Last stage of some older fakes of mine, looks like crap I know. xP But whatever I'm posting it anyway since I've been avoiding to post it since I drew them.
Though despite the crappy designs, this Pokemon is rather unique. Its the first evolution of 2 Pokemon that count as a single species. You only need 1 of the 2 managoul to fill your Pokedex. However you need to own both previous stage (jelligoul and skelegoul) to cause the evolution.
Both need to be holding an item (together Stone) and both will then proceed to evolve.
You cannot stop either evolution, both will evolve after the first battle you have after attaching a together stone to each Pokemon.
