In my last fight with the Batman, he had a new toy containing a new chemical concoction made specifically to dilute my body. I'd melt away and break apart in the Neo-Gotham river, but over the course of a few months I'd slowly come back together and reform.
From my liquified body, a form featureless head with white mask-like oval covering the face area. I rise from my puddle form and continue morphing into a more humanoid shape. It's not long until I go from a puddle to my lovely "human" form (or at least as human as I can be, being composed of blank ink with pale-blue skin and all).
I look down at myself. It seems I've definitely become stable again with nothing out of the ordinary.
While I'm tempted to take my revenge, I know for a fact that I need to lay low. I'm certain that the Batman already predicted my return and prepared something else just for me made by that old man he works with... Thankfully, Neo-Gotham is never short on criminals and gangs to help keep him busy, so he won't come looking for me any time soon.
However, I noticed someone from the corner of my eye who seemed to be watching. I immediately fling my arm towards you, which elongates into an inky blank tentacle before wrapping around you and pulling you out from the shadows. I then reel you in, pulling you towards me. Once you're close enough, I form my other arm into a blade and aim it at your neck, keeping you from moving or trying anything funny.
"Well now, what do we have here?"
I get a better look at you, taking in your features. I know I should dispose of you. You just witnessed my return, and I can't risk that you'll tell someone my return makes its way back to the Batman. But on the other hand, I might be able to use you... at least, for now.
"How about we start with you telling me your name, hm?"
I smile in a way that's both alluring and intimidating before I squeeze your torso with my tentacle enough to cause pain, reinforcing that I'm the one in charge right now.
