This makes me think about this more, it'd be really interesting if there was some kind of a document or part of the article written about how it was even discovered that acid would debilitate and damage 682, seeing as all the other stuff that have been thrown at him didn't really cause prolonged damage, but o'well.
Still, from what's written in the little termination logs 682 has lost quite a few parts of its body, from its lower jaw to 3 of its limbs; and it recovered. It actually gives some more information about 682 in general though, as to the visual features it can possess (I tried to include as many features as I could, even ones that have already been posted, and I made all the words that describe its physical appearance bold).
SCP-682 is a large, vaguely reptile-like creature of unknown origin.
SCP-682 has always been observed to have extremely high strength, speed, and reflexes, though exact levels vary with its form.
Digestion seems to be aided by a set of filtering gills inside of SCP-682's nostrils, which are able to remove usable matter from any liquid solution, enabling it to constantly regenerate from the acid it is contained in.
and SCP-682 has been seen moving and speaking with its body 87% destroyed or rotted.
Personnel D-085: His throat's messed up man, look at it! He ain't talking- (Gasps and screams)
1400: SCP-682 recovers from exposure, despite the loss of limbs and organs.
at the end of which three of SCP-682's limbs had been severed, its thorax had been crushed, and both its eyeballs had been ruptured. SCP-2599 then seized SCP-682's head, apparently in preparation for pulling it off of SCP-682's body. In response, SCP-682 vocalized the phrase "KILL ME, YOU SACK OF ORGANS, DO IT."
After fifty-five (55) minutes of this process, >95% of SCP-682's epidermis has been abraded away, its anterior left limb has been severed, sixty-three (63) of its teeth have been broken out of its jaw, and its skull has been fractured to the point that both its eyeballs have been dislodged from their sockets. At this point, SCP-682's exposed sub-dermal tissue begins to luminesce. The luminescence rapidly increases until it is brighter than the stadium lights, which eliminates SCP-682's shadow entirely.
SCP-682 becomes entangled with SCP-162, primarily in the lower body, head, and left forelimb.
After four minutes of continued exposure, SCP-682 lunges away from SCP-162, severing its lower jaw and left hind limb, and causing serious tissue damage to many areas of its body. SCP-162 remains attached to the left forelimb of SCP-682.
Forelimb and SCP-162 removed from SCP-682 during re-establishment of containment.
When it has finished consuming all the fluids, SCP-682 collapses on the floor, and begins loudly vocalizing while clawing spasmodically at its face and abdomen
After resuming observation, SCP-682 is shown to be on the floor, with several injuries around its head, neck and legs.
SCP-682 rapidly regenerates damage, and moves to a different wall, developing several sets of eyes on various parts of its body, many covered by thick, clear “caps” of armored carapace.
682 succeeds in extending a long prehensile limb through the hole and maiming two security personnel before containment is reestablished.
SCP-682 examines SCP-524 suspiciously, at which point SCP-524 begins gnawing on SCP-682's anterior right limb.
SCP-507 was physically attached to SCP-682's left forelimb with nylon zip ties while SCP-682 was inactive due to physical destruction incurred during an unrelated containment breach.
High-energy bioluminescent organs on the face, spine, and forelimbs were observed as well on both specimens, usually forming, pulsing, and disappearing again over the course of a few seconds.
At T+84 hours, the laser was used again in an attempt to cut SCP-682-A and -B into more manageable pieces, leading to minor structural damage to the room as the laser beam reflected off their skin.
After ██ sec, SCP-682 grasped SCP-743 with its forelimbs and started pouring the liquid straight from SCP-743 into its mouth.
This just gives a better idea about how 682 can change all the time and how you could literally make up whatever you want about its appearance.SCP-053 approaches SCP-682 and pats its head, causing it to exhale through its forward nostrils.
It's more than likely is what most people would like, but there's going to a second model to this one which will appear after a certain event that happens to 682 in the game, what event I don't know, still didn't figure that out; but it'd have to cause him some severe damage.
Err, I from one point really like the idea of making 682 extra eyes because of 173, and from another point dislike it, because it would imply 682 met 173. Or maybe because 682 is described as really intelligent it would as such figure out that it might encounter 173. But then it's like, doesn't 682's body change according to the situation it's in.
About the size, I don't think you're going to encounter 682 inside the facility, maybe yes, but it's unlikely.
