"With Our Swords" Scene

The Big Bad has succeeded in his goal of stealing the Crystal of Unstoppableness! Soon he will be unstoppable! And to make things worse, all the heroes have been wounded and are unable to fight... except for John Q. Protagonist.

"Mighty Glacier: "Take my shield. You know how tough it is. It's not doing me much good right now anyway."

The Rival: "Hmmph. I'll let you borrow my Sword of Eternity, but you're giving it back right after this is over."

The Chick: "Please, John, just take my Amulet of Hope. Be careful.""

The main character then goes on to kick a ton of bad guy ass using all of the items he received. This can be done with a single character who lends him a weapon, in which case it is usually The Rival. Usually reserved for the Final Battle.

Occasionally this will happen in a series with modular robots, in which case the other heroes (or their vehicles) lend their leader parts of their bodies (not to be confused with the entire robots combining).

Anime and Manga

 * Medabots has a scene where Metabee has been badly damaged, so he borrows Sumilidon's super-fast legs, and the Arm Cannons of Crosserdog and that guy who looks like Metabee. You know the one.
 * Gaiking: Legend of Daiku-Maryu: Gaiking's cockpit combines with the arms of Raiking and the legs of Vulking to form the ludicrously powerful "Gaiking the Great".

 * Used in Yu-Gi-Oh! 5D's: Yusei's in jail and the arrogant warden tells him he can duel his way out - of course, his deck was confiscated when they're arrested. But all of the prisoners have smuggled in a card or two with special meaning to them, so they loan them all to Yusei, giving him enough to make a usable deck to take the warden down a few pegs.
 * Note that this is before Yusei's duelling style is derailed into "I summon Stardust Dragon".
 * This happens again before the final battle with Z-ONE, where the other members of Team 5D's lend Yusei their Signer Dragons. He ends up using them all to perform an Over Limit Accel Synchro, summoning Shooting Quasar Dragon.
 * Saint Seiya has the fight between Seiya and Ikki. After his friends are knocked out, Seiya is forced to fight alone and is systematically helped by Shiryu's Dragon Shield and Shun's Andromeda Chain.

 * In Farscape, John is the only one of the crew who isn't too incapacitated by an alien who altered the bioluminescence on Moya (due to his comparatively poor eyesight). The rest of the crew each give him something to prepare himself for a confrontation with the alien--including D'argo giving him his sword--which leads to him posing like a knight.
 * I'd swear that when I first saw that episode, as Crichton posed he declared, "Behold, Sir Crichton the Ridiculous!" It's not on the DVDs though, so I must have imagined it.
 * It was in a gag-reel.
 * Done literally in Kaizoku Sentai Gokaiger, with four of the Rangers handing their swords to Gokai Blue. Yes folks, one guy with FIVE swords.
 * Later on, Gokai Green tries to build a new weapon but runs out of spare parts. He eventually works up the nerve to ask the rest of his team for their weapons to disassemble, which they give without hesitation.

 * In the same show, second to last episode this troper believes, Kaito finally gives Decade the Diend card so they can win a battle.

Video Games

 * In Mega Man X, if you haven't gotten the arm cannon upgrade, Zero will give X his arm cannon (which has the upgrade) just before he dies in Sigma's castle. In X3, he'll do it again; if you use him to fight a particular midboss in Sigma's fortress, he'll die after defeating it, but not before giving X his Z-Saber.
 * A variation in Final Fantasy IX. Much of the story is about the characters' finding their purpose or reason for fighting.  a Hopeless Boss Fight sees your entire party defeated. Whichever four party members are inactive share their reason for fighting or the meaning the have found in their journey together, each reviving one of the active party members for the boss fight that immediately follows.
