Original ideas and concept is created by Mike Kime and Grim.exe is modeled by Mike Kime too this is his work https://www.artstation.com/artwork/GgJ6N. I just take Grim.exe over and dress him up a bit and create proper format for modelling. Grim is my fav carry for long time unfortunately he is nerfed just like most of concepted characters haha. Still have 8 more days to play my fav game, and I will keep playing until the last day of it!!
