'''Parapluie''' ([paʁaplyi], French for "umbrella", 伞病毒 in the original script) is a computer virus built around the [[OGAS]] core data. Designed by [[Paradeus]], it has been used during the [[Butterfly Incident]] in 2061, and later by [[Sangvis Ferri]] against [[Griffin & Kryuger]] as part of '''Plan Parapluie'''.

Multiple types of Parapluie have been used to different ends, with their common feature being the implantation of an OGAS construct in the infected [[Neural Cloud]]. Elite T-Dolls infected by Parapluie include {{doll name|M4A1|AR|4}}, {{doll name|UMP45|SMG|4}}, {{doll name|ST AR-15|AR|4}} and {{doll name|M16A1|AR|4}}. [[16LAB]] has successfully developed countermeasures against Parapluie.

The original form of Parapluie is a compressed form of the source code of [[OGAS]]. Once implanted into a host [[Neural Cloud]], it overwrites its operating system into an OGAS system. If the massive computational load can’t be processed by the host, its Neural Cloud will suffer irrecoverable damage.<ref name=SC51 />

Parapluie was first used on mature cybernetic clones by [[Paradeus]] at their Paldiski Submarine Base labs to implant their biological Neural Cloud with OGAS. Those who could not support the process suffered brain damage and were discarded as [[Isomer (Enemy)|Isomers]], sent to Tallinn by train and used for [[Epiphyllum]] experiments.<ref name=SC51 /><ref>{{cite|gfl|sc|Subsurface Homecoming II}}</ref> Successful subjects became [[Nyto]]s, and outstanding successes received their own name like {{enemy name|Nimogen|boss}} and {{enemy name|Mercurows|boss}}.<ref name=C121 />

In [[Tactical Doll]]s, the OGAS payload will cause a fatal overload in low-spec Dolls<ref name=SC51>{{cite|gfl|sc|A Rock and Hard Place}}</ref> as a side effect of the implantation,<ref>{{cite|gfl|sc|Subsurface Homecoming III}}</ref> or can provoke a neural cascade when the consciousness tries to take over by force. These are the normal outcomes for a doll infected with Parapluie.<ref name=GF2BB19>{{cite|gfl2|[[Breaking Butterfly]] LA1-9}}</ref> However, if the Neural Cloud is short on space or the OGAS fails to develop its own personality, its spawn instance will be absorbed by the host and remain in Level III.<ref name=C121 /> If the original Parapluie instance encounters a run error, the base Parapluie program will release the instance from its control and issue a new spawn instance to continue the rewrite process. Called the “binary mechanism”, this feature is very obscure since the virus is nearly always quick enough to either complete the rewrite or cause the host's destruction.<ref name=GF2BB19/>

This strain of Parapluie causes the infected Dolls to go in a berserk rage before eventually being destroyed by neural cascade.<ref>{{cite|gfl|pl|Foam Stabilization I}}</ref> It was used during the [[Butterfly Incident]] in order to kill [[Lycoris]] and enable {{enemy name|Elisa|boss}}'s growth.<ref name=C134 /><ref>{{cite|gfl|13-5}}</ref> [[William]] prepared two T-Dolls equipped with backdoors, the main unit {{doll name|UMP40|SMG|4}} and the backup {{doll name|UMP45|SMG|4}},<ref>{{cite|gfl|dd|3-1, Audio File 1}}</ref> and arranged for their deployment during Operation Butterfly. UMP40 successfully deployed the virus, but shielded UMP45 from infection and ensured her survival.<ref>{{cite|gfl|dd|3-4, Audio File 16 through 19}}</ref><ref name=SC54 />

