As Alyssia and Kuma flew towards Thriller Bark, the Straw Hat Pirates were lured into a trap which ended with many of their shadows being stolen from them.
Many of the shadows had been placed within different corpses that had been preserved and stitched up by Dr Hogback while the Straw Hat Pirates were all placed back near their ship where they would be destined to be unable to live underneath the sun.
After suffering such a big loss, they regrouped themselves and started their counterattack.
By the time that Alyssia and Kuma had arrived, Many things had happened and Kuma went to meet up with Gecko Moria to warn him about the current concerns of the World Government involving the Straw Hat Pirates.
After the defeat of a Warlord of the Sea and the events on Enies Lobby, the World Government were worried about yet another Warlord being defeated at the hands of the Straw Hat Pirates so Kuma was tasked with giving him a warning along with informing him about the current events of the world.
Blackbeard had been given the position as Warlord of the Sea upon defeating Portgas D Ace and capturing him alive and Kuma mentioned his doubts about Blackbeard briefly before changing the subject by telling Moria he was there to help deal with the Straw Hat Pirates.
Kuma was quickly rejected after offering to help Moria and many events followed along the original timeline.
A little time before their meeting, Perona was stealing the treasure on the ships while attempting to flee Thriller Bark after being defeated by Usopp but she ran into Nami who attempted to stop her and take the treasure for herself.
However their interaction did not last long as Kuma appeared behind her and briefly asked where she would like to go on a vacation which was followed him appearing before her and slapping down upon her.
Alyssia was hidden behind Kuma's big body during the whole encounter and as Kuma appeared before Perona when she was about to attack him, Alyssia had disappeared upon using her full strength as she flash stepped to Perona and cut her slightly with the nail on her finger while another hand grabbed a strand of hair from her head which had extracted a small amount of blood and hair to be collected as a Paramecia type Ghost Devil Fruit sample and to collect certain unique features in Perona's Lineage Factor whether it be her body type, pink hair colour or her eye shape and colour.
In the split second that Kuma had moved, Alyssia had quickly gained everything she needed before Perona was hit by Kuma's palm and sent away without anyone noticing her even being there as she used others or buildings as cover to hide herself so the Zombies and Nami did not notice that she was even there.
Alyssia appeared far away and took out a vial as she dropped the blood on her nail inside before sealing it while doing the same with the strand of hair.
As for Perona, as she was sent flying she had been confused how she had suddenly been scratched so she had no other person to blame but Kuma who had sent her away.
During the time that the Straw Hat Pirates were being kept busy with Oars and Kuma was talking to Moria, Alyssia infiltrated the castle while avoiding the many traps within and the watchful eyes of the many things that had been given shadows to give them life.
She arrived inside the wedding chapel and found the already beaten Absalom who was still unconscious so she started gathering some samples from him which were very helpful considering his race or tribe which would be helpful towards her Lineage Factor research.
However the most important part was the Paramecia type Invisibility Devil Fruit inside his body so she quickly took her samples and stored them away safely.
She made sure to visit other places where battles had taken place since she had hoped to gain more but upon arriving in one location where Zoro and Ryuma's corpse fought but she only found a little bit of the ash that had been left behind so she collected that before moving onwards.
Alyssia later arrived at the place where Dr Hogback had fallen and had been stepped on by Oars, he was found in a critical condition with many broken bones while he remained in a coma nearing the edge of death so Alyssia took him to the side and tried her best to stabilise him.
Fearing that she would lose him too early, she started updating her system skills from Dr Hogback and purchased what she could with the points she had built up since returning to Rica Island from Water Seven and St. Poplar so she was able to extract a lot of Dr Hogbacks skills including his medical knowledge which could help with her research but also be given to help Tristan improve.
Tristan had remained on St. Poplar with many of medical team under her as they continued to keep their medical practice open while providing many types of medicines or cosmetics to the White Storm merchants so her overall skill as a doctor had risen with all of the opportunities she had been given but Dr Hogback was a famous doctor who Chopper had greatly admired until a little while ago because of his horrible nature.
