All SPOILERS relating to Uncle Adam and the canon series are unmarked!!!
Breaker of Horns (Hellaverse) has the following examples:
- Adaptational Villainy: Lucifer and Lilith - two times actually. First compared to their canon selves: Canon!Lucifer is mostly depressed and apathetic to his subjects' plight and Canon!Lilith is Ambiguously Evil but in present days apparently just wants to be left alone on Heaven's Beach. There's no indication either of them would be willing to sacrifice billions of souls - both living and dead - to rekindle a total war against Heaven. Second, they are shown to be more villainous than their counterparts of Uncle Adam - even though said counterparts are already a case of Adaptational Villainy. In Uncle Adam, Lucifer and Lilith are engaged in a cold war against Heaven, and are willing to sacrifice their own subjects if it means gaining an edge. However, their schemes don't reach the horrific scope of the one they enact in Breaker of Horns. It's even hinted they don't expect to be able to win against Heaven - when hard-pressed on the topic, Lucifer confesses he believes victory to be an impossible dream, and it's pretty explicit he doesn't have a clear plan in case he actually managed to pull off a win.
- Anti-Anti-Christ: Lilith and Lucifer tried to prop up their daughter to be the Antichrist to finally topple Heaven and make them answer to their views, only for Charlie to do the opposite and slay them in turn.
- Bittersweet Ending: Charlie had to kill her parents, whom despite everything she still loved dearly, for the sake of preserving Creation. Predictably, the act shatters her. However, the story ends up on a hopeful note: Charlie is slowly recovering from her emotional scars, she becomes Queen of Hell and finally manages to build a place to rehabilitate sinners - with already a thousand souls redeemed after a few years -, and Adam and Lute had children.
- Combat Pragmatist: When Charlie kills her parents, she doesn't give them a chance, backstabbing Lilith and ambushing Lucifer in his workshop.
- Due to the Dead: Heaven gives Lucifer and Lilith a proper funeral out of respect for Charlie and for who they used to be before they fell.
- Even Evil Can Be Loved: Lucifer and Lilith are a lot more evil in this story, but Charlie still loves them deeply. Lucifer's angelic siblings also mourn him during his funerals.
- Face Death with Dignity: After recovering from the shock of having been betrayed and skewered by her own daughter, Lilith spends her last moment quietly gazing at Charlie, so that her child's face will be the last thing she sees before she dies.
- Kill the Ones You Love: Due to her parents' horrific planning on creating an event similar to the Book of Revelation and propping her up as the Antichrist, Charlie made the difficult decision of committing Matricide and Patricide (along with any of their collaborators) to prevent that from happening.
- Meaningful Rename: Charlie broke her name Morningstar through the act of killing her parents. Once she's ready to take the throne of Hell, Adam bestows the name Guidingstar on her.
- Never the Selves Shall Meet: When trying to teleport to Earth for vacation, Charlie ends up meeting the "canon" cast of Hazbin Hotel after the death of Adam. The results were...obviously less ideal.
- Point of Divergence: At some point in Uncle Adam, Lilith and Lucifer continue their cold war against Heaven and decide to invoke an event similar to the Book of Revelation.
- Recursive Fanfiction: Of AkumaKami64's Uncle Adam.
- Try to Fit That on a Business Card: After she becomes ruler of Hell, Charlie's full titulature is: "Queen Charlotte Guidingstar: Ruler and Magistrate of Hell. Aegis of Heaven and Earth. Justicar for Redemption. The Breaker of Horns."
- We Used to Be Friends: Adam remembers a time he and Lucifer were friends, but those times are long gone, and only subsist in a few bitter memories.Adam shakes his head from the memory. The angel who’d been his friend, if he ever was his friend, was long gone. Replaced by someone who would risk the destruction of all Creation just to satisfy his damn pride.
- What a Senseless Waste of Human Life: After spending so much time hating Lilith and Lucifer and wishing for their deaths, Adam is a bit surprised not to feel any satisfaction when he finally sees their corpses at his feet. He mostly laments the wasted potential and feels angry at them for going so far off the deep end that Charlie had to kill them.
