Likes 
+PromptsEstablished relationship body worship with very little dialog and lots of body language, very niche AUs (librarian, art restorationist, beekeeper?) that you just happen to know a lot about, mythical monsters, avian sheith wingfic or art, xeno slice of life, tattoo'd sheith, quiet atmospheric moments together
+TropesHuman/other including xenobio, android or supernatural beings, friends to lovers, enemies (actually) who save each other's lives and wonder when it all changed, hurt/comfort, only one bed, getting together
+Kinksxenobiology surprises, wingfic, tail fucking, body insecurity met with body worship, gentle dom, loving sadism, biting, praise, degradation, breathplay, choking, edging, overstimulation, cumplay, mouthplay, ritualized pain play like scarification/branding, electricity, fire, sci fi-creative sensation play, somnophilia, dubcon is cool with sheith imo so long as there's context that makes sense
+ShipsMHA rampant multishipper, bkdk OTP, v into tdbkdk; JJK satosugu; Trigun vashwood, plantcest, and plantwood ot3; VLD sheith OTP, also keitor, heith, kidge, leithal (Lotor/Keith/Allura), shirocest, uliro, mattor
+IdentityI headcanon Shiro as gay and Keith as bi/pan, can see either as gray/ace as well, and trans male or enby sheith is ♡; stealth trans Bakugou, enby Jirou, t4t MHA ships in general
Nopes 
/TropesCheating, love triangle, toxic monogamy, revenge fantasies, mean top destroys a former bully, manipulation, bad blood ex's, fake dating, miscommunication can be ok but make it make sense, mafia or law enforcement AUs, soulmate-verse tropes like red string
/Canonvld s8 including character death & epilogue in general
/KinksBratty behavior, infantilizing subs or bottoms, daddy kink (meh), breeding, pregnancy; I don't go for noncon between sheith (okay in shiro/other or keith/other)
/NOTPsitafushi; klance, shurtis, Curtis in general; izucha, anything Blood Riot or villain kiribaku (do enjoy bkkr/krbk otherwise)
/IdentityGenderbend with she/her pronouns for sheith or other faves (not a total no but I'm extremely fussy with it so...), removing canon disability, disability-centered angst, ableism, bigotry 🤷

Use Statement

You do not need to ask my permission to podfic, translate, or create any kind of fanart or remix (transformative fiction inspired by my stories), providing you don't make any money from it.I expect that you will:
- Always link to my original work
- Always credit me (bioplast_hero) wherever this is shared
If a fic of mine is itself a remix of another fic or in collaboration with another creator (always explicitly stated in my work), check with that author/creator.Fanart posted publicly should tag my social media and link to the fic that inspired your creation.Translation/podfic/remix should be posted to AO3 with my work listed as the related work. Check the box for "This work is a remix, a translation, a podfic, or was inspired by another work" and link my fic directly that way.Example of posted podfic//I do NOT give permission for commercial use, reposting my work on other platforms, copying or publishing my work without my knowledge or consent.I'm invoking creative commons license rights.If anyone finds my work for $ sale i.e. on amazon, or posted on any fan fiction site that is not AO3, you can assume it's stolen. And yes, this has happened. Please @ me on any social, comment on any of my fics, and basically point me to what you found; I'll be grateful.
