This post will be the bane of my existence. It's going to be so long I am probably going to grow old and die writing it. Why the fuck do you have to do so much shit Vriska?
So yeah. Vriska Serket. Let's get this over with.
Vriska lives in a large, elaborate mansion near a ton of rocks with her wicked custodian spidermom. Spidermom eats trolls, and chose Vriska to get these trolls for her. So Vriska has to feed her trolls or Spidermom will eat her. The bitch.
[Pictured: Your nightmares for the next three days.]
This is something Vriska can do, as her power is Manipulation. She can force weak-willed trolls to do whatever she pleases.
Also Vriska has 8 eyes. Which is cool.
Her interests include gambling, [F]LARPing, treasure, breaking 8balls, bulding doomsday devices, WINNING, and being the fucking best at everything ever.
When Vriska was very tiny, she found a treasure chest that had magical dice in it, as well as a diary that belonged to her ancestor, Marquise Spinnaret Mindfang. Vriska looked up to Mindfang and wanted to base her life around her, being a badass pirate who does some fucking awesome things. She spends her life emulating Mindfang, going as far as to name her RP character after her.
She started dating both Terezi and Eridan and RPed with them. With Terezi they formed a team called the Scourge Sisters and would feed anyone who lost against them to Vriska's Spidermom.
Eridan had more of a rival role, but Vriska dumped his ass when she felt he wasn't challenging her anymore.
While playing, Vriska seemed to have fallen for Tavros, and wanted to make him a worthy adversary for herself. So, she started to flirt with him. She did this by breaking his legs. PURE GENIUS.
After this Aradia and Terezi both cut off relations with Vriska, and Aradia cursed her to misfortune and being haunted by all the trolls she ever killed. Vriska retaliated by forcing Sollux to kill her. In return, Terezi tricked Vriska into getting her arm and eye blown off, and VRISKA then forced Terezi to go blind. Her neighbor Equius then built her a new robotic arm.
Vriska eventually decided she wanted to be friends with Terezi, Tavros, and Aradia again. She planned to make everything up to them and set things right by commissioning Equius to build Aradia a new robot body. She, unlike many people, knew Aradia was a ghost, and wanted to house her a new body.
She also planned to be on the Blue Team, and she and Equius were going to team up and become the leaders of the team. This fell through when Aradia sent Equius into the medium to save his life, killing Vriska's Spidermom in the process. Aradia told her she was never meant to be on the Blue Team, and that the teams didn't really matter anyway.
Vriska, forced to go on the Red Team, helped Tavros into the game and began flirting with him again, trying to make him a better person. She did this by making his life miserable. She then tricked him into going to her planet, the Land of Maps and Treasure [LoMaT], so she could make out with him.
Tavros was still the same pussy he always was, and Vriska decided to accept that. They teamed up in the game from this point on to find lots of treasure.
Then Aradia beat her to death.
Using her powers from Prospit, Vriska had Tavros take her to her quest bed. She then relinquished control of him and told him to kill her so she could become a god and end her suffering. Tavros couldn't do it, which made Vriska loathe him. She did, however, die naturally and become a god.
[She got her eye back and everything!]
Her status as a god gave her the power to steal luck from anyone around her, making her the luckiest person to ever exist, and incapable of losing games of chance.
In the final battle against the Black King, Vriska delivered the final blow that took him out.
On the meteor, Vriska took an interest in John, and realized they had a lot in common. She decided she would mold John into the ultimate hero of his game, and John agreed. She then went on to manipulate the kid's game, so all the bad things that happened would be her doing, planting herself in the history of the session forever. She did this so she could be the one to create the god-powered Jack, and be the one to defeat him, being the greatest hero of all time.
He also got her to gain a celebrity crush on Nic Cage. Somehow.
[Wow Vriska obsessed much?]
When Tavros found out what she did, he decided to take her on and stop her from wreaking more havoc. She took his challenge, and even said she'd let him have the first strike. His readiness to take her out, after wimping out of EVERYTHING up to that point, pissed her off so much that she killed him almost instantly.
Vriska would soon regret this, and after helping John become a god she spoke with him and told him every bad thing she had ever done. She went on to say that, from a troll's perspective, everything she had done was acceptable, but she still felt remorse, and was scared that she felt it. John told her the things she did were bad, but he was still very understanding and helped her cope with it. It was around this point that Vriska fell in love with him. She told him she was going to go fight Jack, but she'd message him again before she did.
During this time, she was caught in the middle of a showdown with Eridan and Gamzee.
This was cut short by Kanaya, who also punched Vriska in the face.
Vriska thought this was insanely hot and was obviously turned on by it.
Anyway, Vriska kept true to her word and messaged John one more time. She told him she was about to fight Jack, then asked him out on a date when they would finally meet in person. Terezi came in, and a showdown between the two happened.
It was decided by the toss of a coin, which of course Vriska won. Had she gone on to fight Jack, she may have stood a chance. This would, however, cost her the life of all her friends.
Terezi could not let that happen, and killed Vriska as she was leaving.
The death was considered just, and she stayed dead. Then John agreed to date her.
They would date, though, in the afterlife. Vriska found the John that had died early, and they bonded over eternity. They dated for a long stretch of time, but due to the sporadic nature of the afterlife, drifted apart and broke up on good terms.
Then Lord English killed a ton of ghosts, which is apparently something only he can do. One of these ghosts was John's.
Vriska was also stalked in the afterlife by Andrew Hussie, who Lord English had killed in a meta way.
[The people who take this seriously deserve to be shot]
Vriska encountered Tavros again in the new universe, when they were fused together to make Tavrisprite. The abomination couldn't handle existing, and blew itself up.
It did help Tavros and Vriska understand eachother a bit better though, and they teamed up in search of an ultimate treasure to defeat Lord English. They may or may not have started dating. It's hard to get Vriska's take on it.
After talking to the living John, Vriska ran into Meenah, the princess of the original timeline. Meenah wanted to face Lord English head on, and Vriska challenged her over which method they would take to stopping him.
That's the end of Vriska's story. For now anyway.
Her handle is arachnidsGrip [AG], her weapon is 8 8-sided die, and she is the Thief of Light.
