A character lets go of the Jetpack he/she is wearing as a desperate or cunning attack against enemies. Given the combustible contents of the jetpack, it can become an effective explosive weapon if not a powerful projectile, or a distracting explosion. Alternatives include a detachable fuel tank of a vehicle.
Compare with Weaponized Exhaust, which weaponizes the jetpack without losing it, Ramming Always Works, which is about running a vehicle into a target (usually another vehicle) to damage or destroy it, and Outfit Decoy, which is about distracting enemies by taking off an article of clothing.
Also see Made of Explodium, in case you were wondering why the jetpack explodes on contact instead of simply making a very large dent in whatever it hit, and Suicide Attack, if the character is killed while still wearing the jetpack in the attack. Riding the Bomb may be the inverse of this trope.
Examples:Anime and Manga
- Mobile Suit Gundam Thunderbolt: In the anime, Io ejects one of the Full Armor Gundam's propellant tanks to create a fake explosion to initially fool The Living Dead Division into thinking it was destroyed. Later, Io lodges the other propellant tank on a Zaku to send it flying ahead of him, then launching a missile at the tank to cause a huge explosion.
- Mobile Suit Gundam Unicorn: Banagher piloting the Full Armor Unicorn Gundam launches one of its giant propellant tanks at a Neo Zeon mobile suit to assist Conroy piloting the Jegan ECOAS.
- DARLING in the FRANXX: The second Gutenberg-Class is defeated when Goro uses one of Delphinium's spare battery pack as an explosive and detonates it from the inside.
- Godzilla Against Mechagodzilla: When Mechagodzilla's jetpack gets its gun attachments blown off, it fires the rest of it off at Godzilla to knock him down. Something similar happens in the sequel when Mechagodzilla fires his Shoulder Cannons at Godzilla except they detonate this time.
- Pacific Rim: Uprising: Jake repurposes one of Scrapper's two vital ion cells into an impromptu EMP grenade to fight off November Ajax. It works ... for about ten seconds. Cue Ajax' One-Hit KO against poor little Scrapper, on top of the latter running out of power from losing of the ion cells.
- In Hogs of War, the jetpack works like this - it can be jettisoned in mid-air, dropping it like a bomb below and allowing the pig who was using it to float to safety on a parachute.
- D.Va in Overwatch has her ultimate attack, in which she rigs her jet-propelled mecha suit to self-destruct and "drops" it with all momentum being applied. It deals 1000 damage to anything in range when not blocked by a shield, and is often used to clear away points of interest, such as control points or payloads.
- In Grossology, in the episode "Fartzilla", Fartor is causing chaos in Fartzilla, a Humongous Mecha dinosaur powered by farts. Ty realizes that farts are composed of combustible methane and launches his jetpack straight into the exhaust, causing the methane to set alight and sends the mecha blasting off into the atmosphere.