Although many of his pursuits and his personality were to be doubted, his talents and ability as a doctor were not so even if he died sometime soon, Alyssia wished to get every last bit of knowledge from him before his death whether it be medicine based, the human body and surgery or other techniques like how he was able to create many types of zombies even if she did not wish to cut up body parts and out them together to form a new body.
Alyssia did not wish to go down the route of Dr Frankenstein or Dr Hogback where they create monstrosities from corpses but some of the methods used could be helpful in other areas.
In another part of Thriller Bark, the battle between Gecko Moria who was inside Oars was coming to come to an end as Oars was defeated but after Alyssia had collected what she needed, Doctor Hogback had passed away so she went around collecting samples from the zombies that were lying around the area.
Alyssia appeared to extract several samples from the preserved corpse of Oars when everyone was distracted with the final battle with Moria.
Moria devoured many shadows and gained a large boost in power but could not hold onto that power as Luffy continued to attack his stomach which made him open his mouth.
Eventually Moria was defeated and crushed before Kuma appeared to start the next confrontation when Luffy was no longer able to fight which turned many eyes to him and away from Moria so she had appeared over his body and started taking samples from him.
As Alyssia gained some distance away from them and thought to herself. 'Moria has such a unique body shape and overall look.. not to mention his pale skin, ear shape, sharp teeth and horns so this will be very useful for my Lineage Factor research. I have gained so much whether it be from the many corpses, Moria, Absalom or Oars for differing races or human forms but most importantly I have acquired three more Devil Fruit samples which each have their own unique characteristics and uses. Now I just have to wait for the next events to happen..'
It did not take long before there was a massive explosion of air which defeated many others after they refused to hand over Luffy's head to save their own lives.
Zoro and Sanji both offered their heads in place of their captains but Zoro knocked Sanji unconscious before taking on Kuma's trial where he had to endure hellish pain.
While many were unable to stay awake after the attack from Kuma, Alyssia arrived and started taking samples of many people who were laying on the ground before disappearing once more without being seen.
She lifted a bag full of different vials which had name tags on them and some minor descriptions then she played with one that was in her hand. 'Charlotte Lola. Born with a twin sister from Charlotte Linlin or Big Mom, although she did not inherit her mothers or fathers large build or monstrous strength, she still has some potential. However what I want from her is not just that but what is hidden deep within her Lineage Factor from her mothers side. At a young age, she was able to kill a giant during one of her episodes and display horrifying strength and endurance before becoming a member of the Rocks Pirates then rose to become an Emperor so her Lineage Factor is difficult to obtain. Some understanding can be gained from the samples collected from Lola.'
She had gained more than enough so she quickly met with Kuma who had sent her flying towards Rica Island once more.
As she arrived there, she started to arrange her newly acquired samples while updating the overall data that she had gathered with the help from the system which she then started passing on to K1 to remember while she got someone to work with K1 to write everything down from Dr Hogback to send to Tristan to study.
Not a very long time had passed as everything returned to the normal routine for everyone within the White Storm but the world was slowly drifting towards war as the Marines and World Government were preparing for war against Whitebeard.
The Pacifista were completed and Kuma was almost out of time before he had to undergo the final operation so it would not be long until certain events take place as the Worst Generation enter Sabaody.
From her contacts within the underworld by the name of number one, two and three there was an increase in ability to locate more secretive auctions which allowed her to get her hands upon many types of slaves of different races ranging from Long Legged, Long Armed, Long Neck, Black Wing, Horned or many other types of races or tribes so she was able to shorten the list of what samples she still required while she still missed some more difficult to obtain ones like the Oni, One Eye or Lunarian race along with the many within the New World that can easily he found within Big Mom's children's bloodline.
In the meantime, Alyssia continued to work on several things along with getting a team to work on the Arc Maxim in secret to help with her future plans that would help her benefit even more from the events of the world.
