Part of the transformation has seen the entire 250-tonne, 716-metre-long track replaced as well as a complete update of the beast which gives the ride its name.

Now a striking animation and image released today by the resort shows a single, giant blazing red eye, ringed by razor-sharp teeth sitting at the centre of the creature’s head.

Tentacles snake from its body, studded with the same, vicious teeth. Huge, powerful claws extend from its muscular midsection as it propels itself on nimble, black legs. Behind it trails a tail that it whips with bone-crunching force.

Fans were recently given a heart-stopping hint of the sheer power of the beast in an action-packed video that indicated that it had escaped from its secure containment at Alton Towers Resort.

On its opening in 1994 Nemesis was crowned Europe’s first inverted roller coaster and has gone on to develop a cult status amongst thrillseekers globally.

Millions of fans from around the world have visited the Staffordshire theme park to experience the thrilling 3.5 G-force, as the ride dangled thrillseekers along numerous twists and turns at speeds of up to 50mph.

Bianca Sammut, Divisional Director at Alton Towers Resort, said:

“Nemesis is utterly cherished by generations of thrillseekers. As Europe’s first inverted rollercoaster it occupies a special place in the heart for so many. At Alton Towers Resort we’ve been working tirelessly to transform this iconic attraction and we’re delighted to give fans a first look at the terrifying creature that gives it its name. This year fans will be able to experience the stand-out thrills of Nemesis Reborn for themselves. We’re keeping tight-lipped about the exact date of its return for now, but we can assure you … the wait will be worth it.”
