Darky-human form

beside Dark Dani, from Dark Danny's ''plan B'' also created ''a by-product'': Darky, a mute, creepy 4-years old girl that hold shards from Dark Danny's memory, that appears as nightmares.becuase of that, she's of everyone (they remaind her nightmares) beside of Dani (that wasn't existent in Dark Danny's timeline), so Dani is taking care at her ''littel sister''.
