Time Travel is the ability in which an individual or object literally moves through different points in time. There are various methods of achieving time travel. One of the most well known is through the use of a Time Stone. Silver the Hedgehog, a frequent time traveller, uses one of these stones to initiate Chronos Control. (SU: #8) Warp Rings have also been shown to be capable of time travel, which Silver previously used upon his very first trip into the past, before being granted a Time Stone. (StH: #195, #196)
