Who is built IRL?

Built IRL, a YouTuber whose real name is JT, created a grappling gun for which the word “impressive” would be a severe understatement (h/t The Verge).

What is a grappling hook?

A grappling hook has 3-4 (or more) hooks on it that grab on to ledges and have a rope leading from the back end for people to climb up. The hooks can be thrown by hand, and if they were ever used by ninjas or anyone really, even in modern times, they would be spun around and thrown.

How did Batman get the grappling gun?

In the later Batman #458, a gadget was used off-panel to fire a rope for Batman to swing on. These two appearances are widely considered the first appearances of the grappling gun in the comics. In addition to the pully mechanisms, they were used to create ropes that Batman would use to swing between rooftops.
