Error 721

Error_721 (nicknamed "721") is a creepypasta commonly said to be "the New Null". According to the pasta, a former Zplay employee was fired by hola (the creator of blockman go). Now he wants revenge on Zplay and Blockman Go players alike. Entity 303 is said to be not just the former employee but a whole team of hackers going by usernames like "NullsWeek721," and "entity721unkown". (they join your game and spams in chat atuff like "become one of 721 hackers or else we will hack you")If you have any files in your computer that are named anything with "721", then it could be 721's hackers. 721 can also hack in to player's servers and corrupt them. 1/40 players are affected by 721 and his team.

The following is an email from TheSunny12GM, the first person to encounter Error 721. that was suppose to go to Speed, the first person to ever speak out about 721 TheSunny12Gemail has since been deleted.

Hi, Speed. My name is TheSunny12GM. I'm a huge fan of Blockman Go, and I've been playing for about two years now. Every day after school, me and my friend, John would always play on his hero tycoon 2 server. He was a bit of a noob at Blockman Go, but since he was pretty rich, he decided to buy a party so we could play multiplayer skyblock, along with my friends, Vincent and Brady.

One day, we all were in a group Skype chat and we were working on a huge survival city that we were in the process of building for at least 8 months. We were really proud with how it turned out. It was located in a desert, so we appropriately named our city “Drybones.” All of a sudden, while we all went to grab supplies to finish the hotel that we were working on, John noticed something strange in the chat. The only plugins that we had on the server were Essentials, along with some plugin that Brady found called “SocialSpy.” Thanks to SocialSpy, it seems that someone named “player.number:721” used the command “/stop.” Now, John suffers from major anxiety. I’ve known him since preschool, and he’s always been a really insecure person, so when he saw that a so-called “nonexistent player” tried to shut down the server, he immediately thought that it was a hacker. At first, I thought it was just a bug or something and that he was being paranoid, but I reminded myself that this was a private server. I set up the plugins for him and such, and I kept his server whitelisted, since he didn’t know how. There was no way anyone could join except us.

i checked the server control panel, and it showed we were the only ones on the server. I was getting a bit confused. We all decided to just ignore it and continue on with our survival. It’s about 20 minutes in, and I’m walking with Vincent to the nearest forest to grab wood, which wasn’t very near at all. All of a sudden, we see a noob avatar in the distance of the desert. It appeared to be in the model of some type of model for a macorony hair, with what I could barely make out as red eyes and a wide open mouth, I quickly took a screenshot and ran after it.

For some reason, Vincent’s player just stood still. I assume it’s just lag, but he’s not even speaking on the skype call. I check skype and ask if he’s still online. No answer. He’s not even on the Skype call. By now, Brady is just ignoring us and concentrating on the hotel, and John is freaking out. I can hear the shakiness of his voice. Anyhow, I open up Minecraft again to see that the white figure disappeared, and Vincent disconnected from the server. I try calling him on my phone, but no answer. It goes straight to voice mail. I try texting him, but the texts don’t deliver. John’s getting worried, to the point where it sounds like he’s about to cry. Brady isn’t even listening to us, he’s not aware of the situation at all. I finally get his attention, and he finally realizes how peculiar this problem is. He runs to me and helps me search for the noob like figure. Now, John’s hysterically crying, thinking that the hacker killed Vincent IRL or something.

Suddenly, my screen starts glitching. It’s not normal for Blockman Go to bug out like that. It looked like it was corrupted or something. If that’s not bad enough, the chat starts spamming “Object successfully summoned” by “player.number:721.” I look at the skype chat, and realize that someone has joined the call. It does not have a username, nor did we get any notification of someone getting added to the call. John’s just watching this all happen. His voice is shaking, and I can hear him sniffling. Honestly, I was starting to get a little freaked out myself. Brady seemed to leave the call and disconnect from the server, possibly out of boredom. I’m trying to calm John down, but he simply repeats “I CAN’T TAKE THIS. THIS IS TOO MUCH FOR ME.”

