiler:and his grief over losing her is what drives him to be racist against robotkind and commit crimes against them. He peacefully surrenders once he learns Rose is cured of her disease and explains to him what happened.]]
73	* FantasticRacism: Anyone in the game who's actively seeking to destroy robotkind, most notably Drake and Rock. And this is not limited to the evil characters either, as not all of Astro's allies see robots as true equals.
74	* FinalBoss: [[spoiler:Garon, a giant composed of "living metal" that is being controlled by Pook under Sharaku's orders.]]
75	* {{Foreshadowing}}: Kin Sankaku and Skunk found Pook while digging for the secret treasure of Mu. At the end of the game, it's revealed that [[spoiler:he IS a part of the secret treasure of Mu — Garon]].
76	* GiantMook: You'll often find both tiny and double-sized enemies through the game, which gets rather odd when it comes to the human Black Cross ones. Naturally, their attack power matches their size.
77	%%* GrimyWater: Only at some points of the 2nd Stage and it seems to be normal water.
78	* GrotesqueCute: [[spoiler:Nuka while in Death Mask form. A disturbing face-shaped ship with her usual sweet personality.]]
79	* GroundhogDayLoop: Astro eventually gets the ability to warp to any point of time in the loop he wants to go.
80	* GuideDangIt:
81	** Some of the hidden Omega Factor characters are frustratingly hard to find. While Level 4 Sensors help (Astro will point out when a character is in a given segment), you'll still be spending a lot of time looking around. It doesn't help that at least one (Magma) is required by the plot, though given the stage you find him in, it's likely you'll blow open his hiding place anyway while beating up {{Mooks}}.
82	** An entire subplot is initiated in a rather unintuitive manner: [[spoiler:by ''repeating the tutorial level'', since that's the only place barring cutscenes where Astro interacts directly with Dr. O'Shay (Astro will confront him about Dr. Tenma). Made worse by the fact that the game discourages you to do so to begin with by having O'Shay ask if you've forgotten the basic controls when you start]].
83	** The Blue Knight duel. You can't just press the button, you need to keep holding it down until the joust ends.
84	** Kennedy will only tell you the whereabouts of Dr. Black Jack after you [[spoiler:beat Blue Knight in the Antarctic duel, drive Sharaku off Fire Vase Island, and fight Atlas once more after hearing Drake's motive]].
85	** Figuring out how to damage North at all in his first phase. Hitting him only results in his arms blocking you, and using your laser causes him to unleash a powerful and nigh-unavoidable counterattack. You actually have to hit him first, and '''then''' use the laser on his eyes while one of his hands is still out.
86	* HardModeFiller: The second half of the game is the same levels as the first half again, but with tougher enemies, and you have to find a hidden character in each one.
87	* HaveWeMetYet: How Pook is introduced. Later on, when Astro is transported back in time to Mu, it's Pook who doesn't recognize him. And in the NewGamePlus, when you go back to the moment of their first meeting, they recognize each other.
88	* TheHeroDies: [[spoiler: Astro dies in the first ending as a victim of Death Mask. Fortunately, for him, he's resurrected.]]
89	* HitPoints: By the three-quarters point of Rebirth, they stop mattering, as enemies are often able to kill Astro in two or three hits anyway.
90	* HollywoodAtheist: One important quest has Astro proving wrong an archaeologist, Boon, who doesn't believe in anything that cannot be proved by science. [[spoiler:By calling up Magma who is very advanced and is somehow neither animal nor machine, according to Boon himself.]]
91	* IAmAMonster: Atlas describes himself as one in Birth.
92	-->'''Atlas:''' Just look at me! I'm neither fully human nor fully robot! '''I'm a monster.'''
93	* ImmuneToFlinching: Red enemies are never stunned by attacks (except for the machine gun). Purple enemies also have this property, but they are much rarer.
94	* ItsAllMyFault:
95	** After having his true self reawakened, Atlas takes full responsibility for Prime Rose's disappearance, even offering his life to Drake. Instead, Drake abandons his hatred for robots and asks Atlas to watch over his daughter.
96	** Played with with Duke Red; he was the one to commission the Death Mask as a last resort if robotkind ever took up arms against humanity. After his near-fatal encounter with the vengeful Blue Knight, he realizes that he bears much of the blame for why a fallen hero such as he would come to resent humanity.
