** ''Series/OhsamaSentaiKingOhger'': The King Ohgers all transform using identical swords called the Ohger Calibers that are activated by triggering the five insect-themed switches on them. The evil ranger Racules transforms into Oh-Kuwagata Ohger using a knockoff version called Ohger Caliber ZERO that has a golden blade and has only one switch one it. This reflects how the King Ohgers are a team of four kings and one wannabe king who work together to protect the five kingdoms, while Oh-Kuwagata Ohger is a self-centered tyrant who wants to rule all five kingdoms. The Ohger Caliber ZERO was actually an unfinished prototype of the Ohger Calibers that Racules took for himself had finished.

* In ''VideoGame/TheLegendOfZeldaSkywardSword'', [[spoiler:the final boss Demise]] wields a sword that looks like a bigger and spikier version of Link's iconic Master Sword. Moreover, both swords are inhabited by spirits that serve the ends of the swords' masters. Whereas the Master Sword's spirit, Fi, mostly just gives advice, [[spoiler:Demise's sword spirit actually serves as his [[TheDragon Dragon]]]].

* Invoked in ''VideoGame/FireEmblemTellius''. The Black Knight has the two blessed swords [[DualWielding dual wielded]] by the legendary warrior Altina, and which are named Alondite and Ragnell. When he confronts Greil looking for a duel he only uses Alondite and actually gives Ragnell to his opponent so it can be an even fight. Greil refuses and ultimately loses. In the aftermath his son, TheHero, Ike takes up Ragnell and duels the Black Knight with it several times to get revenge for Greil's death.

* In the ''Literature/PercyJackson'' series, Luke creates a special sword called Backbiter, which has one blade made of Celestial bronze (which can harm monsters and immortals, but can't harm heroes and mortals) and one blade made out of tempered steel (which can't harm monsters and immortals, but can harm heroes and mortals). This serves as an antithesis to all heroic weapons, which are only forged out of celestial bronze as heroes are never supposed to harm heroes, but more specifically it works as an antithesis to Percy's Riptide.

** The members of the team that [[TropeNamer named]] ThePsychoRangers each used a weapon similar to that of their good counterpart, except for pink, who used a bow and arrow while the good pink used a ray gun resembling a satellite dish. Their weapons had a more organic design and didn't have the ability to combine with each other.
** The members of Bosou Sentai Zokuranger, an earlier [[ThePsychoRangers Psycho Rangers]] team from ''Series/GekisouSentaiCarranger'', each have two different personal weapons, with one being similar to the person weapon of their Carranger counterpart and the other being something completely different. They also have their own team bazooka like the Carrangers, although theirs isn't formed by combining their personal weapons.

** The happens rather literally in ''Series/AvataroSentaiDonbrothers'' with the Ninjarksword, a sentient sword that can manifest a body called Don Murasame that resembles an evil version of Don Momotaro, who uses the Zanglassword. The two swords have a similar design but are colored differently and the Ninjarksword is a SerratedBladeOfPain. The two weapons also have constrasting function. The Zanglassword is made for purifying humans who turned into Hitotsu-ki, while the Ninjarksword is the only weapon that ignores a Juto's immortality, although should it kill an immortal Juto, then the human whose life they stole to gain their immortality will also die.

** Due to the HeroesPreferSwords trope, {{BigBad}}s and other important recurring villains will often be a swordsman with an evil-looking sword contrasting with the rangers' swords. {{Mooks}} and the MonsterOfTheWeek rarely get to use swords.

** Her WeaponOfChoice is one half of a giant pair of scissors [[spoiler: created by her father to cut Life Fibers]]. The other half is wielded by the insane Nui Harime, [[spoiler: the woman who murdered her father while stealing said weapon. Eventually, Ryuko steals it back, and it's alternately used [[DualWielding by Ryuko]] [[GoodAllAlong or Satsuki]].]]

*** This is the motif of Roxas's alternate keychains in ''358/2 Days''. While all of Sora's Keyblades throughout the series are modeled and named after the worlds he visits, Roxas's weapons have Nobody motifs and [[NamesToRunAwayFromVeryFast ominous-sounding names referencing pain and loss and/or light and darkness]]. The only two exceptions to this are the [[WeaponOfChoice Zero Gear]] (which turns Roxas's Keyblade into Oathkeeper, Oathkeeper & Oblivion, or the aforementioned Two Become One) and the [[JokeWeapon Casual Gear]] (an umbrella).

* ''Franchise/{{Pokemon}}''. The player and the rival will take starters from the same lab who are usually their most powerful and reliable Pokémon. Starters are not found in the wild, have above average abilities overall, as well as access to a few unique powerful moves. Some adaptations make a plot point that both TheHero and TheRival's [[WeaponOfChoice 'mon of choice]] were raised together as friends before the two kids pit them against each other. That and the rival always takes the one that has a natural advantage over yours.
