Concept art
One of my designs so, no concept art. I was asked to create several monsters for the stretch goals and I was given a whole lot of freedom in making them and one of the things I really wanted to make was a mutant-hammerhead-shark-zombie.
I thought an abomination that could ignore things like barricades and doors would be a cool so he was sculpted with that in mind; I added bits of wood planks sticking out of him to hopefully make it look like he just smashed through something. I'm not sure if that's what he does now but that was the original thought I had for him.
Here's another fig I did for the Dead Men Tales project, another early one from about 8 years ago. Tidebreaker sounds better that "Lumpy" which was his project nickname.
