Hook is massive, rope adds a lot of drag, so the launcher's power (and recoil) should be considerable. As in "pneumatic Grenade Launcher of load-bearing design with built-in reel of strong rope" - though strong crossbow could work too. Grappling guns actually exist (see " Real Life" below), but the real ones are somewhat larger than depicted on screen, especially if not base-fired only (though recent designs allow more compact systems). It's also very handy when you find yourself or an innocent civilian falling, but let's hope the cord has some elasticity.

If the cord can automatically retract, the person can just hold on with one hand with inhuman strength to get pulled up this is especially dramatic if they're holding someone else with their other arm. The wrap-around cable is a strange effect, as it always attaches to the anchor point snugly enough to support whatever is on the other end of the cable on the first try. The hooks themselves are Plot-Sensitive Items, capable of all three variants of Instant Knots - latching onto, wrapping the cable around, or piercing their target, depending on the needs of the script. but it generally conveniently appears from hammerspace when it is needed. Its limited utility makes it a special-purpose item that the hero is unlikely to carry. The Grappling-Hook Pistol is generally a fairly bulky item for a handheld pistol, though unreasonably small for the length of line and hook firing charge that it contains.

While it can be an arrow with a grappling hook more often it's just a standard arrow with a rope tied to it. In settings that predate firearms the alternative is the grappling arrow used by bow wielding protagonists.

It also lends itself to You Will Not Evade Me when shot directly at someone. It can also be used to implement the Building Swing, though its primary function is usually just for climbing. Particularly spiffy examples are equipped with motors, and can function as field-expedient elevators as their users hold on for dear life. This handy bit of Applied Phlebotinum can deploy a grappling hook with laser-guided precision to a secure holding point at the top of any tall building, allowing its user to climb with ease. The Grappling-Hook Pistol is an essential item for any aspiring Badass Normal, Cape, or secret agent.
