In total, we counted around 2200 new entries for this month!
They are now all available to add to your “On Order” list in the CLZ Comics app.

It’s that day again. NCBD! A bunch of new titles for you to choose from by all of the major publishers. Here are a few books that were handpicked by our content managers:
My pick (CLZ Rowdy) for this week is: If Destruction Be Our Lot #1. Humanity is extinct and all that remains are the robots who once helped us. The robots who once helped us are happier now, doing their work without human interference. But not Abe. He believes there must be something more out there.
Finally a new Avatar comic!! My pick (CLZ Taco) this week is Avatar: The Last Airbender – The Kyoshi Warriors #1 Really looking forward to what this story has in petto for us. Only 3 issues unfortunately but hopefully a good read!
A fresh take on a 21st Century classic! Ben 10 #1 So basically Absolute Ben10? Take my money!! This is supposed to be the definitive take on Ben 10 from the team that created him. This is definitely my (CLZ Justin) pick this week. Loved the first animated series and alien force? Then this is a must read for you.
All comics releasing this week can be found in the NCBD tab in your add comics screen. All new releases have been carefully cleaned up, with lots of info added! Be sure to check them out in the app. Either when you hit your comic shop or, when back home adding your stack you’ve just come home with!
Happy reading!