The anonymous skype caller finally puts facecam on. It’s too dark to see anything. John gets too overwhelmed and leaves the call and server. I don’t blame him, if he stayed any longer, he’d probably have a mental breakdown. It’s just me and this anonymous player. I ask if there’s anyone there. I hear a faint voice saying something like “MAKE A WISH.” It was faint, yet it sounded like a voice changer. I decide to switch on Blockman go to see if the player is there. The chat spams with “FILE OVERLOAD” in red text, along with “MAKE A WISH” in gray text. I suddenly get poisoned with a potion of blindness. I then lose my ability to move. I can’t even turn off my computer or exit out of Blockman Go. This player then runs up to me. It seemed to have a noob avatar on, with red eyes and a large open mouth. The chat then says one more thing. “Make a wish, and say goodbye to your friends.” The skype call drops and somehow exits out by itself, and the player runs up to me and hits me. For some reason, it makes that ”https://m.youtube.com/watch?v=jmoCyy2ruzc" noise that used to exist in Beta and earlier. My computer then shuts off. I try to turn it on, but to no avail. I try using my phone, but the internet is down.

I wait about three hours before turning on my computer. The desktop wallpaper was changed to green coding, probably hex. I then realize that literally everything except the Recycling Bin was deleted from my PC. I turn off my computer and use my laptop. I try calling John, but he doesn’t answer. The same goes with Brady and Vincent. I decide to just go to bed and go to school the next day to speak with John and the others the next day. I go to school the next morning, and Brady is the only one to show up. He says that Vin and John’s parents called his parents and ask if John or Vin are at his house. Apparently, they went missing. There was no sign of them, and the police came to their houses and check to see if they were any clues on where they were, but there were no results. I decide to ditch school and walk to John’s house to see if he’s there. I see his mother sitting on the steps, crying. I ask if she’s ok, and she says that John apparently……got kidnapped by a man in a mask. most likely snuck out to the park or something, the traffic cameras caught him getting grabbed. She handed me a piece of paper that she claimed to have been left on John’s computer table. I read the note carefully. “I can’t take this anymore. I can’t sleep, I’m afraid he’s watching me. I can’t live like this knowing that someone is after me, i need to sneak out and run from this hacker and murderer. I’m sorry mom……I love you.” I started to cry a bit when I read those last few words. I check the back of the paper, and written on the corner in very small text was that familiar phrase……”MAKE A WISH.”After about 20 minutes of comforting John’s mother, I leave to go check on Vincent. His dad’s car is in the driveway, but no one is home. Not even his dad. I sneak in the house, and what do I see in the bathroom? Written on the foggy glass of the mirror said "Make a wish" That was when I realized that these weren’t just coincidences. This was a serious issue. Not just some hacker, but someone who is hacking ip's and making victoms “disappear.”

If you get this email, Speed, and if you ever encounter “721” again, I want you to quickly close out of your Blockman Go and shut down your computer. I don’t want you to end up like Vincent or John. Please be careful……if I get more information, I’ll contact you immediately. Good luck!

2nd encounter (Mattsun)

12/13/13

I was playing with some friends on Playstation 3, playing Blockman Go and we were in Realm City building a big house. The house was actually turning out pretty well. We were all having a good time until ThatKidGamer's house started burning.

Now, of course, we had all heard of trollers, but in fact we were blaming everyone. In fact, another house started burning as well. We blamed the host using his host privileges. However, we were WRONG.

We all decided to investigate what was really going on. We all went to a house together, (including the host) only to see the most scariest thing happen.

We looked through the windows to see Blocks being placed by themselves somewhere in the distance. We were all starting to get scared, and would get even more scared.

We then began to look around houses in realm city, most of them were on fire. There was nothing that could set these houses on fire, and fire spreads was off, so was TNT. I tried to believe the host was trolling us but that was starting to get hard to belive

Once more, crap started happening when we were all together, including the host. No one was missing in the house. I counted our avatars, and we were all together. But stuff was happening and we couldn't explain it.

