[[caption-width-right:300: '''[[CatchPhrase WE'RE BAD!]]''']]

->''President [[UsefulNotes/RonaldReagan Ronnie]] has been kidnapped by ninjas. [[MemeticMutation Are you a bad enough dude to rescue the President?]]''
%%(yes, that is a mashup between the arcade and NES versions, but we wanted to mention both, okay?)

A side-scrolling BeatEmUp by Creator/DataEast for the UsefulNotes/{{arcade|Game}}s and ported to the UsefulNotes/NintendoEntertainmentSystem. The plot, [[ExcusePlot such as it is]], goes as follows: There are rampant ninja-related crimes these days, and the White House is no exception. A guy who [[Creator/ArnoldSchwarzenegger looks like he could be]] VideoGame/DukeNukem's uncle informs you that the President has been kidnapped by {{ninja}}s, and asks you if you are a bad enough dude to rescue the President. The correct answer is to [[ConservationOfNinjutsu beat up an army of ninja]], while shouting "I'M BAD!!!", and repeat until the President is rescued. Said President thanks you for your troubles, and suggests burgers for lunch.

[[http://www.kickstarter.com/projects/pinstripegames/bad-dudes-2 There was a crowdfunding campaign for a sequel.]] Sadly, it never reached its goal.

!!Are you a bad enough dude to provide examples of tropes?

* AWinnerIsYou: "Hey dudes, thanks for rescuing me. Let's go for a burger.... Ha! Ha! Ha! Ha!"
* AdaptationNameChange: Some of the bosses are named differently on the Famicom version's manual compared to the enemy roll call in the end of the Japanese arcade version.
** Iron becomes Nenail
** Akaikage becomes Killer Joe
** Devil Pole becomes Kon Bōsai
* AntagonistTitle: The game is known simply as ''Dragon Ninja'' in Japan.
* BlindIdiotTranslation: Especially the arcade version. "Rampant ninja-related crimes these days. White House is not the exception."
* TheCameo: VideoGame/{{Karnov}}, hero of his self-titled Data East game, is the first stage's boss.
** [[DegradedBoss He later reappears as a normal but tough enemy]], sporting the same grey coloration he has in the NES version after he's taken damage. His official name is "Kusamoci Karnov".[[note]]Kusamochi is a green Japanese rice cake made from a type of leaf.[[/note]]
* CatchPhrase: "I'm BAD!" Or through the NES's sound system, "GWAM BAAA!"
* CollisionDamage: Most of the mook ninjas don't bother to attack the player but instead just run through him to do damage.
* ColorCodedMultiplayer: In the arcade version, Player 1 wears white parachute pants, while Player 2 wears green.
* ConservationOfNinjutsu: Multiple mook ninjas? No problem. One boss ninja? Bigger problem.
* DamnYouMuscleMemory: A to attack and B to jump?!
* DareToBeBadass: "The forces of good have never been so BAD!" claimed one advertisement for the home version.
* DegradedBoss: Kusamochi Karnov and Zombie Animal. Inverted with the third boss, who is literally a BossInMookClothing.
* DistressedDude: The President. Maybe BadassInDistress too, depending on your point of view.
* DoppelgangerSpin: The {{ninja}} boss in the [[DownTheDrain sewer level]].
* DragonsUpTheYinYang: The BigBad is named "[=DragonNinja=]".
* {{Eagleland}}: Bad Dudes saving the President of the US in a game made in Japan. A lighthearted use of the positive version.
* ExcusePlot: Albeit one of ''[[MemeticMutation legendary proportions.]]''
* FightingWithChucks: One of the weapon pickups is a set of nunchucks. It's the best weapon with the longest reach and does double damage compared to the normal punch.
* FingerlessGloves: Part of the tough-as-nails 80's hero aesthetic.
* GuestFighter: VideoGame/{{Karnov}} was actually the star of a previous, more obscure Data East game.
* HighlyVisibleNinja: Blue ninjas, grey ninjas, red ninjas, green ninjas, ''on fire ninjas''.
* HurricaneKick: Pressing jump and attack simultaneously executes this. It makes the player more vulnerable to CollisionDamage, unfortunately.
* KingMook: The green ninja boss in Stage 3.
* ManOnFire: The aptly named Fire Ninjas will light themselves on fire. The only way to kill one of them is to do a spinning kick on their head.
* MarketBasedTitle: Known as ''Dragon Ninja'' in Japan, ''Bad Dudes vs. Dragon Ninja'' for the American arcade release, and then shortened to just ''Bad Dudes'' on the NES.
* {{Mook}}s: The blue ninja mooks are appropriately called "Zako Ninja" in the end credits ("Zako" means mook in Japanese). The red-clad weapon-wielding variants are called "Buki (Weapon) Ninjas", and the black-clad shuriken-throwing ninjas are called "Nage (Throw) Ninjas". There are also Kunoichis, dwarf-sized Mini Ninjas, and helmet-wearing/sword-wielding {{elite mook}}s called Kabutos.
* {{Ninja}}: Ninjas are the main adversaries of the games.
* NoCelebritiesWereHarmed
** The President was changed from Ronald Reagan ("Ronnie") in the arcade version to George H.W. Bush (just "The President") in the NES version.
** One of the bosses is a Road Warrior/Legion of Doom lookalike named "Animal".
* NamedByTheAdaptation:
** The two player characters were nameless in the arcade version. On the NES, they were called Blade and Striker.
** The third boss, a green ninja with a body-splitting technique, is the only boss not named in the arcade game, although all the other ninja enemies are simply referred to as such, but with a moniker identifying their attack patterns (e.g. ''zako ninja'' for the unarmed blue ninja {{mook}}s, ''nage ninja'' for the shuriken throwing ninja, ''buki ninja'' for the armed ninjas). On the Famicom version's manual, he is referred to as Hanzo.
* PaletteSwap: The three basic types of ninja mooks (Zako, Nage, and Buki) are the same sprite with different colors for their outfit (blue, black, and red), while the boss of Stage 3 is a green ninja who can make duplicates of himself. The DegradedBoss versions of Karnov and Animal, Kusamoci Karnov and Zombie Animal, are the same guys with weirder skin colors.
* PowerGlows: You can charge your Dude's punches to make him glow and take out enemies in fewer hits.
* RatedMForManly: Or alternatively: Rated B For Bad(ass).
* SleevesAreForWimps: Another part of the tough-as-nails 80's hero aesthetic.
* TotallyRadical: You can ''smell'' TheEighties radiating off this game.
* TrademarkFavoriteFood: Burgers for the President.
* TraintopBattle: The second level.
-> ''I'M BAD!''
