Addendum 127 : 1
SCP 127 can effectively be "adopted" by a individual after interacting and befriending SCP 127 for a long enough period of time. This bonding system requires both the usage of SCP 127's favorite pastime (dancing) as well as a conversation between the user and SCP 127. After this, SCP 127 will exhibit "dog-like" traits such as loyalty, protectiveness, and extreme interest towards the user; normally, Gunther does not allow random people to pick him up even if he is lying down on a table and even then fire him, but after this bonding technique Gunther will allow the user to fire his gun, which is extremely powerful. In his full form, Gunther will also protect the user from verbal/physical attacks, again referring to the protective nature of SCP 127. SCP 127 will show extreme signs of sadness and loneliness upon learning that his bonded friend will be leaving, going as far as to show affection by using his omidirectional gun to "kiss" the user.

SCP-127, also known as "Gunther" or, "The Living Gun", has been observed to show deep resentment and distrust with SCP-035. SCP-127 will maintain distance from anyone wearing SCP-035 and show clear signs of distrust.
SCP-127 has also been observed attempting the neutralization/termination of SCP-035, after witnessing a individual it has spoken to briefly perish from 035's effects.
This also implies that, how SCP-127 feels about someone affected by 035 also seems to entirely depend on whether 127 has seen the individual before they placed the mask on.
For example, an individual who put SCP-035 on before letting 127 see their face, is far less trusted.
Whilst an individual who has come into contact with 127 prior to putting the mask on will be trusted perfectly, and will be deeply missed.

SCP-127 recognizes it is different from typical firearms. Although it doesn’t consider itself an expert, it has a working knowledge of how each part of a firearm functions, how reloading operates, and is aware of various firearm types. SCP-127 also understands the functionality of attachments like sights and silencers and is familiar with different ammunition types. However, it lacks knowledge about firearm maintenance, the appropriate use of firearms and ammunition in specific combat scenarios, as well as distinctions between long and short-range, and non-lethal weapons. It does not fully understand safe firearm handling but acknowledges the potential dangers firearms pose to users. Despite these gaps, SCP-127 is eager to expand its understanding of firearms.

SCP-127 is a highly intelligent sentient being that possess cognitive functions such as the ability to retain memories and recall information from memories to assist in identifying hostile/bonded individuals.
Addendum 127 : 5
In different scenarios, where a bonded individual's life is at 'risk' of danger, depending on the risk posed, SCP-127 reacts differently in each scenario. Overall, SCP-127's protective nature and willingness to use force to protect individual's seemingly differs when an individual's life is in an immediate danger, SCP-127 will neutralize the 'attacker' whilst if an individual repeatedly verbally assaults an bonded individual, SCP-127 will ignore them until the bonded individual express's distress, which is when SCP-127 becomes it's gun state to allow the bonded individual to take 'revenge' upon the other individual whom verbally insulted them.
