Chameleos' body is covered by a purple and white hide on its body, the Chameleos' head is also large, flat, and has a spiked "crest" with a horn at the tip of the head, which can be broken for extra reward. Its eyes are similar to a chameleon's eyes; large and orb like with the ability to freely move seperately from each other. Its tongue can be stretched, making it very long and able to steal items from Hunters. Its wings are purple colored with a greyish white membrane, the wings are only used when moving to another area and during its poison jump attack. Chameleos tail is large and shaped like a leaf, with a curly chameleon like tail at the end.
Chameleos has a special ability to camouflage, making its body completely invisible and sometimes is seen with a fast shine of light, when Chameleos tail is severed and its horn is destroyed, its ability to camouflage becomes disabled. Chameleos can inflict Poison, spitting out acid blobs, which causes your defense to lower and breathing out gas that inflicts Fatigue, which makes you run out of stamina. Its tail is used for making a High wind press (Much like Kushala Daora wind barrier to prevent hunters from getting near it).
Information about Chameleos behavior is very little due to its ability to camouflage, rather than it is like to steal item from hunter with its long tongue.
HC Chameleos has a pinkish tint on its body and different colour spikes. It gains new moves, including a combo move were it launches the Hunter into the air towards it, then spits poison at them in mid-air. In addition strange spurts of greenish-gas appear in the area around Chameleos.

Eyewitness sightings of this Elder Dragon are extremely rare due to its ability to literally vanish; however, details of this are unclear. It is thought that shocking it may make it reappear, but this is unproven.

Chameleos are poisonous and acidic; they can spit an acid blob (which lowers defense), spray acid (drains stamina, causing fatigue) and spray a poisonous cloud whenever they glide.
Chameleos is very sensitive to Fire Element on the chest, front legs and tail. Dragon element is more effective on the wings, whilst everywhere else on the body takes equal damage from both Elements.
Cutting both tail and the horn causes its camouflage effect to stop. Dragon Element is needed to break Chameleos' horn; however, the tail doesn't require Dragon Element to be cut off. Chameleos' total health must be below 30% before the tail can be cut.
Chameleos have sticky tongues, allowing Chameleos to steal items off the hunter.
Throwing a Smoke Bomb on Chameleos will temporarily make it visible.
A much more economical way to locate Chameleos after it's gone invisble is simply to run around in circles and watch how your hunter reacts. Even though Chameleos can't be seen, the hunter will run normally when headed in Chameleos's direction, and panic-run in any other direction.
Felyne Comrades will always know where Chameleos is, even when invisible, so another good plan is to follow their lead.
Flash Bombs thrown in front of Chameleos does not make it visible, but it helps locate its head due to the stars going around its face.
Chameleos can be poisoned, despite the fact it uses poison attacks itself. The poison damages Chameleos and helps to locate its head whilst it remains invisible.
Sonic Bombs detonating near Chameleos while it is in the middle of an attack will make it flinch and turn it completely visible for roughly 1 minute. There is also a chance that Chameleos will drop a Shiny when this happens. This can be done regardless of whether Chameleos is in Rage Mode or not.
When Chameleos is beating its tail on the ground, it will try to steal an item immediately after finishing. This can be evaded by running far enough to the side or behind.
Despite its namesake, its appearance is based off a mix of Uroplatus (leaf-tailed geckos) as much as a chameleon, with traditional fantasy dragon features included as well.
When Chameleos is enraged, music will play in the background. Green toxic gas will appear in its mouth, making it easier to spot while still invisible. However, when it becomes more docile the music will stop playing.
The area Chameleos is in will light up if the hunter has the Autotracker skill, but the Elder Dragon itself will not appear on the map.
Chameleos is a bit off to real-life Chameleons since it can move very fast unlike the Chameleon's slow nature. However, when no danger is present, Chameleos tends to move slowly and cautiously while camouflaged, much like real-life Chameleons.
Chameleos is one of the monsters in the Monster Hunter Universe to have many concepts before the official art released.
Chameleos is one of the 4 "True Elder Dragons", the rest are Kushala Daora, Lunastra, and Teostra, seeing as it, along with the other 3, isn't giant with its own area or is using a giant arena to be fought in.
Chameleos has a new status called "Vocal Cord Paralysis Poison" that causes the hunter to be unable to speak/chat in game along with stamina loss like fatigue.
