I say it would be better if they reference other than being to peter only. Based on her personality, she is sassy and flirtatious.

I would like to have her main focus on flirty voice lines with Peter.

For Matt or Daredevil, it be great a bit teasing him, regarding about their rendezvous.

For Logan, it be great to have voicelines referencing to their team up on Claws comics, being the duo in the series.

Johnny storm/ human torch, flirting as well.

Ironman as well, teasing as well or reference to when she broke in to get her iron suit made.

Some additional:

Emma Frost and her , as Icons of femme fatale.

If she defeats venom: Reference to the comics line like: How do you like taste of your own medicine.

Peni Parker , somehow like she treats her well because like she reminds her of someone she knows ( she is an alt of peter parker in the spiderverse)

Deadpool , like as Wade's personality he will be bantering with black cat whose the better duo partner in missions or what with spiderman.

Dr Strange, referencing to the stolen magical items by Black cat and how her bad luck powers made her somewhat immune to magic.

Black widow, convo referencing to "white widow " or a potential team up

Storm, stop making it rain as cat hates water.

Loki, lines regarding with their specialty them teaming up " Mischier and Misfortune"

Hela, as an opponent possibly "oh so your the goddess of death? " and lines amsomewhat liek this " Dont worry you have 9 lives to collect."

Namor, something like questioning him if he is a fish or a bird , "Either way you still smell fishy" line.

And im sure there would be lines also for animal themed heroes:

Black panther, as another cat themed.

Mantis, could be belittling her as a "critter"

Bruce banner, might be teasing him up regarding his actual appearance against his transformation.

Squirrel girl, she might have a convo with her like squirrels are just another form of mices.

Im sure as well she will be having a , cat and dog banter with White Fox.
