I find enjoyment in the idea of Pico, the guy who can take a bullet and get stabbed or slashed and has been literally flamed, having a phobia of needles. I've only seen this headcanon about at least 2 times (I may have seen it more than that but idk) and apparently that's enough to make me love the idea and envision scenarios where Pico is anxious to have a needle insert him.

I mean, he's all for getting vaccinations and piercings and such, he just hates the idea of a needle being put into him for a prolonged amount of time, especially when there's nothing to numb the pain with.
