Summary
Deep inside the intestines live 100 trillion bacteria of roughly three types; good, harmful and opportunistic. One of the bad guy faction does unintentional good in contribution to the digestion of food in the underwater alien world of the intestinal tract. As he sinks his own tentacles, shimmying into the rhythm, he enjoys himself contently in his life inside the intestine he lives in, exchanging food and shelter for hard work he gives off in the deep trench of the intestine with unexpected joy.

Summary
In the bustling immune system of the human body, Helper T Cell is all discipline and duty—until he’s paired with the glitter-loving chaos that is Dendritic Cell. From jazz hands antigen presentations to overnight stakeouts in the lymph nodes, their partnership is anything but smooth. As infections rise and flirtation sneaks into battle plans, the two immune warriors find themselves caught between professional tension, personal denial, and one very inconvenient mutual attraction.
Love, like inflammation, is hard to regulate.

Summary
U-1146 is a model White Blood Cell: silent, serious, and deadly efficient. Dendritic Cell is… none of those things. He documents immune activity with glitter, hosts educational puppet shows, and keeps a growing scrapbook of U-1146’s most humiliating moments.
But when a dangerous infection threatens them both, teasing turns to tenderness—and behind the mockery, something real begins to grow.
A slash fanfiction full of immune puns, emotional ambushes, and one very confused neutrophil trying not to fall in love.

All 3803 wants to do is prove she’s mentor material… but there’s something about little miss perfect she doesn’t know, and she's not the only cell having an off day—as she’ll soon realize when she runs into U1146, or rather, when they're both running for their lives.

Summary
Just a little semi-fluffy PWP one shot between two drunk blood cells. lol Wrote it because I was like "what if 1146 took AE3803 out on a date and got drunk?" Not sure why I made it like a first date situation.
This isn't even headcanon to me; it's just a fun little thing I wrote up and decided to share with the world because I felt we all need to read about how two intoxicated cells sex it up with each other. lol
Hope you all enjoy!

Summary
When U1146 meets AE3803 after killing a bacterium, she offers to share a meal with him to the distress of everybody else. After learning what neutrophils eat, AE isn't grossed out at all and after a particularly awkward confession of feelings that neither her nor the White blood cell understood, she decides to do something very weird... But in the end it becomes the best idea ever!
