YMMV / TwinBee

• Adaptation Displacement: Like in the case of Contra, the first Famicom TwinBee game is what most people not from the U.S. think of when they hear about the franchise even though it's an arcade port. For the U.S. where the first game was never exported, it's instead Stinger that most Americans remember.
• Anti-Climax Boss: The final boss of Detana!! TwinBee goes down very easily.
• Best Known for the Fanservice: The anime is perhaps best known for the beauty pageant scene, where Dr. Mardock accidentally enlarges some of the contestants with a growth ray.
• Ensemble Dark Horse: Pastel and Winbee, ordinarily the second player, have proven much more popular than Light and Twinbee (the first player). The duo often cameos with Shiori Fujisaki in multiple Konami games and are playable in Konami Krazy Racers, Bombergirl and Live Powerful Pro Baseball Mobile.
• Game-Breaker: In "Rainbow Bell Adventures", Winbee and Gwinbee can both qualify as this.
  • Winbee has a very short jump meter that allows her to blast through levels incredibly quickly, but she also has a long attack meter that makes bosses hard to defeat.
  • On the other hand, while Gwinbee's long jump meter makes platforming a bit trickier, the short attack meter makes almost every boss in the game an absolute cakewalk.
• Hilarious in Hindsight:
  • Light's voice actor is Kappei Yamaguchi. Fast forward to 2006, and the same Kappei Yamaguchi ends up voicing L, who is pitted against an evil guy named Light.
  • The Tokimeki PokéLive! and TwinBee counterpart of Pastel has Cerise as her surname. A few years after PokéLive!Pastel's debut, in 2020, A Professor from Vermilion City in Pokémon Journeys: The Series shares the same surname as that version of Pastel.
• Memetic Badass: Gwinbee in "Rainbow Bell Adventures" for being incredibly powerful against bosses despite only being a year old.
• Scrappy Mechanic: The original arcade TwinBee game runs on Bubble Memory, an early attempt at solid-state memory. The problem is, it needs 99 seconds to warm up the system to its operating temperature, and it's prone to electromagnetic interference, which is inevitable in a public arcade with many other functioning cabinets present. As a result, working TwinBee boards are quite rare.
• Sequel Difficulty Drop: As Konami made more sequels of TwinBee, the newer games' difficulty dropped partly because they got a more robust array of bonus items, special abilities, game balance tweaks, and anti-frustration features. For example, the MSX version of the first game had a black bell power-down that kills your ship upon contact. In future installments like Detana!! TwinBee, the black bell decreases the ship's speed by one level instead.
• Sequel Displacement: Detana!! Twinbee pretty much established the tone of the rest of the series thanks to the contribution of anime character designer Shuzilow HA, who was heavily involved in the game's story and characters.
• That One Boss: Almost all of the bosses in "Rainbow Bell Adventures" can be very difficult due to their large health bars, but Delnbee is probably the absolute worst. Since this boss is constantly moving, it can be very difficult to take the time to slowly charge up a fireball. The only other move that takes out a large chunk of his health is the dash, which you'll have to aim near perfectly or else you'll run into him right when you become vulnerable again and lose a heart. Oh, and every time you deal damage to Delnbee, he starts throwing mechanical parts around that are very hard to avoid.
