Kang Already Proved He's Deadlier Than Thanos with One Stunning Fact
Both Thanos and Kang the Conqueror are in the upper tier of the most powerful villains in the Marvel Universe, but a single scene showing the Avengers the latter had killed proved who is deadlier. In Uncanny Avengers #U8 by Marvel Comics, Kang visits his armory in the far future, showing off the trophies he earned after killing Earth's Mightiest heroes across time. Admitting he beat each hero in battle in hand-to-hand combat, Kang proved he's more violent than Thanos.
