The Monster is an inverted roller coaster at Walygator Parc, Maizières-lès-Metz, Lorraine. It is one of the biggest and the first Bolliger & Mabillard roller coaster in France.

It opened May 13, 2010 after numerous postponements.

The Monster


This roller coaster used to be operational in Expoland (Japan) from 1996 to 2007, named Orochi. It was relocated to Walygator Parc in 2010.

The Monster is nearly an exact clone of Raptor at Cedar Point; The Monster does not have brakes on the mid-course brake section after the Cobra Roll, and instead just has a flat section of track (although video of Orochi shows that the coaster had these brakes in Japan.)

The layout[edit]

The ride begins with a left-hand turn into the lift that ascends 131 feet (40 m). At the top, the inverted train dips slightly before turning left ninety degrees as it drops 119 feet (36 m) down the first hill. From the bottom the train immediately enters a vertical loop. Next is the zero-g roll followed by the cobra roll which inverts riders twice.

After the cobra roll, the train climbs through an upward spiral and enters a straight section. Next the train dives down to the right transitioning into a brief straight section of track. Riders then enter the first of two corkscrews which rotates the train 360 degrees to the left. The track straightens briefly again before turning to the right and entering a short dip before taking riders into the second corkscrew (this portion of the ride is often referred to by enthusiasts as the "dip and flip"). The ride finishes with a 1.5 revolution flat helix where riders encounter strong positive G-forces before making one last left turn into the final brake run.

Late opening[edit]

The construction started in January/February 2010. Because of harsh weather, work began later than scheduled, and the inauguration, initially planned for April 10, 2010, was deferred. A second inauguration deferment occurred mid-June because the TÜV didn't approve opening the roller coaster, then, the park hasn't communicated any inauguration day until the coaster could open July 9, 2010 (without its painting).[clarification needed]


The Monster is antiseismic, consequence of its previous location in Japan.

Height & speed[edit]

The park announced a speed of 68 mph. However, this information is incorrect. Actually, it was written on the manufacturer's informations a speed of 55.9 mph,[1] the speed is the same as when it was in Japan.[2] The velocity hasn't increased during the move. This difference between the 'commercial' speed & the real speed is probably due to the same exaggeration like they did for their other roller coaster called Anaconda. The media just kept repeating the commercial slogans provided by the park without verifying the truth.[citation needed]
