I believe that this Pokemon can star in a lot of horror movies because of that hilariously stern face it makes. It just needs to stand there staring at someone in dark corridors or rooms in an abandoned building and maybe slowly walk over to the scared human(s).
Dolliv is a grass type and is the evolved form of Smoliv which makes it's third evolution Arboliva. They're known for acting the most human aside from Gardevoir, helping their human masters in daily task and such. After I first saw the stern face of this Pokemon I had to draw it.