To my surprise, we started finding signs and TNT going off. It was too much. I plugged a cable into my Xbox and into my computer. I opened up a program used to read the source codes that were going on. To my surprise, the source codes described this entity as "721".

My source codes soon started getting out of control. Weird "721" entity codes were showing up and I couldn't stop them. My computer was being overwhelmed with this! I tried to find out who was causing this, but I just couldn't. Just 721 did this and that, nothing else. Nothing.

But not everything was caused by him. The host started trolling us to scare us as well. it wouldn't be a secret for long. The source codes told me everything that was happening INCLUDING what the players did, and me as well. But then the source codes were done. They were surely DONE for it.

No matter how hard I tried, I couldn't figure out what was happening. But the source codes soon spelled out the words "Make a Wish". I thought this was the host, but then started blaming everyone again. As you can see in the source codes I highlighted everything that the error 721 did. Block 1241 is TNT. Item 3213 is Flint and Steel. Block 4 is wood. And also in the RAR of the world, I highlighted "MAKEAWISH" as I said earlier. This list went on and on, completely busting my computer. But one question remains: Is This Null?

Soon, the host had to go to sleep and left the world. However, the source codes were still working, no idea why, and the world was off. Error 721 was still controlling the world. I decided to exit my program and see if anyone had seen this mysterious "Error Code" on the Minecraft Forums. There were a few people. Some of them sent me pictures that they have taken, and only one Mobile player took a picture as he had seen it as well. He said he was playing with his friend on a private Build At Sea server. As you can see, they encountered it as well. Yes, it has a texture pack but he sent me the pack and there's no mob or block with White eyes, looks like a weird noob, or has a creepy mouth.

Soon a mysterious profile on the forums started to chat with me. He only said a few words and then left the chat. "Hola will think you are crazy when he sees this, by the way. YOUR NEXT". i hurried and clicked on his profile. But the page 404'd. Soon I recieved an inbox message from him and clicked reply. I asked him where Null was only to get back a scary reply.

I got this message: "I replaced him. He has died. He is no longer with us, nor anyone else". I was using another website to reply to him for protection. On the forums, my account suddenly signed out. I tried to sign back in, only for the forums to tell me "Your account has been deleted for the following reason: Stop". I couldn't believe it! thats just like the white entity story!( https://blockmangocreepypasta.fandom.com/wiki/White_entity ) I made another account and stopped researching and went to sleep as well.

I HAVENT SEEN THE STRANGE ERROR CODE AND CREEPY PLAYER SINCE

Conclusion

There have been many more sightings after this one. The first person who saw 721 has disappeared from the internet. He hasn't been heard from since December 10, 2015. The most recent encounter (as of 7/7/2020) is when on July 7, 2020, the second encounter person (Youtube: NonameBG) was Skype texting with a friend. In the middle of the conversation, 721's team hacked his computer.

If you see things in your Blockman Go games like Birch wood in oak trees, fire in the sky, random cobblestone where it is not supposed to be, upside-down crosses, weird/creepy noobs in the distance, or other suspicious occurences, error 721 could be hacking your Blockman Go. If you think you've been hacked, look through your whole computer and delete files with "721" in them. Remember, a lot more than 1/40 people are affected by 721. There are some people pretending to be Error 721. If you see someone on Minecraft with the username "Error_721" then just ignore the person. Be careful and stay safe.

If you see anything weird in your worlds, post a comment showing the picture.

UPDATE (January 5th 2021)

He said that we have 5 weeks to train because the war will be in 5 weeks. Get ready guys. He also said to look out of your window at night because he said that he is going to take more children. Children are disappearing and the last thing they did was Blockman Go. Also, NoNameBG's team discovered the "Sulfur of Immunity". It is an IP address that protects you from 721. It is currently unknown how it works. If you haven't been affected by 721 yet, it will happen in 5 weeks.

TEAMS

Error 721 cannot be beaten just by fighting alone. So, some people created teams. The team leaders recruit members over the internet to fight Error 721. Nonamebg's team is the first one. Name's team has a special server called the "Sulfur of Immunity". A thing that protects you from 721.

stay safe everyone
