SCP-527's Addendum

Addendum 527 : 1

SCP-527's bubble gun doesn't originally belong to him. Instead, he bought the gun off of Craigslist. When questioned from who, SCP-527 doesn't remember who he bought it from. Alongside this, the bubble gun has some additionally anomalous abilities aside from the bubbles themselves. The bubble gun does not require any sort of maintenance. It refills and cleans itself with no input from SCP-527. The bubbles produced by the gun are highly durable and cannot be broken by any known methods aside from SCP-1048-E's Area of Effect attack and just letting time pass, as they'll eventually pop on their own. The bubble gun also has a limit on how many bubbles it can fire at once. The limit the gun currently has is 3 regular bubbles and 1 of the special bubbles (bullet, grenade, kinetic, trap) out at the same time. 

Addendum 527 : 2

During my test regarding SCP-527 and SCP-1048-E "Polar," I discovered that Polar's freeze breath went straight through SCP-527's bubble, only affecting the person inside of the bubble. Even after becoming frozen, the bubble didn't pop, and even parts and pieces of the ice cube phased through the bubble but didn't ever pop it. Now, it's known that if you pour bubble soap and stick your finger through a bubble, your finger will phase through the bubble, but SCP-1048-E's ice isn't doused in bubble soap. Also, whenever SCP-527's bubble hits a hard surface, it makes a clinking noise similar to that of metal, which leads me to believe that SCP-527's bubble isn't any ordinary bubble but a special kind of material shaped like a bubble. I also believe that SCP-527's bubble can only be touched by things if the bubble makes direct contact before being touched by anything else, and if anything touches it without it being flown at them, the bubble would phase right through a person. SCP-527 is the only thing that can hit the bubbles, which leads me to my final conclusion of SCP-527's bubble: SCP-527's bubble is a specially made translucent sphere specifically and specially made for SCP-527 that only he can touch and feel.

Addendum 527 : 3

The Bubbles that SCP-527 has produced is unable to be popped by all of Bolts Attacks including its Concentrated Red Lazar Beam, SCP-527s Bubbles were able to withstand everything Bolt threw at it, Showing that there's a special material that the water gun uses not being able to be popped whatsoever it seems like, this material might be the cause of the invincibilty of his bubbles. 

Addendum 527 : 4

SCP-527's trap bubble is able to negate/halt the anomalous effects of the user currently effected by an SCP item/object those trapped by the bubble. This is proven by when I perform a test on SCP-527 with SCP-330 where a CD used SCP-330 Blue and Yellow Stripes candy ( decreases one's size temporarily but later Increases one's mass by twice the size permanently) and when Mr. Fish shoot him with the trap bubble, the CD didn't show any signs of growth nor did it show any effects happening, only until SCP-527 wills the bubble to disappear that the CD was able to grow twice his size.

Addendum 527 : 5

The attacks from SCP-2398 were able to bypass the defense of the trap bubble and harm the CD. This is proven when I was doing a SCP-527 X SCP-2398 cross testing where there were 2 CD's involved with one of them being trapped by the bubble and the other being the holder of SCP-2398, upon the CD with SCP-2398 hit the trapped the CD. The bubble didn't burst nor show any signs of damage instead only damaging the CD inside of it, it may be that SCP-527 trap bubbles are semi-sentient, being able to distinguish attacks that could threaten it's destruction or not, meaning that the trap bubble, knowing that it can't tank SCP-2398's hit passed it to the CD trapped inside it, using the CD to also protect itself.
