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.

Lower rarity Vector. Has useful evade. Has shit for HP though and lower atk. Can off-tank alright and her molotov is still good enough to use, but you really want better SMGs. Her primary virtue is that you're given a pile of her at the very start.
