* AdaptationDisplacement: {{Reformulated Game}}s, especially the NES version, are the most popular versions of the first game.
* BreatherBoss: Feedle is (are?) ridiculously simple compared to the opponents before and after him (them?).
* FirstInstallmentWins: The second game was less popular due to being exclusive to rare gaming platforms.
* GermansLoveDavidHasselhoff: The NES version is very popular among Chinese gamers to the point it's included in virtually any Famiclone carts available there.
* GoddamnedBats: The mooks in second game. Those mooks respawn infinitely, and they move so fast that you must evade them very precisely.
** Also, [[ShockAndAwe Li Jen's thunder attacks]] are fast. The player must evade them quickly to avoid getting hit.
* HilariousInHindsight: Mei Ling is a boss in the second game. Guess who shows up as a MissionControl in ''VideoGame/MetalGearSolid'' sharing the same name?
* OlderThanTheyThink: As far as Fighting Games go, this game precedes the very first ''[[VideoGame/StreetFighterI Street Fighter]]'' game by two years, and has established things for the genre before that game and its [[SequelDisplacement much more recognizable]] [[VideoGame/StreetFighterII sequel]].
* ThatOneBoss: Club, who not only deals a lot of damage with his eponymous weapon, but he also carries a shield, allowing him to block attacks.
** Li Jen in the second game. See GoddamnedBats above.
