Summary
There it was again blatant, undeniable. Mark’s dick, and Cecil couldn’t believe he was even thinking this, was huge. There wasn’t really a better word for it. The outline of his thick shaft was visible, pressing along his left thigh like it had nowhere else to go in that damn suit. It was obscene, honestly. Nobody should be walking around the GDA headquarters looking like that. Someone needed to get him a cup insert. Immediately. For everyone’s sake.

Summary
The earth is lacking in options, and few people know it as well as Cecil Stedman. As reality closes in, it becomes apparent to him that his job is fooling people into thinking they are safe more so than protecting them. That may change when a strange opportunity presents itself. In the form of a superhuman teenager with questionable tastes in men.

On hiatus due to life events (Fanfic writers curse has caught me). Will be back around the 31st of October. In the meantime, I have gotten a beta reader who is helping me adjust flow, details, and some minor story edits that may have been missed along the way. These will be posted as they are done, check before chapter notes to see if it's been updated if this is of interest.

Summary
Set in the Invincible universe, this follows a fellow Viltrumite (the reader) who is assigned to a mission alongside Conquest, one of the Empire’s most brutal enforcers. Both feared and respected, Conquest is a living weapon — and the reader, though somewhat equal in strength and rank, is brought in to “test his control.”
What begins as an unspoken challenge quickly turns into a brutal, passionate relationship. Their first physical encounter is raw, aggressive, and hungry- they match each other not only in combat, but in desire. the two develop a bond deeper than either expected- a connection forged through blood, war, and defiance. Eventually, their closeness draws suspicion from the Viltrumite High Command. Rumours swirl that Conquest is going soft. Orders are given to separate them, a calculated threat meant to break their connection.
Their parting is not goodbye. It's a promise: “I’ll find you.”

Except, that's not how this story will go. Gritty battles, close calls, losing those close to you. If Mark really wants to walk this path of a hero, then there is much he still has to learn.

Summary
She is a doll.
Eve comes to the realization when they wash her for the day. (Is this the first time they’ve done it? The fourth? The tenth? She decides it doesn't matter.) They’re quick and careful about it, scrubbing her down, brushing her hair, dressing her in pretty white scrubs. Like a doll. Like how she used to do with her Barbies before she made herself into a superhero. Before the world went to shit.
Or, my imagining of the alternate universe seen in Season 2 Episode 1 of Invincible.