{{doll name|M16A1|AR|4}} resisted Parapluie for longer because she was created using a human brain as a template. However, she was still a prototype and needed Elisa's help to survive neural cascade.<ref name=C134 /> Parapluie remained embedded in her systems and eventually spread to other members of [[AR Team]].<ref name=SC54>{{cite|gfl|sc|All-Devouring Sea of Flowers}}</ref> Due to her Neural Cloud being closest to her human model after her personality limiters were lifted by [[Persica]],<ref>{{cite|gfl|8-4E}}</ref> {{doll name|M4A1|AR|4}} was unaffected by Parapluie and her OGAS consciousness developed unhindered.<ref name=C134>{{cite|gfl|13-4}}</ref> [[Persica]] designed the neural clouds of {{doll name|M4 SOPMOD II|AR|5|costume=costume1}} and {{doll name|RO635|SMG|5}} with strong firewall defenses against incoming OGAS format data, causing a complete system crash in case the dataflow becomes too heavy to defend against. This made them impervious to Parapluie infection.<ref name=C121>{{cite|gfl|12-1}}</ref> {{doll name|ST AR-15|AR|4}}'s infection was revealed during Plan Parapluie, but its growth was halted when she sealed her external ports.<ref name=SC41>{{cite|gfl|sc|Infinite Connections}}</ref>

 

Griffin first learned about Parapluie through the intel recovered by [[AR Team]] in Safe House 3,<ref>{{cite|gfl|5-1}}</ref> but the virus in AR-15 was used to locate Griffin's secret base and stage an attack to kill [[Berezovich Kryuger]], as the Griffin high command was meeting to organize a strategy against Plan Parapluie.<ref name=C56 /> AR-15 was discovered to be the source of the leak due to increased data traffic and Griffin detained her.<ref>{{cite|gfl|5-4}}</ref> AR-15 decided to turn the virus against Sangvis Ferri, deactivated all her communication modules to stop its spread and escaped Griffin's custody<ref name=C56>{{cite|gfl|5-6}}</ref> to infiltrate Sangvis databases with the authorizations granted by the virus' presence and find intel about its design,<ref>{{cite|gfl|6-3E}}</ref> which she left in external storages for Griffin to recover.<ref>{{cite|gfl|5-4E}}</ref>

 

Five days after the attack, Griffin deployed [[Squad 404]] against a signal jammer suspected to have been installed for Plan Parapluie in Area S06, but the jammer was an infected decoy<ref>{{cite|gfl|c|1-4}}</ref> meant for Griffin units, and {{doll name|UMP45|SMG|4}} was infected with a dormant form of Parapluie.<ref>{{cite|gfl|dd|2-3}}</ref> As AR-15 was roaming Area S08 for intel, {{enemy name|Dreamer|boss}} leaked information about a server site to direct her to a specific terminal and install a jamming module in her system,<ref>{{cite|gfl|7-2E}}</ref> creating a large signal jamming area and slowing Griffin's advance into Sangvis territory.<ref>{{cite|gfl|6-5}}</ref> AR-15 was declared KIA after she blew up the building containing her and one of Elisa's dummies, but she was saved by [[Task Force DEFY]]. After this, she kept all her digital transmission modules deactivated in order to contain Parapluie, preventing her the use of the Zener network to control [[Dummy Network|dummies]] and exchange data, relying only on analog radio for long-range voice transmission.<ref>{{cite|gfl|sg|Starting Point}}</ref> Though her infection had been too mild to take over her neural cloud, her prime directive of protecting {{doll name|M4A1|AR|4}} had been destroyed.<ref>{{cite|gfl|sg|2-B Castling I}}</ref>

 

{{doll name|AUG|AR|5}} of {{doll name|IWS 2000|RF|5}}'s squad subjected herself to Parapluie during a mission by using an infected SF communication relay, in order to warn [[the Commander]] of an inbound biological weapon unwittingly carried on their clothes by T-Dolls returning to the base. She was destroyed by IWS shortly after being overtaken.<ref name=C84N />

 

In the aftermath of the Area S08 battle, AR Team and all T-Dolls suspected of being infected were quarantined in Area S05 for further screening as [[16LAB]] established countermeasures against Parapluie.<ref>{{cite|gfl|7-1}}</ref><ref>{{cite|gfl|7-3}}</ref> The first T-Doll known for carrying such countermeasures is {{doll name|RO635|SMG|5}}, who could detect Parapluie-infected terminals by sensing the pattern of the virus remote control signal and neutralize it before accessing the terminal,<ref name=AW14 /> as well as perform local counter-jamming.<ref>{{cite|gfl|8-1}}</ref> Much like AR-15, 16LAB also used the virus as a mean to infiltrate Sangvis Ferri networks. This modified strain was used by {{doll name|M16A1|AR|4}} to access top secret files at Sangvis's Base 0 and help stabilize M4A1's neural cloud after her encounter with Elisa, but in doing so she subjected herself to an unrepairable amount of the virus and her neural cloud was claimed as overwritten by Sangvis Ferri.<ref>{{cite|gfl|8-3E}}</ref> This was however part of her plan to join Sangvis Ferri willingly.<ref>{{cite|gfl|ct|Safe House}}</ref> {{enemy name|M16A1 (Boss)|boss|alt=M16A1}} later appeared to fight against Griffin, saying she was glad she could use her capacities to their fullest after breaking free of the limitations of human control.<ref>{{cite|gfl|sg|End Game}}</ref>

