Sacha Baron Cohen Unveils Dramatic Body Transformation for Marvel’s Mephisto Role

Fans got their first look at Sacha Baron Cohen’s astonishing physical transformation this week when Men’s Fitness UK released a cover shoot of the actor shredded and shirtless ahead of his debut as Mephisto in Marvel’s upcoming Ironheart series and related films. Trading in his trademark comedic characters for a sinewy six‑pack, the 53‑year‑old worked with celebrity trainer Alfonso Moretti on a strict regimen of daily 25‑minute circuits focused on push‑ups, kettlebell swings, and core work, complemented by a high‑protein Mediterranean diet.

Marvel insiders say Cohen’s revamped look aligns with the studio’s darker take on Mephisto, described as a “charismatic demon in a three‑piece suit” who will weave through multiple Phase 6 projects. Costume fittings reportedly required digital scans of Cohen’s new dimensions, while early camera tests sparked comparisons to Josh Brolin’s Thanos metamorphosis. Production sources add that the actor has undergone vocal coaching to develop a gravel‑toned menace far removed from his previous roles as Borat and Ali G.

Reaction online has been swift and largely positive: fitness influencers praised the achievable workout plan, while MCU fans flooded X with memes celebrating “Shred‑a‑Baron Cohen.” Critics, however, warn that the drastic change could overshadow the performance if marketing leans too heavily on shock value. Either way, Marvel appears poised to leverage the buzz, teasing that an official Mephisto teaser will drop at next week’s San Diego Comic‑Con panel.
