Red Lizard

Red lizards are the largest species of lizards in the game. They have a myriad of spikes on their black backs and tend to have a very distinct red coloration in their spikes and head. The head will fade from black to red and back sometimes.

They cannot be "natively" found in any region as their spawn chance is always at 0% by default in the code. Only through mostly unknown methods can they spawn, however, once they are met a red lizard may spawn in one of the region's lineages. These lizards can spawn in any region of the game where other lizards are present.

Spitting
The red lizard is the only lizard in the game that spits projectiles, slowing you down and making prey easier to kill. The spit itself is not damaging but it briefly stuns you and makes you immobile. It can knock you off of poles quite easily, and can even cause you to drop your held items. Since it has the highest visual range in the game out of all the lizards, it is more likely to spot you before you see it and come charging.

Movement
Red lizards can climb poles and cover ground very quickly. The projectiles will slow down its target, letting it catch up to prey even faster.

Senses
Like most lizards, the red lizard can see and hear when something is close. However, the red's auditory and sight senses far outrange other lizards, making it nearly impossible to sneak by.

Bites
The red lizard is the most dangerous lizard in the game, with a 100% kill chance. Slugcat has one health. The Red Lizard deals much more.

Combat
Red is the most difficult lizard to fight due to its tenacity, speed, and spit, but it can be defeated. Having scavenger bombs and spears help, as this lizard's toughness lets it stay on its feet even when hit in the head. Also this lizard tends to fight quick and dirty, you cannot outrun it, and if you try it will spit at you to stun you before swooping in for the kill bite.

The best way to fight it is to trick it with tunnels, briefly when exiting a tunnel with a red, shove a spear into it, and tunnel back. Wait for it to follow before tunneling back out, then back in, grabbing the spear and spearing it again. This will work in very tight corner tunnels, but it also has a possibility of having the spear miss if you're not close enough to it. Since the red lizard is very tough, you need a good deal of spear hits. A minimum of 10 has been consistent so far. If the lizard gets too injured it will try to run, but unlike most other lizards, it will snap at you if you get close. Be aware that though it is rare, this lizard can still perform the charge attack typical of green lizards. It is extremely fast but can be jumped over with some difficulty. This is the only lizard with a 100% bite kill chance, so one bite and it is over.

Stealth
Sneaking past this lizard is extremely difficult. If you are to attempt it, stay far out of its line of sight and crawl along the ground. Even sneaking perfectly may not suffice though, as it has the highest hearing range and visual range of all lizards and homes in on you relentlessly.

Evasion
As stated before, this lizard is fast and can easily keep up with you. If it cannot it will spit at you until you are too stunned to stop it. Climbing on poles must be done quickly as the lizard will always attempt to spit you down. One way to get away from it is to seek high ground. Red lizards can only climb poles, so if you get to an area they cannot climb or teleport to they will be unable to kill you. If caught on the ground and forced to flee without any tunnels to escape through, you can outrun it and dodge some of its spitting attacks by sliding along the ground, followed by the instant pounce this allows. Doing this consistently should allow you to survive an encounter. Alternatively red lizards may be distracted by other creatures like squidcadas and scavengers, which they will regularly hunt or may be hunted by other critters like pole mimics or vultures, which provides a handy distraction for an escaping slugcat.

Taming
It can be done, although it is tedious and dangerous and you must know for sure where the lizard will spawn. It has been tamed with scavengers and squidcadas, with the average amount needed to make it not attack you on sight be around 5 and the average amount needed to make it follow you and sleep in your shelter with you around 8.

Trivia

 * Red lizards have the highest stats in Bite damage, Bite percentage, swimming speed, and visual range.
 * to make a red lizard appear you have to kill lizards in one region repeatedly until one respawns as a red lizard. This is caused by the Lineage System
 * Its been postulated that having one red spawn might also increase the chance for more reds to spawn, but his has not verified.
 * Red lizards will fight one another if they get too close.
