This series features examples of:

  • Affectionate Parody: of most other fighting games at the time.
  • Big Bad: Each game in this series has its final boss:
    • Power Instinct: Oume Goketsuji
    • Power Instinct 2: Otane Goketsuji
    • Gogetsuji Legends: Chuck
    • Groove On Fight: Bristol-D note 
    • Matrimelee: Princess Sissy
    • Bonnou no Kaihou: Bobby Strong
    • Matsuri Senzo Kuyou: Shinjuro Goketsuji
  • Big Screwed-Up Family: Every playable character in the series and a number of the non-playables are members of the Goketsuji family. Some more distant than others, of course...
  • Bishōnen: Several, most interestingly Prince's alternate form.
  • Crossover: The guest fighters from Rage Of The Dragons appeared in Matrimelee. On the other hand, Kurara appeared in a Virtua Fighter-esque PlayStation game, Heaven's Gate.
  • Darker and Edgier: Groove On Fight.
  • Energy Absorption: The Otane, Oume, Elizabeth, and Sandra do this in order to transform into their younger selves.
  • Expies:
  • Fan Nickname: Legends and Matrimelee were called Gogetsuji Legends and just Matrimelee in the US, but most fans use the Power Instinct prefix when referring to them for the sake of consistency.
    • The blue-ish aura that surrounds a character when they gain a level in their power bar is called "Stress Flame" by fans because said power bar is known as the "Stress Meter". Since Legends, every character (or almost everyone) has one or two special moves that become stronger if performed while dashing or right after a dashing attack, those have been nicknamed "Shadow Attacks".
  • Goketsuji Publicity: Otane and Oume themselves.
  • Gonk: Prince.
  • Green Oni, Blue Oni: The Kuno brothers Shintaro and Buntaro.
  • Guest Fighter: Jimmy, Lynn, Elias, and Mr. Jones in Matrimelee.
    • So did Bobby Strong in the PlayStation 2 semi-sequel Bonnou no Kaihou, though the ROTD characters did not return, sadly.
  • Kid Appeal Characters: Kintaro Kokuin, Kurara Hananokōji, Popura Hananokōji note , and Takumi Hattori.
  • Limit Break: A few characters in Matrimelee and up had a level 3 Forbidden super move.
  • Lohengrin and Mendelssohn: Whoever defeats Sissy in Matrimelee will proceed to marry her... NOT!
  • Look what Matrimelee did to some of the characters' names:
    • Annie -> Anny
    • Kurara -> Clara
    • Kuroko (non-player character)  -> Enabler
    • Otane Gōketsuji -> Tane
    • Oume Gōketsuji -> Ume
    • Thin Nen -> Chinnen
      • On a similar note, Oshima is spelled Osima in Power Instinct 2.
  • Mana Meter: Introduced in Power Instinct 2. Getting hit or striking a blocking opponent builds this up. Groove On Fight introduced multiple levels of the meter, which shows up in later games.
  • Meaningful Name: Groove On Fight utilizes background dance music.
    • On the subject of acronyms, Max Ax Dax in Groove On Fight was better known as M.A.D.
  • Older Than They Look: See Energy Absorption.
  • Only One Name: Chuck, Falco, M.A.D. (subverted; his name is Max Ax Dax), and Marutanote 
    • There's a related the unlockable music video for it for it: onmyoji Yabeno Hikomaro, shrine maiden Kotohime, and three backup monks (referred to only as the Bozu Dancers) dance in the background to a surprisingly catchy tune. The song and video became something of a meme.
  • Rule of Three: Strangely enough, each character in Groove On Fight has a three-pieced special move.
  • Shoto Clone: Reiji and Keith, more or less. In Groove On Fight, it's Larry and Chris. Annie also qualifies.
  • Source Music: The background musicians are usually visible in each stage.
  • SNK Boss: Bristol D. and Princess Sissy. Especially Sissy.
  • Taunt Button: Matrimelee introduced this. In case both players taunt at the same time, they must proceed to a "Bloodline Battle", where they'll press a correct button to respect each other until either fighter makes the wrong move.
  • Tomboy and Girly Girl: Angela (Butch Lesbian) and Annie (Lady of War).
  • Transformation Trinkets: Shown in the Gogetsuji Legends intro are Clara's wand and Kinta's bib, which respectively turn them into Super Clara and Poochy.
  • Widget Series
  • X Meets Y: Groove On Fight is Street Fighter Alpha meets Kizuna Encounter with a touch of Street Fighter III and Mark of The Wolves.
