The Time Stones (タイム·ストーンズ Taimu Sutōnzu?) are objects that appear in Sonic the Hedgehog CD. They are seven gemstones that lie dormant on the satellite Little Planet which orbits Earth and have the power to change or manipulate time. In the game, they can be obtained from Special Stages, much like the Chaos Emeralds in most games.


The seven Time Stones are colored red, orange, yellow, green, blue, purple and cyan. When used, they have the power to control time itself and let their wielder move through the passage of time. It is also said they can cause an event of miracles to occur, like transforming polluted water and the surrounding desert into a beautiful lake.[1]


The origin of Time Stones has not been explicitly stated other than that they are found on Little Planet. The satellite, along with the Time Stones, are able to move through time, which is why Little Planet only appears in the earth's atmosphere for one month every year above Never Lake.[1]

In Sonic the Hedgehog CD, Dr. Eggman attempts to collect the Time Stones in order to take over Little Planet and the rest of the world. Sonic tries to stop his plans by finding them first.[1][2]

In the game, Time Stones can be collected from seven different Special Stages. In order to enter a Special Stage, the player has to hold fifty or more Rings and jump into the Giant Ring at the end of a Zone. In a Special Stage, the player has to destroy all the UFOs to get a Time Stone. Collecting all the Time Stones unlocks the good ending of the game. In addition, anytime the player travels to the future in a Zone, they will always get the good future, meaning they can enjoy a beautiful landscape and not face any Badniks.

In the good ending of the game, Sonic finally defeats Eggman in Metallic Madness and frees Little Planet from Eggman's control as it leaves earth with the Time Stones. However in the bad ending, Eggman nabbed one of the Time Stones as he escapes from Little planet.

In the Sonic the Comic series published by Fleetway Editions, there are only six Tine Stones rather than seven (at the time, the series also included only six Chaos Emeralds). Their appearance was also somewhat inconsistent as they were both presented as gemstones and regular-looking oval rocks.

Hidden on the Miracle Planet, Dr. Robotnik eventually found a Time Stone and used it to cyberform all of Miracle Planet. As a part of a bizarre time paradox however, Sonic was able to use a Time Stone to undo Robotnik's work by changing history.

In the Sonic the Hedgehog comic book and its spin-offs, the Time Stones and their background borrow elements from both the games and the Sonic the Hedgehog animated series. In this media, the Time Stones are hosted on the Little Planet, where they are rumored to be protected by Nicholas O'Tyme or the Knights of Kronos. One of them is used by Silver the Hedgehog and Mammoth Mogul to travel through time.


  • Time Stones in Sonic the Hedgehog CD have varying appearances through the game. In Special Stages and the ending cinematic, they appear to be milled amethysts with six sides but in the result screen after completing a Special Stage, they are seen having eight sides to look similar to the Chaos Emeralds from earlier 16-bit installments.

  • Time Stones' similarity to the Chaos Emeralds is striking, in appearance as well as their ability to manipulate time and space. The only major change being that Time Stones are shown to be much larger, as Sonic grabs them after completing a Special Stage.
    • However there seems to be an inconsistency regarding its size, as its shown that Robotnik is holding single Time Stone in the ending cinematic, which is small enough to hold it in his hand.
    • The major difference between the Time Stones and Chaos Emeralds is that the Time Stones only seem to be able to warp through time on Little Planet itself.
