''Photon: The Idiot Adventures'' is a 6 episode anime OVA by {{Creator/AIC}} and manga series by Koji Masunari.

The main character, Photon Earth, is a young child who possesses superhuman strength, but is a bit simple-minded. While tracking down his childhood friend Aun Freya, who has stolen "the sacred artifact" (a marker) AGAIN, he gets lost and accidentally finds a crashed (space) ship. Made cranky by the fact that Aun ran off after he caught her, ''and'' by the fact that she wrote "UsefulNotes/{{Baka}}[=/=]Idiot" on his forehead while he was sleeping, ''he'' starts scribbling "Baka/Idiot" all over the walls of the ship in a rage.

Eventually he writes it on the forehead of Keyne Aqua (who was in stasis after escaping from Sir Papacharino Nanadan) and then falls asleep on her, because she reminds him of Aun's older sister (who took care of him when he was young -- but moved away after getting married). Neat little fact about marriage in that galaxy. Instead of giving each other rings, the guy will "claim" the girl by tattooing the symbol on his head onto hers. And guess whose doodling just activated the ship's wake-up routine?

Not to be confused with the "[[DuelingProducts other]]" major [[Series/{{Photon}} laser tag game franchise]] of TheEighties, or the live-action SciFi series (made to promote the previously mentioned game) produced by Creator/DiCEntertainment[[note]]with miniatures made by regular AIC collaborator Artmic[[/note]].

!!This show includes:

* AccidentalMarriage: When Photon, who had the word "Baka" drawn on his forehead by Aun, takes out his frustration by drawing it on an unconscious Keyne. Where Keyne comes from, drawing your partner's crest signifies marriage. [[spoiler:Also done at the very end to Aun, Lashara, and Keyne (again, after it was erased by Papacharino's meddling), but Photon still doesn't understand the significance.]]
** Sort of. By that time, he did it because he understood it meant [[LoveYouAndEverybody he loved them]], but is still rather clueless on the details.
* AccidentalPervert: When Keyne strips as she searches for the tracker Papacharino put on her, he starts to rise out of the floor and is accidentally treated to a "nice view" for a few seconds.
** He then [[DistractedByTheSexy pauses for a few more seconds to enjoy this view]], giving her a chance to destroy the tracker and escape (briefly).
* AGodAmI: Papacharino's ambition and reason for chasing/abducting Keyne.
* AllMenArePerverts: Papacharino tries to convince Photon to help him peek in on the Women's bath, citing this as Man's Duty.
* ArmorIsUseless: All the Brain Crystals in the universe can't stop a punch from Photon.
* CarryABigStick: Photon's weapon of choice.
* TheChessmaster: [[spoiler:The Galactic Emperor]]
* CluelessChickMagnet: Right to the very end, Photon is still unaware of what the female attention on him means. [[spoiler:Or that he's effectively [[MarryThemAll married three women]] at the very end.]]
* FanDisservice: Any shot of Papacharino's lower half.
* {{Fanservice}}
* FullFrontalAssault: When Keyne wakes up in front of Photon, she immediately goes on the offensive and attacks. It takes her a while to remember that she's completely naked.
* {{Gainaxing}}
* [[ViewerGenderConfusion GenderConfusion]]: In an in-universe example, [[spoiler:Pochi (all of them, it seems)]] are actually [[spoiler:women]], which surprises even [[spoiler:Papacharino, their master/employer]].
* [[SheIsNotMyGirlfriend He Is Not My Boyfriend]]: Aun says this about Photon whenever it's brought up.
* HotSpringsEpisode
* IdiotHero: Take a wild guess.
* LargeHam: Papacharino Nanadan.
* LethalChef: Keyne, possibly Aun as well.
* LukeIAmYourFather: [[spoiler:The Galactic Emperor is Keyne's father, and Lashara is ''not'' his daughter.]]
* TheManBehindTheMan: [[spoiler:Bulan, aka the Galactic Emperor]]
* MeaningfulName: Keyne Aqua is [[spoiler: ''the key'' to unlocking the hidden power of the gods.]]
* MegatonPunch: Papacharino is on the receiving end of this quite a bit.
* [[spoiler:MyDeathIsJustTheBeginning]]: [[spoiler:The Galactic Emperor deliberately allowed himself to be assassinated by Papacharino.]]
* NakedPeopleAreFunny: Nudity is PlayedForLaughs just as much as it is for fanservice. One notable example is when Papacharino is communicating with his fiance...while hiding the fact that he's wearing no pants and that there's a naked woman in the room with him that he was [[YourCheatingHeart just having sex with]].
* NoSell: Most of the setting's {{Magitek}} and superpowers are based on Aho energy. Photon happens to be the focal point of anti-Aho energy, which allows him to NoSell any Aho-based effects (and gives him SuperStrength).
** And [[BigBad the Emperor]], knowing this, uses anti-Aho energy against Photon, which everyone else is immune to.
* PhantomZonePicture: Aun gets trapped in one of these by [[spoiler:Bulan]]. However, she still manages to punch Papacharino's head until it ''bleeds''.
* PunnyName: There is the plot-central Aho energy; aho and baka both mean, roughly, idiot.
* TheReveal
* SandWorm: One attacks a frightened Pochi, only to be skewered by Photon and devoured.
* ShooOutTheClowns: InUniverse example, when the BigBad, who's been manipulating the protagonists from the start out of boredom, [[CurbStompBattle effortlessly crushes Papacharino]] and tells him to take a hike.
-->'''[[spoiler: Emperor]]:''' I enjoyed having you as my jester, but this next scene is a bit too serious for you.
* SkinshipGrope
* SuperStrength: Half of Photon's superpower.
* [[spoiler:SwitchedAtBirth]]: [[spoiler:Keyne Aqua]] and [[spoiler:Lashara Moon]].
* TattooSharpie: Photon is so annoyed after his sister writes "idiot" on his forehead that he does the same to a MysteriousWaif that he discovers in suspended animation. Although the visible markings eventually go away, it becomes a ChekhovsGun when [[spoiler:the Big Bad tries to transform her into a power source that will give him godlike abilities, and the marking confuses the computer and screws up the process.]]
* TertiarySexualCharacteristics: [[spoiler:Pochi-One has a bow in her hair]].
* ThanksForTheMammary
* {{Tsundere}}
* ATwinkleInTheSky
* WithGreatPowerComesGreatInsanity: [[spoiler:The Galactic Emperor reveals that he was bored with galactic conquest and wanted some new excitement]].
