These frightening mash-ups come from Beth Emery/Zsparky, who has a gallery you can check out at DeviantArt. That Cubone and Colossal Titan mix is rad, but that Smiling Bulbasaur and its teeth are terrifying.
The work of Davide De Agostini is the story of past and lost humanity. It is the story of the dissolution of the forgotten memory and screaming, sore and dumb, to be recalled to memory, and fade for fear of being recognized for what it has become. It is the presence of witnesses silent, patient, invisible but sometimes guessed, passive in their solitude, active in the simple existence, and waiting for eternity.
