Mk.99 is the only surviving combat android unit at Heavenhold ever since they were mostly disposed of.
Combat androids were designed to support the Heroes defending Heavenhold. They can instantly exhaust their remaining power to commence heavy artillery strikes against the enemy. They are capable of free-flight but tend to avoid it at other locations except for Heavenhold to conserve power. Even their self-charging units can't meet the power demand. They have the least restrictions on their behavioral software, which enables them to make active decisions compared to worker androids.
After Mk.2. one of the combat android units deployed by Heavenhold in the past, became corrupt and threatened Heavenhold's safety, Android Association decided to dispose of all units and also stop the production. Mk.99. the youngest and the lowest rank among her fellow combat androids, was considered a 'B-tier unit and became excluded from disposal. The Android Association finally woke her up from her long slumber after judging they can't defend Heavenhold with Just the Heros. Mk 99 may not be up to the specs of the combat androids from the past, but she is definitely the only one left.
When Mk.99 was awakened, all Heavenhold's androids were programmed with the Three Laws of Androids to prevent another Mk .2 fiasco.
- First, an android may not harm Heavenhold or, through Inaction, allow it to come to harm
- Second, an android may ignore orders except where such orders would conflict with the First Law.
- Third, an android must protect the owner of the Champion's Sword as long as such protection does not conflict with the First or Second Law.
Android Association expected the Second Law to give individuality to each android, but somehow they all ended up with 'lazy and dodging work as much as possible' personalities. Mk.99 was famous among androids for having the easiest job because she did not have to wake up at all until Heavenhold's emergency protocol level 9 was in effect.

Suggested Weapon
Omega BlasterHer EX weapon is best as you would expect as it increases her range and damage.
OR
Magiton BusterA light rifle that is compatible with her chain and allows her to do higher damage than other alternatives.
OR
Turbo Power RifleThe next best thing to Magiton Buster, as it grants her the matching element bonus and is compatible with her chain but has slightly lower damage output.
OR
Blue RoseAny rifle that is an exclusive weapon for anyone can be used on her to make her match the element of her team for raid. This includes Blue Rose, Genocide, Terminator, Trouble Maker, and Cosmic Destroyer for their respective elements.
Suggested Accessory
Minotaur’s NecklaceHas all the stats she needs to maximize her damage potential, such as Atk, Crit Hit Chance, Skill Damage and Weapon Skill Regen Speed.
OR
Sharp ShooterGives the Crit Hit Chance she needs to amplify her burst damage, and is really accessible.
OR
Mirror Earring of FaithHas all stats but Crit Hit Chance that she's looking for and makes her tankier, but is difficult to roll good stats on.
OR
Ring of BeliefHas Crit Chance, Atk, and Skill Damage plus decent defensive stats which makes her versatile.
OR
Honor RingHas high Atk and is a bit more defensive than some of the alternatives, but lacks many other beneficial stats. The Atk Decrease negation is only good situationally, but can help her fight some heroes in arena such as Bianca.
OR
Earth NecklaceMostly an arena pick. It has very low offensive stats, but is one of the most defensive options available and comes with the unique stat, Def Decrease Negation, which makes fighting many units much easier in arena.
Suggested Cards
2x Crit Hit ChanceBest option to amplify her burst damage. Supplement with an Atk card if you only have one Crit Hit Chance card.
OR
2x AtkA good offensive choice if you want lower but more consistent damage, or if you don't have Crit Hit Chance cards. Ideally the "Extremely Salty Pasta" if you have it due to its higher Atk than other cards.
OR
1x Atk, 1x DefA good option if you're dying in arena when using her, and need a little boost to survivability.

Update: JP Illustration was reveal and she will be voiced by Yui Ishikawa, who also voiced Enterprise, 2B, Mikasa Ackerman, etc.
gelowned#6474
i was wondering why she sounded like lucia from pgr
now i like her even more
gelowned#6474
speaking of which whats with her and robot girls
And3rFive
¿Cuál sería el mejor producto para MK-99? Estoy mejorandola, pero no se que ponerle ;-;.
Nachin
De momento tengo solo azules y grises para ese espacio por lo que el item podría cambiar en morados, yo le puse la moto que le da defensa y atk luminoso, es la que mejor stats le da, si me cae alguno que mejore atk y crítico sería lo ideal pero no he tenido suerte farmeando.
Cain
So whats the real score ?
SIN
Make her score 99 at this point…who you are kidding she is 10 in both arena and Colo but 9.5 in pve ..
Make it 99 so it matches her name because she epitomey of meta….only counter being Sohee and that’s 50\50…I don’t think we can get more op than this.
thisisinaccuratelol
How is she a 98? Is that a placeholder ranking?
