[[caption-width:337: We can remake him, faster, stronger, more destructive and... better at farming?]]
->''"I've become a remodeled human to perform the best agriculture in Japan... no, the world. My name is the farming cyborg... Cyborg Grandpa G!"''

One day, Tokijirou Kaizou, a 70-year old man, decided to convert himself into a cyborg to become the greatest farmer in the world. His family is as baffled as the audience.

An early work by Takeshi Obata, one half of the ''Manga/DeathNote'' duo. It's probably the only reason why anyone knows about this.

!!Provides examples of:
* [[AmazinglyEmbarrassingParents Amazingly Embarrassing Grandparent]]: It's class inspection day - everything's been polished, the pupils are on their best behaviour, even the teacher has [[SheCleansUpNicely cleaned up]] - then Kei's grandfather (guess who) smashes through the window and embeds himself in the blackboard in the shape of a G.
* BadassGrandpa: Obviously.
* BeyondTheImpossible: G-chan doesn't agree with your interpretation of the word "impossible".
* {{BFG}}: Subverted. Doctor Sharekoube takes impressive looking inventions and manages to make them ''less'' threatening.
* CardCarryingVillain: Sharekoube-sensei tries so very hard.
* CallingYourAttacks: Which change just about every time, and are usually ridiculously named.
* CloudCuckooLander: "I did my research watching anime!"
* CoolShades: Just take a look at that picture up there.
* EyeBeams: Just one of Tokijirou's many powers.
* FanService: Most female characters. Except the old ones.
* FanDisservice: Grandma's ''boobs'' hangs outside her armor...yes, hang...
** Her young version is pure FanService, however.
* ForScience: Averted. His great scientific/technological prowess is dedicated entirely to furthering agriculture... which is technically a science... right?
* GambitRoulette: Buh... the tractor... part of ThePlan all along? How is that even ''possible''?
* GatlingGood: Minigun scarecrows. Yes.
* HappilyMarried: Grandma, Grandpa, Father, Mother.
* HotBlooded: [[SuperMode STRONGER G]]!!!
* InstantArmour
* InstantAwesomeJustAddMecha
* MadScientist: The titular character turns himself into a cyborg over the course of two days... [[ForScience FOR AGRICULTURE!]] Sharekoube is a more extreme example in his younger days, but has grown senile in his old age.
* {{Mecha}}: the tractor turns into one in an emergency... for some reason.
* MoreDakka: Part of Grandpa's schtick seems to be adding guns, armor and overpowered engines to anything with the structural fortitude to withstand it, including himself. The scarecrows are reminiscent of something out of ''{{Transmetropolitan}},'' and both his farm and his new house in the city are quickly outfitted with a terrifying arsenal that could probably take down a small battalion.
* MundaneMadeAwesome: Even to the people who love it and have done it all their lives, farming is a tedious and time-consuming activity, but not when G-chan does it!
* NewPowersAsThePlotDemands: If G-chan needs to do something, he just build himself a new invention or makes a new modification to his body.
* NoOSHACompliance:
** ''No one'' can work on Tokijirou's farm, since he forgot to disable the defense grid after he left. It wasn't exactly safe for his family when they still lived there.
** When he tries to get a part-time job, it doesn't take long for him to attempt to make "improvements" to his workplace.
* OldMaster: Tokirjirou can not only kick your ass, but will out-invent you any day of the week.
* PresidentEvil: The Mayor.
* RefugeInAudacity: The only way G-chan gets away with most of his activities is by living in a world that seems to fear giving him any sort of retribution. Otherwise he would be in jail for ''all sorts'' of crimes. That ''may'' be the case, since he did take out a Godzilla-like monster.
* RuleOfCool[=/=]RuleOfFunny: The defining rules of this universe, since the laws of physics and the entire nation of Japan have clearly stopped working.
* StealthPun: Grandpa calls himself "G-chan." The word "ji-chan," pronounced the same way, means "grandfather."
* StuffBlowingUp: ''All the time,'' for no apparent reason except that Grandpa thinks it's a good idea. Also 'cuz [[RuleOfCool it's awesome.]]
* [[SuperRobot Super]] {{Cyborg}}
* TechnicalPacifist: G-chan's rivalry with Sharekoube is a result of a disagreement over how cybernetics ought to be used. Sharekoube wanted it for military purposes and Tokijirou for agricultural purposes. Of course, G-chan causes way more destruction with his "non-military" inventions than Sharekoube ever does with his "weapons."
* ThereIsNoKillLikeOverkill:
** Grandpa's response to there being crows in his field? ''[[ImpressivePyrotechnics Blow up the field.]]''
** The tractor with the fighting power of an ''F-16.''
* TimTaylorTechnology
* ToiletHumor: Grandpa's cyborg body runs, in part, on manure. The byproducts of this are used to... [[{{Squick}} interesting effect.]]
