A franchise using nineteen movies to build up an item gets a "wow" factor.

Marvel’s Infinity Gauntlet follows this pattern. The glove holds six Infinity Stones, each powerful alone. Together, they let the wearer achieve any wish with a finger snap.

Earth's Mightiest Heroes face Thanos first. Thanos uses the Gauntlet to snap 50% of life in the universe. Our heroes lose the battle. They win the war using the Stones again. They snap all life back and eliminate Thanos and his army.

The Men in Black (MIB) division hides, monitors, and protects humanity from aliens. They use sophisticated gear. Will Smith’s Agent J gets a small device; he states, “I feel like I'm gonna break this damn thing!”

This constant theme runs through Men in Black.Men in BlackAgent J and the audience realize the universe or galaxy looks deceptive. The recoil from the innocent-looking noisy cricket sends him flying through a car’s windshield. Thankfully, it hurts whomever you are aiming at.

The mobile division uses this primarily.Starship TroopersThe tactical oxygen nuke wipes out multiple targets. It acts like a travel-sized nuke. Set to detonate, it loads into a rocket launcher, though it can also function like a grenade.

Though the pulse rifle has many versions since its start, the first appearance in James Cameron’s film remains the most memorable.AliensThe first *Aliens* installment began.AlienThe first *Alien* saw a crew fight the cold-blooded, acid-blooded Xenomorph, leaving only Ripley alive. In *Aliens*, Ripley faces many more aliens, but the United States Colonial Marine Corps and their firepower level the field.AliensAliens features more aliens Ripley must confront. However, the United States Colonial Marine Corps and their firepower balance the situation.

The Marines use the pulse rifle as their main weapon. Cpl. Hicks describes it best.

The movie shows the BFG emits a large, blue plasma blast that obliterates targets and burns the area, not the full damage on a living target, despite its futuristic rifle look and black finish.

Making its first appearance inPredator 2The smart disc is featured. Beings from an alien race bred for hunting created it, giving them weapons like a huge spear and an invisibility cloak. The smart disc remains supreme; it always returns to its owner, like a miniature, fatal Captain America shield.

The smart disc cuts through anything it touches. The Predator’s wrist device can change its flight pattern and size once it is released.

The Matrix weaponry feels smooth and slick. The real world does not share that quality. This weapon is a lightning rifle. It has a monitor with basic targeting, needing two hands to operate. This is not a travel item; it is not.

Its creation served one specific purpose: a last resort if a human got close to a machine race sentinel. One or two lightning bolt blasts take down the enemy. Although not its main job, it harms human targets the same way. The double-crossing Cypher shows this in The Matrix.

The Arc Gun, also called the “Mulcher,” lives up to its name. It heats the enemy, causing them to burst into mulch. You might not get a direct blast, but you will still sustain a fatal injury.

The suit requires extensive training before use. It also runs on a battery. If the power dies, the battery must be replaced. Otherwise, the wearer becomes stuck inside the suit.

The Doctor, a lord of time and space, traveled thousands of universes in his TARDIS. The sonic screwdriver, like the Doctor(s), has had many versions. It began as a tool, but now it does much more than pick locks.

The sonic screwdriver scans, fries circuits, and disables enemy weapons. It can also fire a sonic blast strong enough to destroy a Dalek. Doctors use it for defense often.

The phaser is a standard firearm for almost all Starfleet members. Many adaptations changed its function. Its original settings let the owner stun, heat, kill, or disintegrate living things. The range lets it target a single spot or a wider area.

This scene shows an unforgettable cinema transition. The lead hominid throws his new tool up, and the shot cuts to a satellite falling back down, making the metaphor clear.

The 'Sick Stick' is the main non-lethal tool for future law enforcement inMinority Report.

This device looks like a baton. Its use technique resembles a hand-held taser. This device does not just shock or stun targets. Instead, it causes immediate vomiting upon contact. Officers face danger if this device falls into the wrong hands.
