THE WORLD

THE WORLD is an INFINITY STANDO, resembling a green gem-like stone. THE WORLD is currently inside of THANOS' INFINITY GAUNTLET. Upon activation, THE WORLD appears as a two-dimensional cracked glass silhouette behind THANOS. 
THE WORLD's power is its ability to stop time, allowing only itself, THANOS and anyone with similar powers, to act within the duration of stopped time. THE WORLD's maximum time stop -- (as of ARC III) is ten seconds. 
THE WORLD's absolute effective range is ten meters, while other entities between ten and thirty meters are either nearly frozen or slightly slower, depending on how far they are.
THE WORLD has an initial cooldown of about thirty seconds, but with the potential it wields, the cooldown could further decrease with more use. 
While it is noted that THE WORLD has a thirty second cooldown, THANOS has attained a more lightweight variant ability of THE WORLD that involves 'mini-skipping'. Mini-skipping stops time for only a split second, but has a split second cooldown as a result.
In the stopped time, THANOS can move his own body freely along with any object he touches that he wishes to move, allowing him to strike his defenseless enemies, move to a superior position, and toy with his victims. All force applied by THANOS during the time stop continues to exist after the time stop. This is seen when the objects that THANOS throws can momentarily move during the stopped time before grinding to a halt.
It is notable that THANOS needs to consciously activate THE WORLD, which means that surprise attacks can prevent him from stopping time.
