Oshitsu Osarettsu (オシツオサレッツ) is an enemy from Mega Man 10 that blocks the path with a large shield and try to push enemies. They can be pushed with attacks. They appear in Nitro Man's stage, Wily Castle 2 and Special Stage 1. In Hard Mode, they also appear in the stages of Chill Man and Solar Man. In Easy Mode, they're pushed back much further than shot. In hard mode, they move much faster. The best weapon to use is the Solar Blaze, as it will go through its defence.
- Its name is derived from the Japanese phrase "oshitsu osaretsu", which roughly means "to push and be pushed".
