Sonic the Hedgehog in the Fourth Dimension is a book written by James Wallis under the pseudonym "Martin Adams" and was published in the UK in 1993. Its story is based on the Kintobor origin story laid out in Stay Sonic (which in turn is based on Sega of America's Sonic Bible).
Sonic and Tails try to prevent Robotnik from altering history, encountering the Organisers–human scientists who maintain the laws of Time and Space–and helping them against the mythos creatures, paramilitary mythological creatures who are trying to exist in reality. Sonic briefly altered history so Kintobor never became Robotnik, but had to change it back to stop the mythos creatures altering the Big Bang.
