'''Basic Trope''': A character saved another character's life by turning him/her into something more or less human.
* '''Straight''': Bob saved Alice by turning her into a demon.
* '''Exaggerated''': Bob turned Alice into an EldritchAbomination to treat her badly stubbed toe.
* '''Downplayed''': Alice stays human, but she looks [[TheOtherDarrin like a different person now.]]
** Transformation is akin to the healing arts, but before he set out on his quest Bob was only taught one thing that could save Alice before her injury killed her.
** The transformation completely replaces the victim's body, including any injured parts.
** Bob gets transformed into a demon by Alice to save her life.
** Bob has VoluntaryShapeshifting powers, but finds out that he will die unless he gives up his powers.
** Alice transformed due to natural causes (rather than the transformation being invoked), and the process is so [[PainfulTransformation painful]] that it almost ''kills her'', rather than saving her life.
** Bob changes Alice into a demon after she is lethally wounded, but she dies of the wound anyway.
** Alternately, she dies [[DownerEnding before the transformation is finished]].[[note]]Also averts TransformationIsAFreeAction.[[/note]]
* '''Double Subverted''': After that she comes back as a full demon.
* '''Parodied''': Alice gets a vase dropped on her head, Bob turns her into a dog to prevent possible brain damage.
* '''Zig Zagged''': Bob turns Alice into a demon to save her life, except Alice manages to pull through on her own, however it's because Bob only gave her the resilience of a demon rather than fully transform her.
** No one has any injury that warrants such a treatment.
** Bob's transformation spells don't heal as a side effect, and any new immunities or healing factor take long enough to kick in that the target will still die of their injuries or illness.
* '''Enforced''': Bob, Charlie and Dylan have already been turned into a werewolf, vampire, and ghost respectively, and for Alice to stay on their same PowerLevels and keep up she needs to be changed into a demon or the like.
* '''Lampshaded''': "Great, I get a sword through my heart and now I can't go anywhere without [[EvilDetectingDog cats hissing at me."]]
* '''Invoked''': "We need some way to mix things up between Alice and Bob, but romantic would be just too easy."
* '''Exploited''': Alice knows Bob has a spell that can save someone's life by turning them into a demon. So Alice proactively gets a ProtectiveCharm placed on her that will keep her soul from being tempted with evil powers and/or sent to hell as a result of demonic conversion. Then she goes on a SuicideMission knowing she can come out alive ''and'' more powerful.
* '''Defied''': Alice refuses to be turned into a demon, even if it would save her life.
* '''Discussed''': "So, Bob, about that 'Turn people into demons to save their life' spell... consider this my formal 'Do Not Resucitate' notice. [-Do Not Redemonate?-]"
* '''Conversed''': "Meh. This show doesn't really have any hot chicks." "Oh, just wait. Bob has a spell that can turn people into demons. My money is Alice gets an EvilMakeover after a near death experience." "Color me intrigued."
* '''Deconstructed''': Alice, after seeing she is a demon, becomes horror struck and soon after she loses all the qualities Bob saved her for in depression and self-pity.
* '''Reconstructed''': Right before Alice goes to the point of no return emotionally, Bob realizes what's going on and has a long talk with her, giving Alice only a stronger resolve to help Bob in his quest.
* '''Played For Laughs''': Alice practically forgets that she's a demon, and continues with every day life while ignoring the terrified looks she gets from everyone.
* '''Played For Drama''': The transformation keeps Alice alive, but alters her personality just enough to make her believe that everyone fears or hates her now, driving her to lose what little humanity she has left, and she becomes a demon mentally as well as physically.
Their heart is almost hit! Wait for me at EmergencyTransformation and we can use the hell crystal to try and save them!
