The Hero's Weapon

The weapon of choice (or "choice") the Hero has with them on their adventure. Different Heroes have different times when they first get their weapon. Some have it from before the Call To Action, others have it handed down to them from a previous Hero, and some pick it up shortly after their travels begin. Depending on the type of franchise and its genre, the Weapon can wildly vary in type, build, and power, but the general rule of the Weapon is that it is strong enough to take down powerful foes, but it isn't too incredibly useful. It also cannot be any stronger than the Hero's current foe's and has to be much weaker than the Villain's to prevent any quick fixes in the story. If it's a magic-based weapon, it can't warp its user too far if it has the Teleportation superpower, can't Ctrl + Z anyone or anything, and can't grant the Hero the Invincibility superpower when they wield it. To maintain the power balance, the Weapon needs a finite amount of ammunition if it's a gun, bow, or any other ranged weapon.
