Scrappers are enemies in Phoenotopia and its remake, encountered at the very end of the game. They're a group of high-tech robots designed to protect the Phoenix Lab from invaders.
Phoenotopia
Scrapper Sentry
Scrapper Sentries are the first type of Scrapper encountered in the game. They appear in the Ancient Crater as a secondary defense system against intruders in case the Ancient Sentry Towers couldn't stop them. Scrapper Sentries are turrets that appear on floors and ceiling and periodically fire shots at Gale. They're fairly durable, but two charge attacks can take them out easily.
Scrapper Drone
Scrapper Drones are basically mobile versions of Scrapper Sentries that only appear within the Phoenix Lab. They fly towards Gale in short bursts of flight and shoot when they're not moving. Scrapper Drones can be hard to hit because they fly away from Gale when she gets close to them, but they can be knocked out of the air with any projectile. For this reason, the easiest way to deal with a Scrapper Drone is to hit it with a shot from the Slingshot. After it falls on the ground, you can go up and mash the attack button until the drone is destroyed.
Scrapper Globe
Scrapper Globes are the rarest variety, only seen during the battle with the Computer Guardian. The Computer Guardian always spawns four Scrapper Globes (six when its health is low) for its first attack. The Scrapper Globes bounce across the floor for a few seconds before releasing chains to attach themselves to the floor and ceiling. The Globes then ride along these chains and occasionally release electric sawblades that run down the chains and across the floor. They're the weakest type of Scrapper and can be destroyed in one hit with your melee weapon, although it's recommended to use the Javelin on the ones that are too high for Gale to reach.
Phoenotopia Awakening
All three Scrapper enemies will be returning in the remake, with new graphics and names.
