Cool Car: Janperson's Dark Jaycar. It's a modified C3 Chevy Corvette that contains a detachable helicopter called Sky Jaycar. The Dark Jaycar and the Sky Jaycar have a maximum speed of respectively 700 kph (434 mph) and 1,800 kph (1118 mph),. Additionally, the car is equipped with a cannon called Land Jaycar that pops out when Sky Jaycar detaches from the car.
Dynamic Entry: Janperson loves these, and usually introduces himself by throwing a JP Card into a wall, or a gun, or a robot... (He doesn't quite fit the Death Dealer trope, as he only uses them to announce his presence.)
Gun Gibson likes to end his sentences with "baby".
The Gunslinger: Gun Gibson loves to twirl his guns, and manages to fit all four types of this trope at one point or another.
Huge Guy, Tiny Girl: Gun Gibson and Carol — they'd enter scenes with her riding on his shoulder.
It's Personal: George Makabe (the Big Bad of Neo-Guild) personally killed Gun Gibson's partner Carol, and it takes some convincing from Janperson to talk him down from an indiscriminate Roaring Rampage of Revenge to a "Best Served Cold" approach. (There are many civilian robots that use Neo-Guild parts without actually having anything to do with Neo-Guild.)
Judge, Jury, and Executioner: What Janperson was designed as and in fact still does, albeit mostly with crimes and criminals too far above what the local police can handle. A rather mild version when compared to Jiban.
Large Ham: Shun Sugata's performance as Tatewaki/Bill Goldy is pure, delicious ham.
Laser Blade: Averted, oddly — the Jan Blader is a solid metal sword.
Monster of the Week: Barely any of them show up, since robot technology in this version of Japan has basically advanced to the point that the Mooks are just as dangerous, however the series could be classified as having a Cyborg of the Week, which usually never shows up after the episode in which Janperson defeats them.
Morality Chain: Mostly averted. Gun Gibson is reasonable enough that Janperson only had to be this in the very beginning of their partnership.
Janperson doesn't appear to have this, nor does he seem to be Three Laws Compliant — he certainly ignores the second law on a daily basis!
Gun Gibson even less so, but he'll incapacitate human opponents with slightly-less-than-lethal force and leave them for the actual police.
Ridiculously Human Robots: Robots superficially resembling humans are somewhat common in the show, and one episode revolves around a human robot hunter trying to find parts for one built in the image of her brother, but overall they tend to be hitmen or assassins. Janperson himself could, with some work, pass as a human in a suit, as his A.I. is sufficiently advanced. To clarify: Janperson's movements tend to be jerky and obviously robotic (he's jumped from a building and landed on two feet), but in at least one case he's donned a robot disguise and acted surprisingly more fluid than usual.
Shapeshifter Mode Lock: Janperson can remove his face mask and wear clothes when necessary, which also lowers his output significantly. One episode featured him getting locked like this, with an apparently human exterior on top of that (that of a criminal).
Janperson's occasional costume change (removing his face guard and putting on clothes) is similar to what Robot Detective K did, but for a slightly different reason — JP mostly does it as a disguise, while K does it to avoid frightening people.
Unexplained Recovery: Bill Goldy is destroyed, but somehow returns for the ending of Juukou B-Fighter. Gun Gibson is also heavily damaged towards the end, but gets repaired in time for the finale.
Unusually Uninteresting Sight: Robots are quite common in this version of Japan, enough so that Janperson can disguise himself (or at least not draw as much attention) by removing his face mask and donning clothes.
