More than 100 people have retained a Los Angeles law firm over alleged brain injuries they say they suffered after riding the X2 roller coaster at Six Flags Magic Mountain near Los Angeles over the past two years.

Attorney Christopher Bulone, who represents the plaintiffs, said his most recent clients developed serious medical conditions after riding the coaster earlier this year. One rider, 25-year-old Naomi Greer-Wilkinson, remains on a ventilator following emergency surgeries, Bulone said.

Bulone said riders may not understand the potential medical risks associated with high-intensity roller coasters before getting on them. He argued that amusement park operators have a responsibility to prioritize rider safety.

The lawsuits are being handled by Dordick Law, whose managing partner Gary Dordick previously said the firm had been retained by more than 100 clients who suffered alleged brain injuries after riding X2.

The complaints name Six Flags as well as S&S Worldwide, the manufacturer of the X2 coaster cars, as defendants. Six Flags has declined to comment on the recent lawsuits.

The X2 has been closed since July as the lawsuits and concerns surrounding injuries associated with the ride continue to draw attention.

Six Flags also recently settled a wrongful-death lawsuit brought by the family of a 22-year-old man who died after riding the coaster in 2022.
