Operator Overview
"If anything breaks, I can just make another one!"
Busy-body inventor and one-person army, Mayer is a Summoner Supporter Operator who can stall enemies and provide large amounts of on-demand Arts damage nearly anywhere on the map.
Mayer’s playstyle revolves around her unique trait, which allows the placement of ‘Robotters’, which she calls her Meeboos. Robotters act like melee Operators, can block 1 enemy, have decent HP, and decrease the ASPD of enemies that engage them. Robotters count toward the Deploy Limit, and are restricted in the number that can be deployed, which increases as Mayer receives Elite promotions.
Mayer’s first Skill, Bionic Device, passively increases the Physical and Arts dodge chance of deployed Robotters. Although heavy investment into Bionic Device allows Meeboos to extend this buff to nearby allies, and can be stacked with other dodge buffs, this Skill is primarily a stalling tool. It is Mayer’s second Skill, Detonate and Recycle, that is the game-changer. Detonate and Recycle self-destructs all deployed Robotters and deals massive AoE Arts damage, briefly stuns surviving enemies, and ‘recycles’ all detonated Robotters. This allows them to function not only as strategic low-cost blockers, but also as nuclear Arts bombs that can bring pinpoint mass destruction to almost anywhere on the map.The recycling functionality enables rapid redeployment for quick alteration or reconstruction of defensive lines.
By design, Mayer as a standalone Operator is underwhelming due to her very low stats. However, with skillful utilization and placement of each Robotter, Mayer can be a one-woman wrecking crew and even single-handedly clear missions. Learning and experimenting with Mayer’s capabilities will be well worth the time spent with this uniquely versatile Operator.
Elite Promotion Discussion
Another Operator whose Talent is core to their mechanics. The number of Meebos that her talent Robotter allows to be deployed increases from 4 to 5, a significant increase if you want to use this one-woman-army to her fullest potential.
Base Skill Analysis
Mayer gains her second RIIC Skill at E2.
If you are planning on using this niche Operator at her full potential, then you will need to E2 her eventually. The Skill she gains is the best non-specialized buff for the Factory. Since Factory buffs are always in demand, it will be a nice addition.

Profile
Mayer was born in Columbia and was a member of the Rhine Lab Research Lab. She is the inventor of the "Meeboo" wire control system. She is outstandingly capable and runs her own workshop called "Lutra." She is currently working with Rhodes Islands to provide assistance with construction, planning, and development.
Clinical Analysis
Increase Trust to 25.Imaging tests reveal clear, normal outlines of internal organs, and no abnormal shadows have been detected. Originium granules have not been detected in the circulatory system and there is no sign of infection. At this time, this Operator is believed to be non-infected.
[Cell-Originium Fusion Rate] 0%
Operator shows no signs of infection at this time.
[Blood Crystal Density] 0.12u/L
Operator has been in long-term contact with Originium and frequently works to process it. However, due to strict adherence to safety protocols, Operator has not yet displayed any signs of Oripathy.

Archive File 1
Increase Trust to 50.Mayer frequently encountered Silence at Rhine headquarters since she was responsible for preparing, installing, and commissioning experimental devices for her. This was up until Silence abruptly disappeared which in turn caused this project to be terminated. Mayer often feels a sense of regret when reminded of this instance but had she known the true goal of the project, she would have pulled the plug herself.
Archive File 2
Increase Trust to 100.Mayer possesses just the right mixture of a scientist's meticulous thinking and an engineer's hands-on mentality. If there's any downside to this, it's that she never has enough time. If you don't believe it, take a look in her personal dictionary. The word "idle" is missing.
Archive File 3
Increase Trust to 150.Mayer's head contains a multitude of, shall we say, volatile ideas, which makes it no surprise when she creates something eccentric. Out of her countless inventions, her prized and most cherished "masterpiece" is "Meeboo." Mayer diligently creates nameplates for each individual "Meeboo" and carefully cleans up its wreckage after it's served its purpose. It is clear that she pours her heart and soul into the maintenance and operation of each Meeboo, despite their mechanical origins.
Archive File 4
Increase Trust to 200.Since Meeboos take up so much space, Mayer's workshop is extremely cramped, causing her to devise ways to expand it. Despite having a room twice as large as anyone else's, she has managed to run out of space after increasing Meeboo production. Mayer has begged the Doctor to increase her room's size. That request was denied by the logistics department out of fairness towards others. Despite this ban on room expansion, the Doctor nonetheless granted her extra space in the hangar to allow her to continue the production of her Meeboos.
Promotion Record
Upgrade to Elite LV2.So far, a total of 80 Meeboos have been constructed by Mayer. 20 of them are serving in Mayer's squad, while the others have been disassembled for various reasons. All available components have been installed on these models in service and are uniquely named by Mayer on their respective nameplates. Of the 20 Meeboos in service, there remains a single one with an unknown serial number that Mayer uses both as a mobile workbench and an experimental prototype. Despite its advanced functions, it is unarmed and useless for combat.

| Appointed as Assistant | Structural design, industrial R&D, scientific research. You name it, and I can do it, Doctor. |

| Talk 1 | The Engineering Department never approve my proposals. Do they have any bias toward me? What should I do... Right! Doctor, would you please submit this suggestion on improvement for me? It's a deal then! |
| Talk 2 | There are many workshops like mine in Rhine Lab, but what takes others six weeks to finish, I can have it done in one. I'm not boasting! |
| Talk 3 | DO NOT interrupt me when I'm doing my research, or you'll have my Meeboos on your ass! And me! |
| Talk after Promotion 1 | At night I'm always full of inspiration... and the urgency to sleep! No... I can't bear it... Where's the pillow... I need to rest... |
| Talk after Promotion 2 | Hm? Why are these cuties called Meeboos? That's because they go "meeee-boooo" when they boot up. So I named them after that. Fitting, don't you think? Just listen and you'll get it. You press this switch to... WHUAH?! Wrong one! That's the self-destruct button! Oh shoot, run awaaaaaay! |
| Talk after Trust Increase 1 | That girl who just passed by... that was Silence, right? If only then... Oh, sorry, the non-disclosure agreement is still in effect. I should keep my mouth shut. |
| Talk after Trust Increase 2 | I feel kinda empty when I've got nothing to do... I guess that's just how engineers are. You know how that's like, right, Doctor? Huh? You don't? |
| Talk after Trust Increase 3 | Doctor, may I request... No! Not 10 square meters! I asked too much last time, so this time... all I need is 3 square meters! Don't... Don't you leave, Doctor! Even 1 square meter for my research will do! Please! |
| Idle | Geez... where's the coffeemaker... Oh, there it is... You want some too, Doctor? |
