Kang can become an ever bigger MCU villain than Thanos in The Avengers 5 — but only if he kills two beloved characters. First making his presence felt in 2012's The Avengers, Thanos simmered in the background of Marvel's Phase 1 & 2 slates before finally emerging in 2018's Avengers: Infinity War. Phase 4 hasn't exactly rushed to replace the Mad Titan, but the leading contender right now is undoubtedly Kang the Conqueror, portrayed by Jonathan Majors.
Kang's tale began with Loki on Disney+. Tom Hiddleston's God of Mischief — alongside female variant, Sylvie — pulled back the Time Variance Authority's dark curtain, revealing He Who Remains (played by Majors) as the puppet master. Mr. Remains explained how one of his 31st century variants cracked the multiverse's secrets and met parallel selves from other worlds, but while some of these alternates were simply curious scientists looking to further their inter-dimensional knowledge, others — specifically Kang the Conqueror — used their power to dominate and oppress rival realities.

Though He Who Remains managed to fix the timelines and remove Kang from play, Loki and Sylvie (more Sylvie, if we're honest) removed the one safeguard holding back the flood. Kang will next feature in Ant-Man & The Wasp: Quantumania, and if The Avengers 5 does happen in Phase 5 or beyond, Majors' villain occupies pole position to torment Earth's mightiest heroes. Kang in The Avengers 5 would be the greatest possible payoff to his monumental introduction, but to become a serious threat, there are two MCU characters he must kill first...
