On Monday, Robert Kirkman teased the death of Mark Grayson in "Invincible" #100. Yesterday, the waters got murkier as Allen the Alien's death was similarly hinted at.

Today, it's Robot's future being placed into question as Image Comics has released a third teaser image for the centennial issue of "Invincible" featuring the hero's human form, wearing a Robot mask, bloodied and collapsed amongst rubble and wreckage. Kirkman and series artist Ryan Ottley determine the final fate of Robot, along with that of the rest of the "Invincible" cast, in January.
