In 1979, the park was sold to Six Flags and became known as Six Flags Magic Mountain.
In 1981, Six Flags Magic Mountain introduced a ride that was on the west coast for the first time called Roaring Rapids.
It was developed by Intamin in conjunction with the now defunct Six Flags Astroworld, which had opened a similar ride in 1979.
Along with Rapids came the completion of the midway near Spillikin Corners to link with Revolution's area.
Finally, a complete circuit could be made around the park.
It was originally designed as a dual-sided station, but only one was fully developed, and all that exists of the possible second side is a few supports.
It uses large pumps to circulate water, and each of the two pumps can circulate 88,500 gallons per minute.
The reservoir can hold 1.5 million gallons of water, and one of the innovations used on it was the introduction of guide boards to help eliminate jam ups.

In 1982, the attraction Freefall was added.
Also built by Intamin, it was considered a cutting edge drop tower ride, if not strictly a "roller coaster."
It simply ascends the tower and then drops down, with the track curving to horizontal, leaving riders on their backs.
Others were built for other parks (some of which are Six Flags).
Today, most of these rides are obsolete and have been removed.
Some flat rides were added and others removed the next year.

In 1984, Sarajevo Bobsleds was erected.
Yet another ride built by Intamin, the coaster was basically a bobsled without ice and snow.
The coaster was built in honor of the 1984 Olympics.
Six Flags Great Adventure added a similar ride that same year.
In 1986, Sarajevo Bobsleds was removed and now operates at Six Flags Over Texas as La Vibora.
The other bobsled was moved to Six Flags Great America and later to The Great Escape in Queensbury, New York, where it operates as Alpine Bobsled.

In 1985, Children's World was rethemed as Bugs Bunny World, as Magic Mountain had abandoned the Trolls in favor of Warner Bros.' Looney Tunes/Merrie Melodies characters.
That year, Michael Jackson visited the park, riding rides such as Colossus, Revolution and Roaring Rapids.
In 1986, the park added a steel stand-up looping roller coaster called Shockwave also designed by Intamin.
This coaster was located in the back of the park replacing Sarajevo Bobsleds.
At the end of 1988, the coaster was removed as part of a ride rotation program and went to Six Flags Great Adventure in 1990.
It was removed from there in 1992 and was repainted white and rethemed upon its removal to Six Flags Astroworld.
There it was known as Batman The Escape.
When Astroworld closed in 2005, the ride was put in storage at Darien Lake.

In 1987, the park re-themed the Back Street.
Spinning flat rides were renamed Turbo (Electric Rainbow), Subway (Himalaya), and Reactor (Enterprise).
The dance club was rethemed as well, and located near Reactor.
After Hours, as it was now called (formerly Decibels), for one summer stayed open later than the rest of the park.
It, along with Back Street, would stay open an additional two hours as a place for locals to hang out.
This format lasted one season.

In 1988 Ninja, "The Black Belt of Roller Coasters", opened.
Built by Arrow Dynamics, it was the first suspended swing roller coaster on the West coast.
Ninja has gone through very few changes since it was opened in 1988; evidently only the wheels and paint have been changed.

Tidal Wave opened in 1989.
It is a short, wet ride featuring a large boat that travels up a low-angled incline to a level water trough.
The trough, in the shape of a semicircle, ends in a steep drop into a large splashpool.
The impact displaces large amounts of water on its riders.
The ride's exit ramp crosses over the splashpool, allowing willing patrons leaving the ride to get soaked from the splash.

In 1990, Viper, a multiple looping coaster designed by Arrow Dynamics opened.
It features a 188-foot (57 m) drop, speeds up to 70 mph (110 km/h), 3 vertical loops, a batwing turn that inverts riders twice, and a double corkscrew.

In 1991, Magic Mountain added Psyclone,
