ThunderCats, one of the biggest TV animation premieres of the summer, has a new sneak peak. Nine minutes of the pilot episode is available for previewing. Based off the popular 1980s cartoon, the reboot takes the ThunderCats universe in a whole new direction. The animation is cleaner and slanted towards Japanese anime. It was animated by Studio 4°C. The plot has also changed with Lion-O being more of an adult at the beginning and Snarf regulated to a less annoying sidekick. The series will premiere on the Cartoon Network on July 29.
