This is CLZ Alwin, with another “what’s cooking” version of our CLZ Newsletter.
Again, with the entire content and dev team working on three big upcoming releases, the month of March saw no feature releases whatsoever.
We did do some important maintenance builds though.

So… this is what’s cooking:

  • Various maintenance updates for CLZ iOS and Android apps
  • Coming up: Automatic book values for CLZ Books Mobile and Web
  • Coming up: Toys-to-Life support for CLZ Games Mobile and Web
  • Coming up: More “compact” look and layout for CLZ Web
  • Available tomorrow: CLZ Core for Comics in 12 leather bound books!

We’ve all been there, at an LCS, or at a comic con… you wanna check CLZ Core and bam… no internet, no data, no nothing.
Sadly, there is nothing our tech guys can do to resolve that problem, there’s no app for that 🙁
UNLESS… we go offline, oldskool and back to PAPER!

Available starting tomorrow: CLZ Core in 12 leather bound books

  • Purchase this beautiful set of 12 leather bound books for just US $495!

    The full CLZ Core database, all series, all issues, all variants, in actual paper books for your offline browsing.

  • Keep track of your comic collection. All issues are listed with checkboxes, so just use a pencil to checkbox the issues you own.
  • Wanna stay up-to-date with all new releases? We’ve got you covered! Subscribe to the monthly “Update from Core” paperbacks, for only US $5.95 per month, or US $60 per year. Receive all NCBD releases in compact booklets, sent to you on a monthly basis.


Variant hunters, get ready! We’ve got a SPECTACULAR amount of NEW SERIES premiering this week.

Hush is back! Batman, Vol. 3 #158 – or rather Batman #158 Hush 2 – not only reintroduces us to iconic characters, but also gives us the art of Jim Lee, Hush’s original artist. Prepare for a mysterious and action-filled story.

Vampirella is back in Vampirella, Vol. 8 and she’s bringing her infant son. Little does she know she’s indirectly responsible for a nuclear inferno waiting to happen somewhere in the near future. In order to prevent this she receives help from somebody unexpected.

And if you can’t get enough of Deadpool, then you definitely can’t go wrong with Pooluminati.
We all know the Illuminati supposedly is a highly secret organization, protecting Earth from evil forces and threatening menaces. Throw in a mix of ‘Pools, and the Merc with A Mouth and his daughter Ellie themselves, and you get a heart-warming story. Artwork by Todd Nauck!

So get ready for this massive list with big-name releases and plenty of cover options, making it the BIGGEST week of the year so far!

Happy Reading!

It’s NCBD, the best day of the week!

In Eddie Brock: Carnage #2 we follow Eddie Brock as he turns himself in to the police. Why would he do that? What are his plans? With Jesús Saíz and Charles Soule as artists you just knów it is going to be criminally good.

The Absolute Universe, the twisted reality created by Darkseid, sees many popular reimaginations of the World’s Finest heroes. Absolute Flash #1 begins with a teenage Wally West and the struggles he faces in daily life. His life will change forever when he meets military scientist Dr. Barry Allen.

If you liked the Saturday morning cartoons from your youth, chances are that you’ll lóve The Herculoids. In The Herculoids #2 the heroes deal with the aftermath of the alien treath of the last issue, while preparing for a new one. Location of this new threat? Right under their feet!
