Inquisitor

From Doom Wiki

The player fights one of the giant and intimidating Inquisitor robots in the Loremaster's Lab.

An Inquisitor glides gently to the ground on a rocket booster to confront the player.

The Inquisitor is the most powerful non-boss enemy in the game Strife. It is a gigantic bipedal robot which appears much similar to many different varieties of popular mechs, and to an extent resembles a larger version of the Reaver. It has no visible head, except for a blocky structure where it would be. It is equipped with rocket boosters on its back and feet, allowing it to take flight temporarilly to get over walls between it and the player. It is the only bad guy in a Doom engine game that that can switch between walking and flying.

The Inquisitors are extremely well armored, with 1000 Hit Points, and equipped with a grenade launcher and a Mauler blaster in addition to it's extreme mobility.

The Inquisitor only appears in the final third of the game. A couple guard the Loremaster in his laboratory and a few also appear in the Entity's spaceship wreck at the end of the game.
