Red Lizard

Red Lizards are the the largest, most aggressive, and deadliest species of that can be encountered in-game. They do not spawn natively on or  and can only be encountered through the lineage system in these campaigns.

Red Lizards have a 100% or 1/1 bite lethality rate.

Appearance
Red Lizards are some of the most decorated Lizards, typically featuring long, thin frilled tails and backs adorned with spines. Some may exhibit smaller and darker back spikes. They are usually bright red, but may occasionally be more orange, and rarely light pink, peach and salmon colored. Red Lizards have the longest average tail-to-body ratio of any Lizard, and may feature up to four distinct scale types on a given individual.

Combat
Red Lizards are by far the most difficult and dangerous Lizard to fight due to their extreme aggression, speed, ability to disarm with their projectile spit, and resistance to injury - they can take 6-12 before dying. Additionally, hitting them with does not flip them over like other Lizard breeds, and they are very resistant to explosives. Hitting Red Lizards with a Spear to the mouth with techniques such as crouch- or slide-spearing stuns them for a longer than average period, granting the opportunity to get some free hits in at their body, and explosives may also be used to stun them for a moment. A tamed can be a valuable ally to have when fighting Red Lizards due to their immunity to Red Lizard bites.

Stealth
Sneaking past Red Lizards is next to impossible due to their heightened senses of vision and hearing; they can hear and see prey from far off-screen and do everything in their power to make their way towards their quarry. Additionally, they are typically found in long, flat stretches of terrain, giving few options for sneaking around them.

Evasion
Due to their speed, evading Red Lizards can be quite difficult - they can catch up in the blink of an eye. If a Red Lizard is in the way, always retreat to a location where it's easier to maneuver around them. Getting to sheltered high ground is recommended due to Red Lizards being reliant on poles and creature tunnels, but must be done quickly as Red Lizards may utilize their projectile spit to knock prey off poles and high ground. If running away from a Red Lizard, it is possible to utilize the knockback from their projectile spit to boost towards an exit. Additionally, finding a group of other creatures such as, , or even other Red Lizards may distract them, buying time to get away safely. Advanced movement, such as slides, also helps in outpacing them.

Projectile Spit
Red Lizards, like s, have the ability to spit projectiles at their prey. Whilst the spit itself does not deal damage, it causes a large amount of knockback, weighs down whatever it is attached to, and can even disarm the player. The projectiles have an impressive range, but Red Lizards must stop moving to shoot them. They shoot these projectiles at about 4 times per second.

Fearlessness
Red Lizards are not afraid of or, and subsequently are not affected by their respective. They do however still fear Red Centipedes, even when tamed.

Tongue
Rain World Remix - Only occurs when the "Alpha Reds" option is enabled.

When chasing prey or fighting against other Lizards, Red Lizards use their tongues. Unlike other base-game Lizards' tongues, the Red Lizard's tongue is incapable of pulling the player in. Instead, they steal an item from the player's hand. If this item is a Spear of any sort, the Red Lizard bites it in half, destroying it. This theft can potentially harm the Red Lizard - for example, if they steal a Spear that is Explosive.

Taming
Red Lizards are the most difficult and time-consuming Lizard to tame, typically requiring 7-9 feedings. Care must be taken when feeding due to their speed and aggressiveness. They are capable of fending off the vast majority of threats, and keep fighting until killed, but cannot climb on backgrounds and so have difficulty pathing through some rooms and consequently between regions. Mostly-tamed Red Lizards follow the player relentlessly and can still bite and kill Slugcat, which is an issue in Shelters. Biting can also happen accidentally with fully tamed Lizards.

When playing as Monk or Survivor they must also first be lineaged. Red Lizard lineage dens can be viewed on the interactive map.

Trivia

 * Unlike most other creatures only found natively as Hunter, Red Lizards were present in the game before the 1.5 update, but could only be encountered via the lineage system.
 * Red Lizards have the highest visual range, swimming speed, and vision when looking into water from the surface of any Lizard.
 * This technically makes them better at swimming and looking into water than, who have 0.2 speed and 50% vision compared to Red Lizards' 1.9 speed and 95% vision. However, Red Lizards cannot dive.
 * They move so quickly in water that the water around them is displaced.
 * Red Lizards attack others of their kind on sight with an extreme aggression not exhibited by any other breed, almost always resulting in a fatality. They are mostly neutral towards other Lizard breeds.
 * Red Lizards are capable of killing Red Centipedes, but they usually don't retaliate because of their fear towards them. They lose this fear when tamed, and attempt to kill any Red Centipedes that threaten the player.
 * Unlike any other Lizards, Red Lizards attack - and often kill - King Vultures (and even, though this interaction does not often occur naturally). Additionally, and , who usually attack all other Lizard types, attempt to flee from Red Lizards.
 * Even if a Red Lizard is holding a creature in their mouth, they can still fire projectiles.
 * Red Lizards are capable of biting every frame.
 * There is a 1/10,000,000 (one in ten million) chance that a Red Lizard's bite may fail.
