A review by ppetropoulakis
Invincible, Vol. 11: Happy Days by Robert Kirkman

4.0

Mark is becoming more powerful as Invincible, although his brother Oliver, or Kid Omni Man, is quickly catching up in powers. The Viltrumites plan to execute Omni Man and Allen the Alien happens to be nearby. Alternate universe Invincibles, peeks into the future and a mediocre Wolfman plot thread make this an overall good read.
