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.

Another of those HGs that buff based on leadership position, with the Squad Lead getting an alright shield and everyone else getting an FP boost (as opposed to P22 which is positional based). Sometimes you might need that mix. If you do, there you go. Else, she's basically a slightly off-brand P22.

Her Mod 3 unique equip is alright. It lets her punch through lighter armors, and otherwise is excellent at finishing off weakened enemies, rather than wasting full-power shots on them. This is usually a thing with rifles that don't quite instantly giblet their foes. Her tile buffs are pretty okay.

She's alright but not a priority.

She actually gets some fairly hefty stat increases in her mod, with Mod 2 hitting as much FP as M2HB. The issues that 2 stars normally face (low skill values compared to higher ones, etc.) are pretty solved thanks to being upgraded to a 4 star, and it also gives her extra base ammo which helps out a lot. Overall a cheap mod to get, and honestly you get a fair bit of value off even just Mod 1.

She's pretty much an all-rounder MG, and with the Mod 2 skill, technically you're not limited to just SGs, but uh... the shield values are so low otherwise that it only really helps armored things, though I guess some people might find a use for that anyway. MATH BIT: Her Special Equip actually isn't awful, but tbh you're better off with an EOTech in most cases.

Her original form can be found here.

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.

The weirdo, mildly creepy sweet potato. Honestly one of Waterkuma's better designs too. All sorts of adorable and frankly, the best shields you can get. Full party, 42-point shields, with stat buffs if the shield survives. The big thing is she can shield the whole echelon unconditionally, which helps massively for certain attacks like Doppel missile swarms, and can even negate them entirely with a bit of luck, or if you're using FP debuffers. As a result, she's a vital component of many weird teams purpose-built to kill some cheese enemies.

Farm your damned boxes and get her.