97	* KarmaHoudini: [[spoiler: The first and worst bad ending ends with Sharaku suffering no repercussions as he abandons the timeline to re-start his attempt at world domination on another timeline with the implication that he had done it countless times, leaving Astro to his death]]
98	* KarmaHoudiniWarranty: [[spoiler: Astro eventually figures out Sharaku's true motives and manages to ruin his plans on the good ending. When Sharaku tries to undo the timeline and start over during the post-credits, his third eye is sealed away by Wato Chiyoko.]]
99	* LetsYouAndHimFight: Astro fights several heroes[=/=]investigators who think Astro is a criminal, or they're the type who fight first and ask questions later.
100	* LevelUpFillUp: Adding someone to the Omega Factor restores your health. However, each health recovery only works once and this seriously unbalances the difficulty of subsequent playthroughs.
101	* LighterAndSofter: The game reads like a FixFic from people who felt bad for all the suffering Astro endured in the original manga and its animated adaptations, but his road to triumph is a hard one nevertheless.
102	* LuckySeven: Astro's Seven Super Powers are fittingly called his "[[VideoGame/GunstarHeroes Seven Forces]]" here. Pook plays the role of Seven Force in this game, but he only displays 4 forms in his boss battle regardless of difficulty mode and a fifth one later [[spoiler:as the final boss]].
103	* LuckilyMyShieldWillProtectMe: On Stage 6 there is no way to pierce the guard of enemies who are raising their shields.
104	* MassiveMultiplayerCrossover: Has all of Tezuka's characters as cameos.
105	%%* MultiMookMelee: So much the game lags A LOT because of it.
106	* MistreatmentInducedBetrayal: Rag used to be Rock's substitute in his presidential meetings until he became tired of being used as his puppet and got ordered to shut up when he began to question his anti-robotic policies.
107	* MusicalGameplay: A minor example. While hitting enemies into each other does produce increasingly high-pitched xylophone sounds, they're not particularly synched to the music or anything else.
108	* MurderByInaction: Sharaku abandons Astro to his demise the first time the Death Mask is activated.
109	* NewGamePlus: The entire second half of the game is reached after beating it once.
110	* NiceJobFixingItVillain: Rock's murder of Rag in the original timeline ends up triggering a world war between humanity and robots. By the time Astro returns to the present, or rather five years after the fact, the majority of the planet has been destroyed and even with the activation of Death Mask, human civilization is effectively shattered.
111	* NoFinalBossForYou: The first time through the game you cannot access the final stage. Finishing the game again lets you access TheVeryDefinitelyFinalDungeon.
112	* ObviouslyEvil: Subverted. Drake has an EvilMustache, but [[DarkAndTroubledPast he wasn't always as bad as all that, as we later find out...]]
113	* OffscreenStartBonus: [[spoiler:Kennedy, Unico, and Mars]] are just off-screen when you start certain areas.
114	* OneHitKill: Many enemies and most bosses in Hard Mode can defeat Astro in one hit. Even in Normal mode, the giant roboid in stage 0-3 will kill you with one strike.
115	* OneStatToRuleThemAll: The "Jets" and "Laser" stats are the only two that are useful in both the platforming and shoot 'em up segments of the game.
116	* PaletteSwap: The game does this with every single mook and even some mid/mini-bosses, to differentiate their attack patterns and properties.
117	* PatrickStewartSpeech: Dr. Tenma delivers one in the good end, rousing Astro to lead humans and robots to a bright future. Before that, Manga/BlackJack delivered one to him, talking about how important emotions are for humans.
118	* PeggySue: After the first run through the game, [[spoiler: Manga/{{Phoenix}} saves Astro and grants him TimeTravel so he can SetRightWhatOnceWentWrong.]]
119	* PhlebotinumBomb: The Death Mask is capable of firing Omotanium-powered beams that destroy electronic components. It uses this to [[spoiler:exterminate all robots on Earth during the first ending. This beam is an instant kill during the second fight against Sharaku]].
120	* PlotCouponThatDoesSomething: Time travel (the Stage Select) is how Astro saves the world.
