KRE-O is a line of construction toys (similar to Lego and Mega Bloks) manufactured by South Korea-based Oxford and marketed by Hasbro. Kre-O was released in stores in Fall 2011, although Hasbro started shipping out the first Transformers sets in early June 2011. The creators of the toy franchise got the name "Kre-O" from the Latin word "creo", which means "I create".
Kre-O toy feature highly articulated humanoid figures called Kreons.
Kre-O blocks are compatible with Lego bricks, hence also compatible with Mega Bloks and other building block brands.
Kre-O Star Trek was released as the fourth line of Kre-O sets in April 2013. The initial sets and Kreons are based on the 2009 reboot and its sequel Star Trek Into Darkness. A preview trailer was posted by Hasbro, first on Facebook, then later on YouTube. The trailer re-enacts the original "teaser trailer" for the first film, showing the construction of the U.S.S. Enterprise in Kre-O form and by Kreon construction workers. A press release made at the 2012 New York Toy Fair showed the completed Enterprise model (complete with flip-up "saucer" showing the ship's Bridge) and Kreons of Kirk, Spock and Sulu.
Kre-O Cityville Invasion is the fifth line of Kre-O sets, based on the popular CityVille online game series. This line introduces "Sonic Motion Technology", which triggers specific movements in special Kre-O bricks.
