In the Marvel Cinematic Universe, there'll always be that discussion over who's the most powerful character. Some would say Thanos, although he may need the Infinity Gauntlet to back his claims up. Others would argue Thor, but he'd require Mjolnir or Stormbreaker, while Doctor Strange would need his trinkets and relics, too. Many think it's Carol Danvers, due to the Infinity Stone (Tesseract) power her Captain Marvel has within.
