Battle Beast battles Thragg
There are a few different plots in this volume: Battle Beast fights against Thragg, Oliver has a brother (or two), the aftermath of Rex's take-over of the planet (more or less), the baby gets a name and Mark moves off-world.
Interesting story-lines blend with clear artwork to make this a good addition to the Invincible story. Enjoyable and worth a look.
