Malachi - The large one.
Ren - The human.
Dayshaun - The small one.

Malachi and Dayshaun are Dark Shift, or Shiftians. A fictional race created by me.
Malachi and Ren are lovers, Dayshaun is their child. Normally Malachi prefers his humanoid form, but since Dayshaun is too young to take his own humanoid form, Malachi prefers to interact with his son Dark Shift to Dark Shift.
Here is Malachi's humanoid form:

Here Malachi and Ren comfort their quasi-clumsy son who has hurt his foot.

You can make your own Dark Shift!
