One of the deadliest assassins in the DC world, a highly-skilled fighter and trained acrobat who dips her fingernails in poison, Cheshire contains plenty of links to Arrow, although would've perhaps made more sense before the events towards the end of last season. Thats because a major part of her story involves meeting Roy Harper, and the two fall in love, and even have a child together. Obviously thats not likely to come into play now, but she could still feature. She has been an ally to various DC villains, and one of the most notable is Deathstroke. Although he hasnt mentioned her before now, it is still possible that she shows up in Starling looking for revenge for him, or in an attempt to have him freed.
