Warning: MAJOR SPOILERS for Invincible & The Walking Dead Comic Book Series! When one thinks of The Walking Deador Breaking Bad, their minds will likely jump to the two hit AMC television series. However, long before either show hit the airwaves, The Walking Dead was a comic book series created by Robert Kirkman - the mastermind behind Invincible as well. The reason that’s significant is that, even in the comic book landscape, The Walking Dead and Breaking Bad still share a connection, though not necessarily a flattering one. Indeed, Kirkman has actually shared his criticism of Breaking Bad, which directly correlates to how he chose to end The Walking Dead (and Invincible).
