She's not sure if she wants to be offensive or defensive, and kinda sucks at both. Her only real purpose for existing is "the story is kinda cute."

Base version isn't great either.

She has a stupidly big HP pool, but otherwise her stats are more 2½ star than 3 star. Combine that with a decidedly average smoke grenade and terrible tiles, and you end up with a doll more bland than Foster's. Can be made work if you really want to (give her plenty of evasive buffs), but you're almost guaranteed to be better off with UMP45 if you want smokes.

If for some reason you absolutely must have a 2 star Molotov. You get Skorpion for free really early so she doesn't see much use (though she does slightly outdamage skorpion). Has not great dodge and okay HP. She does however come with an adorable as hell Children's day skin so I wont entirely fault you for wanting to bring it.

Ablative armor and a grenade. Has a lot of HP for her rarity with a not so terrible evade, though YMMV between her and M38. Her main virtue is that she's the first 3 star you get from the story and they give you a pile of her so it's easy to stock up bodies. Only useful for logistics and cores once you have real tanks. If you happen across free PPS-43s, they're somewhat better.

Has a mod, but it's not great either.