Eclipse
She’s very good in colosseum so the 10 rating there isn’t much of a surprise. In arena she just does so much damage and with her Beam Cannon attack shooting through walls and having a very long range, even if she loses, you can bet her opponent is half health at least(unless it’s a tank). I don’t think the 10 rating there is right though it should be at least a 9, but not a 10. PVE is self explanatory.
Diana
My korean mk99 would like to say hahahahahahaha.
(sometimes game breaks her and she doesn’t attack when she’s cornered)
Leona
Does anyone know which accessory is best for her?
Eclipse
Minotaur’s Necklace. Or if you don’t have it, Sharpshooter is always a great option for a DPS character.
Spase
i dont agree with PVE rating. should be atlest 9.25. in my experience, even with a little bit of stat disadvantage she does equal or even better then Tinia or Mayreel who are 9,25 PVE
Spase
lmao it actually changed
Geralt
Updates the rating please, really need Heavenshold rating for the latest hero or alas MK-99 and Lilith since you are my benchmark from the beginning :/
thisisinaccuratelol
With how things have been looking the past month and what we know of in terms of future units (seaside sohee) I’d definitely say a high B to low A for Mk 99.
Pros:
First off, good AI in colo. Hangs back, uses her charged shot often which absolutely chunks damage.
Piercing charged shot penetrates to backline, which is usually squishier.
Piercing charged shot makes her good on a lot of arena maps. Main problem with a lot of rangers is being cockblocked by walls, which Mk 99 bypasses.
Easy to build. Sharpshooter is BiS accessory, allows to you to use your mirror accessories on other units. Easy to limit break for that extra crit boost.
Great damage. Charged shot has great dps, can crit, and pierces.
Not entirely useless close up. Nat 5 passive lets her get away with more than a ranged unit usually could in terms of close combat.
One of the most highest damaging chain skills in the game.
Ranged attack party buff. This is both a pro and a con.
Pairs extremely well with Gabriel. So much so that I might even say that this could count as a con for other people. Gabriel provides everything she needs, and still is relevant in the meta.
Cons:
Ranged units in general are squishy. While her nat 5 passive helps, she’ll still die quickly to melee and even more so to ranged. Sharpshooter being on the lower end of def does not help.
When she can’t pierce targets in colo she becomes less of a viable option. While this isn’t a problem usually, if a tank distracts her and forces her to use the burst mode option, she becomes more of a liability than an asset in colo.
Dependent on crits.
Not universally versatile like a Gabriel in terms of party buff. Mk 99 is ranged.
Charged shot heavy playstyle in certain arena maps will make her less viable (but this applies to every hero).
Overall a great unit that has seen much use in colo where she is really goddamn annoying, and in arena. Honestly not sure on kamazone usage, but I do not see her having any impact on orbital lift. PvE wise, she is pretty good. Recent worlds have all been dark, giving her a type advantage,
However, for colo and arena, there is a new basic unit coming out, seaside sohee. Not entirely sure if she’lll have any impact yet, but the type advantage may be enough to push certain light characters like mk 99 out of the meta.
Pocai
You should post this in the discord of the page https://discord.gg/KDgQgVM
Spase
as we can see she is not low A or high B
ok nerd
Android girl with LEG and a bopping character theme
NICEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE~
meninzera
Is she better or at least close to Nari?
I only have Nari cause of Garam, but my Nari is super weak…
I was thinking of replacing her for Android Mk.99
Geneade
She’s like a micro-nari. In colosseum she did 70k damage to an offensive team when she was on a team with FP and Oghma. (The highest dps output from the other team was only 20k)
meninzera
Quite interesting. But what do you mean by micro-nari?
Geneade
A lesser Nari
Natzuki
Does anyone remember Eva? No?
A player
Honestly, it doesn’t matter if this hero is bad or not, it’s genuinely fun manually playing this character.
Leona
I have 300 mileage, and enough gems to summon it, but I have an existential question, which ex weapon is better? Gabriel’s or Android’s?
Geralt
depends on your team build but yeah both versatile atm
I wasn’t expecting another new hero so soon.
Nikurasu
I wonder what happens if Beth and Mk is on the team? I mean Beth has Melee buff, it might be able to support Mk’s chain skill, cause it deals melee. While Mk has Range buff that can support Beth’s Chain skill. Plus they have opposite Chain trigger.
Nikurasu
Oh wait, i was wrong with chain trigger part…
Cabbage
Rip again to the mono dark teams.
They just did this one so that Nari was not necessary in every team
Mike
But what if Nari is on the team? With Future Knight? O. M. G.
Cabbage
then enjoy your massacre 😀
pler
i guess they r trying to balancing melle vs range meta
