With her skill kicking, she deals a fixed amount of bonus damage based on how many enemies show up, and deals bonus damage when she changes targets. The good part is that since it's a fixed amount based on enemy count, the rest of her stats don't matter. Doubly so because it ignores Armor, Evasion, Shields, etc., so she can still be useful while suffering from the stat penalties of using Parachute Fairy.

The Steyr ACR is the gun the Pallet Rifles in EVA are based off of, and this one is about as useful. On one hand, it seems like she'd be good for para fairy and its debuffs (you get +25% final damage with that), except it isn't enough to make up for the debuffs still. It's also not very easy to get debuffed. Evaluation may change based on future enemies, but really it's not worth it when you have so many good ARs to choose from.

Between her two modes AND a passive that helps keep shotguns alive, I don't think there's much more to say other than "she's great, you will probably find a use for her."

With LTLX7000 being out, the main question asked of most shotguns is "are they as good as LTLX?" As for M26-MASS, she does her damn best trying to be. While LTLX has her SUPER dumb damage mitigation in her active skill, M26 has it baked in as a passive. If any damage she takes is 5 or lower, it’s completely ignored, as if she had very good flash rounds. This is applied AFTER armor mitigation AND flash rounds. With flash rounds, she’s essentially immune to anything 8 damage or lower, which is very strong. However, if the enemy does too much damage, this passive does nothing. However, in current day, LS26 exists. This fixes damage taken to 5 which, spoiler, is negated by MASS's skill. Can be very strong to force MASS to tank some insane things. How often will that be used? Eh. It's neat at least.

The one thing she does have going for her with her passive is that she can actually mitigate damage that bypasses armor. You can entirely mitigate stuff like grenades through it. You could sit in gundam range for a bit and not fussed about it. You could even sit in Typhon lasers and be fine. (Depending on firepower of Typhon, please do not attempt without consulting a local doctor)

Overall, she does fall short of LTLX just due to the sheer power of doubling your armor along with 20% DR. The utility of her active also is less relevant compared to LTLX. Removing HP shields and buffs (which get far more common) is stronger than a Molotov and DR to backline. To add to that, the 6 second initial cooldown hampers the effectiveness of the backline portion of the skill. This is because most things that do target the backline would already be skullfucking you at that point. Other cases this is bad include maps M26 shouldn’t be brought to for one reason or another, like when shotguns are bad for it in general or you can’t use machine guns.

A pastiche of fetishes that the game somehow didn't cover before. Behold, armor-destroying big gun brown eyepatch girl. Fixed fire rate that's slightly jank due to how the game handles frame count (shouldn't matter though), and absolutely hates armor. Her skill is passive and her basically permanent 400% damage vs armored enemies lets her shred armored units fairly early on.

Her five second reload time may or may not matter very much, depending on circumstances.

Notably used in data sim setups.

She has an SVD so she's... EXACTLY NOTHING LIKE SVD. She's closer to QBU-88, having an AoE effect, but she has self-buffs on top of that and, in some situations, can match and exceed such DPS staples as M14 Mod. Honestly if you're coming out of the event with only one of the girls (besides Henrietta who you get just for doing story), then it really should be Rico. Also remember that her tarot cards are used up BEFORE the active part goes off, so you don't get the passive benefit for the nukey bits.

She's basically AUG, but without the random fire mechanic. Which makes sense because she has an AUG. This logic doesn't work for any of the other girls, but shush.

If you'd like an evaluation of AUG to get an idea of how good Angelica is, here's AUG's article.

On one hand, she's actually not bad in melee. On the other, she suffers from dumb mechanics (like not being able to switch to melee while reloading, which WOULD HAVE BEEN REALLY NICE). She's not terrible at the role of "melee shotgun" (she's actually quite good at it), but the number of situations where you'd actually want a melee shotgun are quite limited.

The meme potential of a girl with a camera and a smiling face is good enough reason to have her (now that we have multiple secretaries), but she's also not half bad as a combat unit. She gets a shield, and having the shield gives her FP buffs, while losing the shield means she's getting EVA buffs. The uptime is quite good, so she's not a bad side DPS (she has a 69% damage buff at 2 stacks and 119.7% at three stacks) that can sub-in for off-tanking and can even work as a main tank (44% eva at two stacks and 72.8% at 3). The problem is the optimal timing can be a little iffy, but she's alright for AFK fighting since it'll generally be good enough, just not fully optimized. The tradeoff between her and SR-3MP is just uptime vs power.

As expected of the main girl I guess.

Oh, and her tiles are weirdly shaped, but this is not uncommon for off-tank dolls anyway.

Kinda lewd. Her side DPS actually isn't awful, but her ability to tank sucks. Also it's called Jashin-chan Dropkick because she... dropkicks things.

Yes, Pekola, as opposed to a certain dumb rabbit. The eternally-starving once-most-powerful angel. She actually won't attack at all until you meet her conditions of getting enough buffs. Thankfully, stuff like Python's FP buff stacks count as individual buffs. More hilariously, the fairy talent Fervor also counts as three buffs. This makes satisfying the conditions for her skill actually pretty easy.

What you get for doing so is a ridiculous RF that completely ignores enemy armor and shields. A major downside to this though is she wont deal as much damage as another RF if you don't need such capabilities, since she isn't affected by very many damage buffs due to how she works.

This should be obvious, but you should pick up her unique gear if you plan on using her.

Suffers from not only being an MG, but an inconsistent one due to her passive. Her stats are alright, but her passive skill is unreliable, not that it matters much since it only activates on reload. The active suffers from the problem of activating slowly enough that you'd expect MGs to have already killed most of what you'd want to stun anyway.