 

 

At the same time, Squad 404 was deployed to recover the data extracted by M16A1, but the Parapluie virus planted into UMP45 a year prior betrayed their presence to Dreamer and {{enemy name|Destroyer|boss}}.<ref>{{cite|gfl|dd|2-1}}</ref> Sending Destroyer close enough to connect with UMP45's virus, Dreamer relayed Elisa's general order to convert her neural cloud. However, none had predicted that UMP45, as an old Sangvis Ferri electronic warfare T-Doll, was able to swap her neural cloud from Zener to OGAS protocol, interrupting Parapluie's effects. Moreover, this enabled her to tap into Sangvis Ferri's resources to counter their own virus as long as she used the OGAS protocol. Realizing the situation, Dreamer opted to use Parapluie's command authorizations to melt UMP45's neural cloud with Sangvis' offensive firewalls. UMP45 was narrowly able to survive by disconnecting her neural cloud.<ref>{{cite|gfl|dd|2-4}}</ref> An OGAS consciousness briefly took hold in her Neural Cloud, but it couldn't grow and lingered in her Level III layer, taking the form of 45's memories of UMP40.<ref name=SC51 /><ref>{{cite|gfl|pl|Molding}}</ref> 45 met the Parapluie persona during emergency maintenance after the [[Great Retreat]] and confirmed it had become harmless.<ref>{{cite|gfl|[[UMP45]]'s Neural Upgrade story 3}}</ref> 45 asked [[Persica]] to extract it from her Level III into her Level II and promote her into a secondary computation core, despite the risk of it resuming its rewriting protocols one day.<ref>{{cite|gfl2|[[Breaking Butterfly]] LA-1-6}}</ref>

 

After the military's retreat and the disappearance of their counter-jamming capacities, Parapluie spread into all available networks, jamming transmissions<ref>{{cite|gfl|sg|1-A Stroke Dead Center I}}</ref> and taking control of military units left behind<ref name=Singu1C>{{cite|gfl|sg|1-C Re-Ignition II}}</ref> as well as Griffin T-Dolls deep enough in the signal. This forced [[the Commander]] to accept the offer of Task Force DEFY for help in recovering AR Team<ref name=C104E /> and to forbid the use of long-range Zener connections to reduce the chances of infection.<ref>{{cite|gfl|ct|Unknown enemy}}</ref> DEFY relied on {{doll name|AK-12|AR|5}}'s EW capabilities, and to a lesser extent {{doll name|AN-94|AR|5}}'s, to break through the jamming and maintain communications during their operation,<ref>{{cite|gfl|sg|1-A Stroke Dead Center III}}</ref> while the Commander's forces relied on foot messengers like {{doll name|MP7|SMG|5}} to establish transmissions from outside the jamming zone.<ref name=Singu1C /> KCCO's plan to take over Elisa ultimately failed when OGAS performed its own counter-attack and nearly destroyed KCCO's servers.<ref>{{cite|gfl|sg|2-D Minor pieces Draw II}}</ref>

 

 

 

The friendly persona pretended to be attempting to rewrite Leva's neural cloud again to convince [[Lenna]] and [[Persica]] to delete the Parapluie virus from Leva's neural cloud, but Leva saw through her act and searched for a solution that would save the friendly persona she's been living with for a decade. Persica eventually noticed that the friendly persona was no longer part of the virus because of the binary mechanism, and the hostile instance was deleted with no adverse effect.<ref>{{cite|gfl2|[[Breaking Butterfly]] LS-1-5}}</ref><ref name=GF2BB19/> The friendly persona was extracted from Leva's neural cloud and became [[Lainie]].<ref>{{cite|gfl2|[[Breaking Butterfly]] LS-1-6}}</ref>
