This is NOT ideas/proposals thread. This thread is for discussing what the community managed to confirm or at least has a high probability of being in LoG2. If you want to propose new monsters, there's New monster proposals thread.

I will keep updating this list as new details emerge.

Forest ogre confirmed - See AH blog here
Insectoid under consideration by AH - See Petri's post.
A monster with lots of holes confirmed, details missing - Jykä mentioned this monster in his blog intro (see "What are you currently working on?").

Here's what we know about this new monster that Jykä mentioned: A monster with lots of holes and obscurity surrounds this little “fellow”. I would speculate that it's an ent or other tree like monster. This would be a sort of continuation of herders theme.

I should think it's a cheese slime with a lot of personality.

Lets not forget the April 25th blog post:
"Jyri has also helped Juho and Olli by creating the very first monster that you will encounter in LoG2! Jyri reports that the monster has 3192 polygons, uses three textures, has 17 deformers and fits approximately inside a 3×3 meter cubic block. Can you guess what it is?"
