''Photon: The Idiot Adventures'' is a 6 episode anime OVA 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 "{{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 laser tag game franchise of TheEighties, or the live-action SciFi series (made to promote the previously mentioned game) produced by Creator/DiCEntertainment.

!!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.]]
* 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.
* ATwinkleInTheSky
* {{Baka}}: It's called ''The Idiot Adventures'' for a reason. Practically all of the main characters exhibit some type of stupidity.
* CarryABigStick: Photon's weapon of choice.
* TheChessmaster: [[spoiler:The Galactic Emperor]]
* FanDisservice: Any shot of Papacharino's lower half.
* {{Fanservice}}
* {{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]].

* HotSpringsEpisode

* 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.]]
* NoSell: Most of the setting's {{Magitech}} 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''.
