This is the kind of stuff she can use just in Central Park, though the swarm she keeps under her costume has a lot of stuff. Venomous, poisonous, some dipped in caspacin (pepper spray), etc. She's probably not going to immedately send out her personal swarm since that's used more as a concealed weapon, but she can get straight to summoning all the bugs in the area to mob Giovanni really hard. Once controlled millions of spiders at once to keep
Crawler (Worm) incapped, and much later on says the issue with getting quintillions would be that it takes way too long as opposed to the number itself (though that was after her power was messed with, so eh). Bugs also survey the area and can act as a sort of low level clairvoyant power, giving her generally enhanced awareness of what's going on. Her voice can be projected, swarm clones of her can be made to confuse a foe, and bugs will often be sent to vulnerable areas. Her first thing she did was rot a man's dick off (but it's okay he has Regenerationn).
Taylor herself is also good in combat. The gun and matter destroying knife are out, but she still has a baton and pepper spray, alongside her concealed swarm. She was able to stall
Mannequin (Worm) long enough to gunk up his mechanics with spider silk despite her significant physical inferiority, escaped
Coil's plot to have her assassinated which involved fighting through Coil's mercenaries while still mostly blind and relying on her swarm sense to get stuff done.
The biggest thing Giovanni seems to have going for him is the steam aura, but there are a few ways she can get around that.
- Having bugs drop things from trees, like nests and branches and such. Falling objects will hurt a 10-A dura
- Just swarming anyways, since steam won't instakill bugs and bug corpses fill eye sockets, noses, lungs, etc just as well as living ones
- Using bugs that can tolerate that better
- Just beating him up herself, since she's physically stronger, faster than his normal speed, has a baton, is pretty good at fighting, and has her hidden swarm.
She did beat a dessication focused cape brought in pretty much just to make her powers not work well, though i don't; remember how. All in all I think I'll vote Taylor here.
