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.

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.

Props for accuracy. She spends the animoo's story just living in the dorms and only coming out for tests or really weird situations where they cant spare bodies, and she's basically the same in the game - she'll be in your dorms a whole lot. She also has three unique items that affect her passive but otherwise all do the exact same thing. She isn't completely useless, but there's not much reason to pick her over other MGs that don't have finnicky mechanics, because you frankly will not need that many MGs anymore.

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.

AKA SAA - THIS IS THE BEST GUN EV-cough Actually has very nice buffs and a decent skill. Not bad at all in night battles either with the acc up if you have crappy PEQs.

Her mod makes her a stronger pick, and more info can be found on her mod article.

Formerly known as Mk23 SOCOM

Highest damage buff among 4* handguns for awhile. Very good for Bamboo Spears too. KR calls her Champy because of weird meme reasons involving weird manhwa.

Or Stechkin for short. Good RoF buff. Actually combos nicely with other RoF buffs if you need more since her aura shape isn't as weird as Calico's. Works well with IWS. Try to grab her unique equip, it helps.

Has a mod that makes her slightly better.

Decent overall damage buffer with bonus evade for the tank. If you have her exclusive equipment, her buff is a bit more valuable. Nothing super standout though.

+90% Acc Buff aura at 5-links. Also has a +damage up but that's just icing on the weird, underwater-themed cake. With NV equipment, allows you to completely destroy scouts in night battles if you're actually desperate for that. Normally not a buff I recommend, but she actually gives a lot of it so if you're wanting an actual acc buffer, she'll be 1 of the ones you want. Not as important anymore since there will be other sources of acc boost, but... sometimes you might want something?

Yet another CZ75 clone. Mostly just fodder, but she has a +firepower buff skill that isn't super horrible and a +firepower buff-tile that make her usable in an emergency where you somehow need firepower buffers but lack any. %s are passable but not great.

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.

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.

A Britbong copy of Cz-75! ...And kinda weird. She's sort of setup for the 2MG 2SG 1HG thing that doesn't come up much and is defensively oriented, but sometimes it comes up. Just... not on any content currently. Does occasionally see actual use as a result, but she's not going to be your first pick for most jobs.

The problem is that RoF reduction is kinda meh, as while it does reduce enemy DPS, it merely slows down the rate of being shot, as opposed to making shots worse (good for SGs as their armour can more readily absorb it) or less accurate (which helps Eva tanks just not be damaged entirely), making it the weakest of the enemy attack stat debuffs.

Another fucking CZ-75 clone, this time from China. Unfortunately for her, her buffs and skill are all over the place, and most of the time you're better off with a more focused HG – Type-92 gives you a lot more dodge and not significantly lower DPS, Grizzly gives you a whole fucking lot more DPS, Welrod is a better debuffer, etc.

Her damage buff is respectable for a 3* handgun, her tile layout… not so much. The X layout will typically make her excel in a 2SG2MG1HG setup. That setup is very niche and won't come up often. Outside of that, her buff tiles force her into a forward position as main or off tank. She's absolutely not suited for this with her poor HP and evade, and her buffs aren't good enough to really justify it mostly. If youre running and RF HG, you want Calico there usually.
