The 1980s were a decade of multiple ownerships, original removals, licensed characters, high-thrill attractions and more. Six Flags Over Texas introduced mainstream figures into the park, including Pac-Man and the Looney Tunes. Major roller coaster additions included the Flashback!, Avalanche Bobsled and Judge Roy Scream.

La Salle's River Adventure was an interactive boat ride at Six Flags Over Texas from 1961, the park's opening season, through 1982. Equipped with riverboats, boat captain, and animated scenes, guests would learn about La Salle and his journey to find the Mississippi River in the 1600s.
