The Mobile Fortress Destroyer (機(き)動(どう)要(よう)塞(さい)デストロイヤー) was a man-made, fast-moving, fortress-class weapon shaped like a gigantic spider that was built by the technologically advanced civilization Noise.

Overview

The Destroyer looks and moves like an enormous eight-legged spider. It has many "eyes" on the head region that act as sensors. It also has golems on its legs and back carapace, for ground and air offense/defense. Although not visible, it also has a strong magic barrier that will negate any incoming magical attacks.

Since it is non-living weapon, it has no personality. Originally, people thought the operators went crazy and lusted for destruction. The Axel adventurers later found out the machine has been fully automated for centuries, and the only human who piloted it had passed away long ago. Although its inventor was not "crazy", he was undoubtedly one of the biggest idiots ever. He built the Destroyer and set it to rampage mode by accident when drunk, but he had no way to stop it or even get off.

History

The inventor of the Mobile Fortress Destroyer was a NEET from Japan, who initially had laudable objectives to defeat the Devil King, but later reverted back to his licentious and sordid comportment. The only reason the inventor made the Destroyer was to avoid a possible execution sentence; despite how his invention later turned into a cataclysm that started off with destroying Noise, the inventor was apparently very satisfied at the results, and spent his remaining days aboard the rampaging fortress.

In the following centuries, the Destroyer roamed the continent, flattening cities and towns in its path as well as ravaging the natural environment. After countless attempts to stop it failed, people were forced to treat it like a natural disaster, evacuating targeted settlements beforehand and rebuilding from the ruins afterwards.

However, when the Destroyer headed towards Axel, following Kazuma's strategy the local adventurers took a stand outside the city's walls, during which Aqua broke the Destroyer's magic barrier so that Megumin and Wiz could blast the legs off the fortress and make it crash-land. After the Destroyer's self-detonation sequence was set off, the adventurers stormed inside in an attempt to stop it, ending with the coronatite core used as power source getting teleported away at Kazuma's direction, and the Destroyer itself blown to pieces by Megumin before it could explode from overheating.

Variations

• Mass-Production Type Destroyer (量産型デストロイヤー): Scaled-down versions of the Destroyer left in the deeper levels of the Underground Research Facility Ruins.
• Prototype Destroyer (プロトタイプデストロイヤー): Scaled-down test version of the Destroyer left in the deeper levels of the Underground Research Facility Ruins.
• Destroyer Flight-Test Type (デストロイヤー飛行試験型): Scaled-down flying versions of the Destroyer roaming the air above the Island in the Sky.
• Dimensional Fortress Destroyer (次元要塞デストロイヤー): A scaled-down version of the Destroyer created for the purpose of letting its creator meet his favourite fictional characters, and is capable of blasting open doorways to other worlds, like the A Certain Scientific Railgun world.

Abilities

• Hardened but light-weight magical plates: Protects its surface from most of conventional attacks and ordinary wear-and-tear, while allowing high mobility despite its size. The high physical defense allows the Destroyer to flatten towns and terrains without getting any scratches.
• Powerful magic barrier: Surrounds the entire fortress and repels any incoming magical attacks.
• Automated golem army: It has stationary golems on the back carapace to fire against incoming air targets, stationary turrets on the legs against ground targets, and golem defenders inside against any invaders.
• Eight armoured legs: Allows the fortress to move quickly across any terrain types.
• Advanced programming: Allows it to jump over obstacles and thoroughly flatten any targeted town in its path. However, it does not distinguish human towns from demon towns.
• Self-destruct sequence: Initiates when it gets heavily damaged.
• Legendary Coronatite power source: It can operate pretty much indefinitely.
• Scatter grenades: Fired by the scaled-down versions of the Destroyer for taking out multiple intruders at once.
• Jamming wave: Emitted by the scaled-down versions of the Destroyer to prevent intruders from casting magic.
• Jet engines: Allow the scaled-down flying versions of the Destroyer to float and propel themselves through the air.

Trivia

• The inventor used the blank design paper to swat a spider and turned it in as is. However, the higher-ups loved his spider smudge "design" and even complemented him on the details and realism.
• Magic Keyholders in the form of miniature toy Destroyers that are magically animated had become popular among children, who pitch them against one another much like with stag beetles. Many variations of these exist, including Lovely and Secret Oni, which comes with a self-detonation ability.
• Before the Destroyer was completed, the Head Researcher created a premier miniature of the mobile fortress, though he later stashed it among his other creations in the Crimson Demon Village's underground warehouse. The miniature is usually kept within a glass case, since being touched by somebody bearing magical power will activate it, resulting in activity ranging from it running around to self-detonating.
• The Destroyer ranked the 17th place in KonoSuba Popularity Poll.
