Doctor Fentz

Biology

I don't think this woman has ever been to medical school, but hey, at least it's free substances! -Mr SKIM

With a personality of trustworthiness and Kindness, but with intentions that are not so friendly nor safe. Doctor Fentz (Born in January 4th, 1990. At St Mary's hospital) Also by her full name Fentz Janssen Seidel. Is a Supervillain in Romarkia. Widely known for drugging her patients with something known as TM-006. This type of virus can infect the patient in 3 months. Stage 1-3 can be cured but stage 4-6 is incurable. It can cured with frostbite or anyone with ice/frost powers. This is the reason why she doesn't allow her patients to eat anything that is cold (Ice cream, ice, ect). It is unknown if she's a licensed doctor or someone pretending to be one. But it is confirmed that she pretty much knows medical related stuff. She also operates a hospital that is only open from night to 6 am. But Fentz never hired anyone.

She is described as "cold, mysterious, a bit creepy, but still kind no matter what". according to her patients before mysteriously disappearing without a trace. But fentz genuinely cares for her patients. As she does value the wellbeing of both their physical and mental health. She is also widely known for leading a Supervillain group called "Collective Poison And Drugs" (abbreviated to CPAD). Where a group of Robloxians would plan to take over the world using TM-006 and other illegal drugs. The group is known threat in romarkia. And it caused heroes in the country to look out for the members of the group. Some heroes described the group as "Genuinely more threatening than any villain group".

Fentz's ways to cure/heal patients is really bizarre. For example, if a robloxian is having a fever, she would make them have a bath at the hotspring in the hospital while she plays in the piano to calm them down. But the water at the hotspring is contaminated with mecury, fentanyl, and more. Afterwards she would give them herbal tea (which was contaminated with TM-006) before putting them in bed. This is one of the bizzare ways she could to treat a patient. However despite that. She genuinely cares for her patients' feelings. If they don't like the methods she using to cure them, then she'll use a different way that is still bizarre but (un)safe.

Fentz became viral on the news after a superhero (Ember) called her out on Diane's talk show. Where he said that fentz was poisoning her patients and doing inhumane experiments on some of them. Fentz later responded to the claim on Diane's talk show. Fentz said that she did give them something suspicious, but she said she didn't poisoned them. Then she said that she did do experiments, but they aren't that bizarre. Fentz said that what ember is doing is causing damage to her reputation and he needs to cut it out. Because of this, many Robloxians became to go against ember and side with fentz. Since they said that fentz is a trustworthy doctor that wouldn't poison her patients.. in reality she DID poison them and experimented on some of them.

She's also the great great grandchild of doctor hydra. She became fascinated by his unfinished experiments and was desired to finish them. However she dislikes nazis of all kinds. Making her different than her great great grandfather. She did say on the Diane's talk show, that she's very disheartened to be related to someone like doctor hydra. And she also thinks that Neo-Nazis should be subjected to torture Overall, Fentz is regarded by some as not even a doctor

Abilities and stats

Signature weapon

Fentz also uses this to somehow fly by shooting out bullets on the ground and the jumping. Causing her to fly.

Passives and debuffs

Although she was disappointed by being related to a horrible person, she became fascinated by the unfinished experiments. So she decided to drop out of medical school to open her own hospital in secret. Where it would be open through night until 6 AM. She would grab some surgery tools she stole from a nearby hospital. Then she gotten medicine from a few shady Robloxians then she would open her hospital at night. Where she would treat patients with bizarre and sometimes unsafe methods.

2014-2025

Creating Collective Poison and Drugs

On April 27th 2014. Fentz has decided that it's time to create her own group to take over Roblox. So she called it Collective Poison and Drugs (Abbreviated to CPAD). She would Recruit a few members. Then they would have plans about taking over Roblox and other stuff. Fentz has also made the goal of making everyone to give in to TM-006. But sometimes the meetings are quite interesting, for example. All of the members of CPAD (including fentz) decided to work at builder bros pizza. Where allegedly Fox Digital (One of the members) pushed the manager in a oven and cooked him alive.

Another thing that happened was that fentz and her team decided to inflirate a furry yiffcon. Without realizing it's yiffcon. As a result the members screamed and fled because of the unholy stuff they saw. Fentz one said "it's way more traumatizing than anything I saw". This is also explains why fentz hates furry conventions. Because of that incident.

Robloxia High School

On September 30th 2015. Fentz and her team decided to go to Robloxia High School with a container of TM-006. Planning to switch out the water sprinklers to TM-006 to infect students. They decided to use the ventilation system to get to the sprinklers and swap the water out with TM-006. Then one of the members pulled the fire alarm and they fled. Watching as the students and adults get infected by TM-006. This mission was a success.

Jailbreak County

On March 7th 2018. They set out in Jailbreak county. Where They were planning to use bombs which has TM-006 inside. First they went to the prison. Then threw bombs at the prisoners, and the fled. Next they go to the police station, they threw bombs at the cops and fled. They went to many places to throw TM-006 bombs. However was stopped by Shane and officer Roofus coming to end the destruction. As a result fentz and her team fled. This mission was a fail.

Bloxburg

On December 25th 2020, on Christmas. Fentz and her team traveled to bloxburg to cause a bit of chaos. First they began to rob grocery stores mainly to scare others. Then they began threatening innocent citizens with sharp weapons. Brittany immediately confronted them, causing fentz and Brittany having an intense and near-deadly argument. As a result, fentz and her team left. They were unheard and unresponsive for years until in 2025

Comeback

News reported that The CPAD came back. But this time they are in block Chronicles and are more deadlier than ever. They have recently been seen on camera attacking citizens and destroying property. The unity alliance (a superhero group) attempted to try to stop them, however the CPAD always emerge victorious. Because of this, superheroes who were from romarkia are now task to patrol the streets of block Chronicles in Robloxia. However the members are very sneaky. And used disguises to get pass the heroes. And somehow fentz managed to gain trust by some Robloxians after curing them with bizarre methods at her hospital.

Recently on November 8th 2025, the superhero ember went on Diane's talk show to talk about fentz. He said that fentz is Causing trouble for citizens and their safety. He then made the claim she poisoned her patients with TM-006. he has also made the claim that not only is she poisoning her patients but also experimenting on them. Fentz later made a response to ember's claims.

hello everyone.. Dr fentz here.. recently there's this superhero going around and spreading some really wild stuff about me.. so let me clear some things up a bit. First, yes, I did give my patients something suspicious, but that doesn't mean I poisoned them. It could because of humid weather conditions or maybe they ate something weird. Secondly, no, I did not do inhumane experiments on my patients, it's true that some of them went missing after their appointment, but that doesn't mean I am the one responsible for their disappearances. They randomly went missing. Maybe don't accuse me of something like that without proof. Anyways that's all, don't believe anything on tv folks

Because of this response, many Robloxians sides fentz and went against ember. Saying that fentz is a friendly doctor who wouldn't poison her own patients. But in secret, she did poison all of her patients and experimented on some of them. She is also secretly sending fentanyl and drugs to MR skim as a deal.
