In the final battle of one of the next seasons (like maybe season four) Lute gets defeated by Vaggie and the main cast and loses her robotic arm in the process. Because she committed treason by leading The Exorcists army down to Hell for no apparent cause and without the knowledge of Sera and The Elders, she gets banished from Heaven and sent down to Hell. Once she hits the ground of Hell, she ends up falling unconscious for a little while. As she starts to slowly wake up she notices that a strange serpent/centipede like creature approaching her, she tries to get off the ground but she’s too weak from the fall and her missing arm is making it difficult for her to get up. The creature slithers up her back and makes its way to her arm stump and before she knew it the creature had attached the end of its body to her arm stump. Then suddenly, her eyes begin to glow green and scenes of her from the previous seasons began to flash before her and our eyes until she falls to the ground unconscious again. After Lute wakes up she slowly but weakly gets up off the ground, but as she does she notices that something is off. She's not struggling to get off the ground at all and the left side of her body (particularly the arm stump) fells like it doesn't have a missing body part anymore. Confused, she slowly turns to look at her arm stump, only for her to find that the serpentine/centipede like creature is still on her arm stump. Before she can pull the creature off her stump, she notices that the creature had grown into the arm stump and has now become a part of Lutes body and has given up its own independency for Lute to move and control it as if it were her arm. She then starts to make the creature move independently by moving it left, right, up, and down. The creature then looks at her with curious look and head tilt until it gives her a like on the face which makes her jump in surprise. Lute’s confused and surprised face begins to turn into a sadistic smile as she then begins to get up off the ground and starts to pet the creature, giving it scratches underneath its chin and then quietly says “thank you”. After saying this, the creature’s mouth begins to glow bright orange and Lute while confused at first glance, quickly realizes what it’s going to do and with an evil smile she points it to the sky as it breathes fire akin to that of a dragon or a flame thrower. Lute begins to laugh maniacally and the creature gives a sadistic smile similar to her’s and the camera zooms in on the two one last time as Lute then says “We’re coming for you Vaggie.” before the scene cuts to black.

The lore behind this creature is that it’s basically a living limb prosthetic that travels around Hell to find a host with a missing limb and bonds with said host by attaching it self to the hoast and becomes their new arm, hand, leg, or even finger. This creature has many abilities as when they bond with their host they start to feed on their minds and emotions and after they’re done bonding with their host they begin to act like them, think like them, and behave like them and depending on what the host is like as a person, the creature can either become good, neutral, or even evil. And since this individual’s host is Lute the creature is now evil and sadistic like her. It can also extend its body so that their host can use it like a rope or swing across a large gape, The creature is also semi immortal because If their head gets chopped off the head will grow back and if they get cut or ripped of the stump of the missing limb they attached them selves to they grow back on said stump. This is because as when they first attach themselves to their hosts they planted multiple spores inside their hosts body and those spores are clones of the creature so that when the original or the other clone gets cut off they will be reborn and still on the stump. However, they aren’t fully immortal as they can still die if they and their host get burned alive, blown up, or even melted alive by lava or something. As for the name of this creature, I’m not sure as I don’t really think ahead a time to think about these type of things. Although I was thinking of calling it something along the lines of either Prosthetipede or Cobretic. I think I prefer Prosthetipede more but what do you guys prefer. And in case you’re wondering, yes, this thing is basically the Tormentipede from the unreleased HTTYD fire tides comic.

I have a fun arm upgrade idea for Lute if she ever became a fallen angel in a future season.
