I wanted to know her power limitations and here they are:
Strength: 100 tons MAX along with the invulnerability---it only lasts a min before requiring a 15 sec recharge but it's better than nothing.
How high can she jump? 400 ft, equal to 120 meters. She jumps off at a speed of 110 mph.
Because she has the ability to fly at the speed her body moves, her max speed wiyhout any outside help would be flying at 110 mph. Fast enough to kill her if she hit something while her 15 sec recharge was in effect. Not so fast that the speed alone would kill her though. She would definitely wear some type of eyewear to protect her eyes, because her flight speed is static, it won't change unless she stops flying and restarts at a lower or faster speed as she drops.
Because she has other abilities, and the strength/invulnerability is the only one that requires a recharge, she should be able to take on most or all street levelers wth ease.