121	* PragmaticAdaptation: The original "Black Looks" crooks in the ''Astro Boy'' manga wore masks that looked like odd [[BlackfaceStyleCaricature blackface-looking]] creatures. This version where they work for Deadcross simply shows them with regular human faces hidden by their hats casting some shadow. Their character sheet even specifies that their mask was redesigned for this game.
122	* PresidentEvil: Rock starts off as this in the timeline where he does become President of the Antarctic in the alternate timeline; he gets better though.
123	* ReasonableAuthorityFigure:
124	** Duke Red as the International Councilor. It becomes darkly ironic that he, a champion for the rights of robotkind is also the man responsible for the creation of the Death Mask in the event of a robotic uprising against humanity.
125	** Dr. O'Shay is a far more rational and understanding man than his disillusioned predecessor, Dr. Tenma.
126	* RobotWar: During the five years Astro was absent due to traveling to the past, the robots declared wars on humans, principally due to avenge Rag's assassination, which resulted in 80% of the earth being destroyed.
127	* RoleSwapAU: In the "Greatest Robot in the World" storyline and its various adaptations, Pluto hunts down and fights the most powerful robots in the world, with Astro trying (and failing) to stop him. In stage 7, "World's Strongest Robots", the robots destroyed in that arc appear as Pluto's henchmen, with Astro being the one to fight them.
128	* RPGElements: Understanding a character's personality lets Astro unlock some of his true potential — health, attack power, number of times he can dash, and how good his super senses are.
129	* SanitySlippage: Drake suffered this big-time after he was led to believe that his daughter had been killed by a robot while awaiting treatment for a highly fatal disease. He only gets worse after Astro confronts him with this fact, and is willing to murder Duke Red ''along with himself'' in order to enact revenge on all robotkind for his loss.
130	%%** The Blue Knight is suffering from this as well; it becomes evident as to why once we learn his real identity.
131	* ScoringPoints: The game has various high scores and best timetables for each level on the three difficulties. It also records if you were able to beat a chapter or the entire game without dying. Your {{combo}} meter acts as a ScoreMultiplier which goes up to 10 (4 B hits, finger laser, special attack), so you should use your specials every now and then to their best effect.
132	* ShadowArchetype: At one point Astro claims that Atlas is this to himself, saying he's gone mad from his grief and sorrow as opposed to controlling his emotions as Tenma intends them to.
133	* SetRightWhatOnceWentWrong: [[spoiler:The second half of the game as Phoenix revives Astro and sends him back in time to make sure Death Mask doesn't activate and kill all the robots. With knowledge of the previous timeline, Astro does things a little different this time.]]
134	* ShesAManInJapan: This game refers to Epsilon with male pronouns, but uses the character's design from the 2003 anime, in which she is female.
135	* ShoutOut:
136	** In addition to Tezuka works, the game is jam-packed with references to previous Treasure game ''VideoGame/AlienSoldier''. For example, the Artificial Sun has been redesigned to resemble one of AS's minibosses and Majin Garon fights almost exactly like Z-Leo.
137	** References to ''VideoGame/GunstarHeroes'' are present: the background in one level features buildings that have signs reading "'''Gunstar'''", Pook refers to his different forms as "Forces" (similar to the ''Gunstar Heroes'' boss Seven Force), Astro's six main stats plus the Omega Factor are called "The Seven Forces", and the ending theme is a slightly slower version of ''Gunstar Heroes'''s ending theme.
138	** The Mu level has a secret alcove containing [[http://i.imgur.com/qyEh0Mz.png an enemy]] with a face exactly the same as the Clancers from ''VideoGame/MischiefMakers''.
139	** During the boss fight with Epsilon, one of her attacks has her summon a pod of dolphins as well as a static graphic of a blue whale, all of whom are animated and designed the exact same way as ''VideoGame/EccoTheDolphin''.
140	* ShownTheirWork: The unlockable Character List gives descriptions of all the characters and explains how they were adapted into the game.
141	* TheSixStats: The stats Astro can level up by meeting people include Life (determines his HP), Punch (determines the strength of his punch and kick), Laser (determines the strength of his finger laser and arm cannon), Jets (determines how many times he can [[VideoGameDashing use his jets]]), Shot (determines the strength of his machine gun super), and Sensors (determines how much Astro can see in certain levels).
