Shoulder-Mounted Jets

Shoulder-Mounted Jets is a Quirk used by High-End, and was presumably stolen from a previous wielder.

Description
This Quirk allows its user to have four retractable jet boosters mounted on their upper back, which grant them speed-boosted flight.

Weaknesses
It seems however that the flight is hard to maneuver with, due to High-End's need to use his Transforming Arms Quirk to support his flight.
