A pokemon concept that is a mix of many old pokemon I made in the past and new alolan creatures. ^^ I am still working on his story. Comments and feedback are appreciated! :D

Amalgoo
The Gooey Jackal Pokemon
Type: Dark/Poison
Size: Varies
Evolution: None
Abilities:
Mass Index: Changes form depending on HP

Amalgoo is an extra terrestrial pokemon with anatomy similar to Deoxys. It's body is made up of a red jewel-like core and a purple ooze. If near fatally injured and all ooze is stripped off the core it resembles a small pokemon egg. as long as the core is intact Amalgoo can regenerate to his first form. At first the shifting of forms was thought to be evolution but Amalgoo doesn't not glow when changing and a large lose in mass will change it back to a smaller form.

First observed form: A canine creature; it's shape seems similar to a mixture of a Vulpix, Riolu or Lucario. The mantle and tail of this form seems to shift between a silky dark purple fur and ooze. The mantle parts over the chest where the jewel core is visible. Amalgoo is capable of creating tentacles from it's mane. The pokemon is also observed to never open what are thought to be eyes and so the head may just be for looks. Amalgoo seems very concerned with keeping clear of dirt, debris and mud.

Second observed form: Amalgoo has grown larger from hunting down Grimers and Muks. Instead of making tendrils or tentacles from it has permanently created furry arms from its mantle after observing a Machamp.

Third observed form: After absorbing and gaining vast amounts of goo and exposure to dragon pokemon and Buzzwole Amalgoo has achieved a new form. In this new form is bipedal and sports 4 muscled arms. Resembling Buzzwole many of its muscles are now a luminescent purple. The creature is much less canine and more dragonic but still sporting a canine head. This form seems still unhappy and seaking more to add to its mass. After larger meals it's seperated abdominal panels merge into a large glowing gut. Is this its final form? probably not.
