Her skill is kinda neat, but ultimately, you're not going to get much mileage out of making 2~3* dolls better. Cool tiles though, I guess.

3* equivalent of Colt SAA. Useful if you're short on REAL AMERICAN GUNS, but given that SAA is easier to get, probably more a trophy raifu.

The doll is basically Spitfire with slightly different buff tile layout/focus (less FP, more Acc). Frankly, she's really boring statwise and enemy RoF reduction is usually worse than FP reduction (which is good for armor/shield tanking) or acc reduction (Which is good for Eva tanking) and the Spitfire entry has the rest of my thoughts on that.

She thinks of herself as an elite doll, due to the P226's previous adoption by the US Navy SEALs (hence the Seal she has with her) and has a bit of a rivalry with M9, claiming she should absolutely be the more popular one. More info on the notes.

Supernova is a shotgun pretending to be a handgun to go along with her shipmate GSh-18. She’s one of the most supportive shotguns available and she enables some real dumb stuff. You want to use MGs at night? Well, her skill allows for that. Do you need a little more defensive capability for your shotguns? She brings that too, all in a kancolle-flavoured package. Honestly, she’s not an automatic pick on every team. You’re likely going to have to drop a MG in your formation to make use of her fully, which can be an issue.

Her two main draws are her movement speed and her MG buffs. Her roller skates allow her to go almost as fast as a handgun, but not quite. Not much else to say about that, but main reason to take her is the MG buffs she provides.

While crit rate is nice, the accuracy buff she provides to MGs is fixed. This means that MGs are entirely usable at night. It bypasses the accuracy penalty that you would normally have with no PEQ. While not the most relevant thing currently, you definitely want to have Supernova in your back pocket for the future.

She has some of the highest damage and crit buffs in the game, with the best possible tiles ("All around her"), and her skill allows her to override the targeting logic of most other dolls¹, making them focus their fire some, very unlucky fucker (boss if present, otherwise furthest/highest HP/nearest enemy, depending on whether Contender is back/middle/front row). Oh and the skill doesn't wait until impact - the bonuses kicks in as soon as the shot leaves the muzzle. She also can equip AP ammo, which doesn't come up much, but there's a few fights later where this is immensely valuable and if you're using a HG vs armour at night, well... you know. Did I mention she has 40% base crit? She does.

Chinese Makarov clone. Similar job to SPP-1, but less boosting your side's acc and more on lowering the enemy's evade. With fairies now existing she's kinda useless.

One of the more maligned, design-wise, of the Infukun rangers. As a character, she's OK I guess. As a design, she's not as good as the rest of the stuff Infukun made before he left Mica (G11 is peak Infukun). As a unit... she's actually kinda crazy, with a buff for every occasion that makes her one of the best and most flexible T-dolls in the game. Shields for the front, Damage for the back, Acc and Eva for the middle row in case you need that. If you could only get one doll from Isomer from farming, farm this one. Seriously.

If she offends your senses that much, stick a paper bag on her head.

Generally decent buffs esp. at night, and she can be an evasion glass tank (100 evade!) in a pinch. Not bad if you actually kite your pistols but be wary of her limited HP. Honestly, you want a real tank in front still. With her mod, her usefulness continues due to the fairly good buffs she provides.

Her unique expedition equip is decent (even more evasion), but the real draw for it is when you can use it with her other unique equips for the set bonus.

At some point, G&K started running out of real guns and broke out more of the early 20th century guns.

Surprisingly, the dolls with them are actually not godawful.

If she's the leader, she gives a general buff, but whatever, most HGs do that. What makes her interesting is that if she's NOT the squad lead, she buffs the hell out of them, thus making her useful in any formation where you want to pack as much as possible into one doll's ability. Lookin' at you, M4, IWS. (And a few others)
