Overclock

Overclock is a Quirk possessed previously by O'Clock and currently by the villain Number 6.

Description
The Quirk seemingly allows the user to accelerate to extreme speeds, to the point that to the user, it looks like nothing is moving. However according to Knuckleduster, the Quirk's true ability is that it stimulates the brain, speeding up the user's perception and thoughts relative to everything else, allowing them to move at a much faster speed than others.

In normal situations, the user can move at speeds approximately three to ten times faster than normal. In emergency situations, when the user's fight or flight response is active, the user can move at speeds a few dozen times faster than normal, and can even move so fast that the world seems completely frozen.

The Quirk also grants the user heightened senses, allowing them to see, hear, and think at hyper speed.. They're able to clearly hear words that have been sped up to three-hundred times normal speed when the Quirk is active.

Weaknesses
This Quirk has several drawbacks. It has a cool down period between uses, and can only be used for a few seconds at most. Additionally, if the user is intensely focused on something, the user experiences "brain drain", which reduces the amount of time they can actively use the Quirk. Also, Knuckleduster states that if the user is too focused while using the Quirk, they run the risk of depriving their brain of oxygen.
