Third Teaser Leak Sparks Frenzy

Late Sunday night, multiple social media accounts began circulating clips of what is claimed to be the third teaser. Shot discreetly inside a theatre, the footage quickly grabbed attention despite its rough quality.

At the centre of the visuals is a haunting image: the Xavier School for Gifted Youngsters engulfed in flames. Patrick Stewart’s unmistakable voice echoes through the clip, reflecting on survival amid chaos.

The teaser also offers a powerful moment of reunion, showing Stewart’s Professor Charles Xavier in conversation with Ian McKellen’s Magneto- an interaction fans have been eager to see within the MCU framework.

The teaser doesn’t stop at nostalgia. A brief but striking shot reveals Sentinels tearing through their surroundings, followed by Cyclops unleashing what appears to be the most intense optic blast ever shown on film.

Though the original clip was grainy, clearer AI-enhanced versions flooded timelines by Monday morning, amplifying excitement.

Online Buzz and Fan Reactions 

The internet response has been overwhelmingly enthusiastic. Many viewers have hailed the teaser as superior to the earlier previews, while the Cyclops moment has gone viral. Fans have gone so far as to call it ‘better than anything Fox ever did’, a pointed reference to the earlier X-Men films produced by 20th Century Fox after acquiring the rights in the 1990s.
