Kunio-Kun/YMMV


 * Crowning Music of Awesome: So, so much.
 * The "Running Around The Streets" theme of River City Ransom, a major Ear Worm and very long tune by NES standards.
 * Almost the whole soundtrack of Kunio Tachi No Banka.
 * "Lover to Friend" as heard in the CD that came with one of the games.
 * Despite not technically being part of the canon, Target Renegade, an American sequel made specifically to the American version of Nekketsu Kouha Kunio Kun, earns a mention just because it's so cool.
 * Germans Love David Hasselhoff: The Polished Port of Renegade for the ZX Spectrum was a smash hit in the European home computer market, particularly in the United Kingdom. So much that it spawned two sequels exclusively for that market, one of which is universally considered an Even Better Sequel!
 * Memetic Mutation: "Barf!"
 * Ditto, the scene of River City Ransom with the sauna.
 * Sequelitis: It is said that Technos Japan's over-reliance on the Kunio-kun series, at the expense of their other franchises is what eventually drove the company out of business.
 * That is to say, the games themselves play perfectly fine, and as the series went on, were just refinement upon refinement on both the Beat Em Up genre as well as fun as hell party games for the sports spin offs. But Technos could have used some variety under their belt.
 * That One Boss: Even though he's the Final Boss, Sabu from Nekketsu Kouha Kunio Kun, better known as Renegade in the west, is this for one reason: his gun is a One-Hit Kill.
 * Uncanny Valley: A common gripe expressed by many fans about the two newest Kunio games released on the Nintendo DS. These games moved the series into the third dimension, and there's ample evidence they made an attempt to preserve the Super-Deformed, blocky proportions of their sprite counterparts, but a very unfortunate sacrifice was still made in the form of the facial expressions, which used to be surprisingly dynamic (and often funny) for such a distinct-looking series, and because limbs often cave into torsos and change size, distinct features are often obscured. To be fair, the games look a great deal better in motion, and the developers actually capitalized upon the 3-D engine by designing courses that utilize it creatively, but it still is a sad compromise.
 * Fortunately, the Nintendo DS is approaching the end of its lifestyle, and its successor is much more powerful, so Kunio games in the future stand to look much better.
 * Interestingly, the 3DS and PS3 instalments of the series mostly retain the old 2D sprites designs (with an added animation base or two here and there), placing them into 3D environments.