142	* SolarCPR: After the battle with the game's TrueFinalBoss, [[spoiler:remains of it end up corrupting the sun. Astro has to send over a remnant of Death Mask/Nuka to restore it.]]
143	* SparedByTheAdaptation: [[spoiler:Nuka willingly sacrifices herself by asking her creator to dismantle her rather than kill countless others by detonating in "Astro's First Love", and dies for good. Here she gets resurrected by the Phoenix after sacrificing herself alongside Astro to save the earth, getting a happy ending as Astro carries her back home.]]
144	* StealthMentor: [[spoiler:Dr. Tenma]]'s ultimate goal is to get Astro to become stronger by overcoming adversity.
145	* SwordOfDamocles: [[spoiler:Death Mask]] was created to be this, in order to prevent robots from destroying humanity. This is why it is the biggest obstacle to Sharaku's plan to [[spoiler:conquer the world by instigating a robotic uprising]].
146	* TacticalSuicideBoss: [[spoiler:Garon]] would be invincible if its pilot didn't occasionally open his cockpit to check on the outside for no reason.
147	* TakingYouWithMe: Drake attempts this with Duke Red after taking him hostage, after his bid to blackmail Nuka into activating the Death Mask to annihilate all robots on Earth fails. He is only stopped when his daughter Prime Rose reveals herself to be alive and well, having been resuscitated at the last possible moment by Dr. Black Jack.
148	* TalkToEveryone: In the second half of the game, the player needs to find and talk to certain [=NPCs=] in a specific order to reach the following levels. [[GuideDangIt You're bound to need a guide]].
149	* TeamMemberInTheAdaptation: Denkou, an unrelated robot in the source material, is part of the game's version of the world's strongest robots.
150	* TheStinger: After "The End" appears, wait several minutes without pushing any buttons; and a short scene will give Sharaku's Factor.
151	* ThrowTheDogABone: After Daichi's reawakening after Prime Rose's successful revival, Dr. Tenma returns his original body to him, frozen in stasis and thus granting Daichi, aka Atlas, the chance to return to his former life.
152	* TimeTravel:
153	** The main element of the second half of the game. Astro needs to travel through time to figure out how to save the world and who the mastermind behind the war is.
154	** In the first ending, Sharaku confesses to Astro that he has already destroyed many timelines due to his vile actions forcing Death Mask to kill all remaining robot live, before abandoning him by traveling to another timeline where he couldn't be affected.
155	* UnwittingInstigatorOfDoom: [[spoiler:Atlas]], or rather his true self [[spoiler:Daichi]] had taken Prime Rose from the hospital while disguised as a robot to fulfill her wish to see the moon. During their voyage, he had suffered fatal exposure to Omotanium and was thus recreated into his current self, without any memory of his former life. It is this fateful encounter that directly leads to Drake's quest to destroy Robotkind to avenge his daughter, who he believed to have been murdered.
156	* VideoGameDashing: Astro can cancel most of his moves into an invincible air dash, but it still has a small delay you must account for.
157	* VideoGameTutorial: It's skippable, but if you do, then you miss out on an Omega Factor upgrade at the end. [[spoiler: On the NewGamePlus, this level is mandatory to revisit in order to unlock Tenma's house, a crucial location in order to get the good ending]]
158	* WakeUpCallBoss: The first proper boss, Magnamite, is a huge target that kills in three to four hits and must be dealt with very carefully. When it is low on health, it starts jumping all over the place to crush Astro against either edge of the screen. This kills in [[OneHitKill one]] to two hits and is done so fast that is practically enforces the use of super moves to finish it off.
159	* WarmUpBoss: The stoplight and giant spider minibosses in the beginning are quite predictable and don't do a lot of damage.
160	* WhamLine: Duke Red reveals the true nature of Death Mask: [[spoiler:"'''Nuka''' is Death Mask."]]
161	* WhamShot: The appearance of Death Mask, who then proceeds to [[spoiler:''destroy Astro and all robots on Earth''. Just when it seems that all is lost, you are given a second chance by the Phoenix]].
162	%%* WhatIsThisThingYouCallLove: Astro gets a bit of this the first time he runs into Nuka.
