As any player can see by perusing the Lion Wardrobe, Lioden is absolutely chock-full of mutations. Here, we're focusing on a type of very rare mutation: Lethal! Below, we have included all information regarding the saddest mutation type on Lioden.
Introduction
Mutations were introduced to the site on April 12th 2014 within this news post. What mutations were added in during that update are not detailed, however the very first mutated lion was hinted at two days later in this news post.
It is mentioned within the first news post that "the more severe the mutation, the more chance it may prove fatal for the cub or affect gameplay in some way". Lethal mutations, as the name suggests, are mutations that will impact your lion's life to the point that they die at an early age. These mutations are incredibly rare, and the majority of them will kill a lion before they reach adolescence. These mutations are all visible from birth as well, so you'll instantly know if something's wrong with your little cub. Let's see what some of these mutations are!
Lethal Cub Mutations
The following lethal mutations are ones that only affect cubs.
Cleft Palate
Cleft Palate is a lethal mutation where your cub has a split in their lip and roof of their mouth, causing them to have trouble with nursing.
Cleft Palate cubs will pass away on the rollover that they turn 3 months old.

| 0 Months | Your lioness gave birth to Cub, a slightly deformed baby. She's unsure if it will survive but it seems to crawl for milk like all others. |
| 1 Month | Cub crawls around using its front legs only. The merged hind legs don't seem to bother it, and it seems to be able to poop just fine. |
| 2 Months | Other cubs this age prance around, but Cub just paws at nearby insects, making it a bit of an outcast. |
| 3 Months | Cub's mom is worried for it - it does not seem to grow much lately. |

| 3 Months | Cub died last night due to lethally deformed head. |
Lethal Adult Mutations
The following lethal mutations are ones that can affect a lion from the newborn stage to adult stage.
Deaf
Deaf is a lethal mutation where your lion lacks the power of hearing. It is also the only lethal mutation that does not change the way a lion looks; however, it does change many mechanisms connected to lions. Deaf lions cannot hunt, patrol, or be a king. If a deaf lioness is pregnant, she can die while pregnant; a deaf nursing lioness, however, cannot die while nursing.
What's also unique about Deaf lions is that they give updates about your lion's health, as well as unique flavour texts specific to the Deaf mutation!
Deaf lions can die randomly between 4 months to 4 years of age. If they live to be 4 years old, they will pass away upon the next rollover.

If your lioness gives birth to a cub with the Deaf mutation, you'll receive the following birth message.
| Deaf Birth Message |
|---|
| Although there is nothing visibly different about Cub, it isn't long before your lioness notices that they do not respond to calls like the other cubs. |
As your Deaf lion ages, you will receive occasional updates about their life with a lethal mutation. These messages will only occur if your Deaf lion is 3 years or older.
| Deaf Health Messages |
|---|
| Had it not been for the vibrations from the stampede, [NAME] would have been promptly trampled by the oncoming mass of wildebeest. |
| A stalking poacher would have put a quick end to [NAME], were it not for the hunter's poor ability to aim. |
| An approaching pack of hyenas nearly made a meal out of [NAME]. Fortunately, another lion scattered them off before [NAME] even realised they were there. |
| You notice [NAME] delicately sniffing at flowers that are surrounding your den. They've decided to stick close to home today, unwilling to get in the way of any pride members. When they notice you're watching, they smile and greet you with an odd-sounding meow. |
| Perhaps [NAME] being deaf isn't such a bad thing. While exploring, a colourful bird decided to appoint itself as your new best friend, and has taken to cawing and tweeting every few seconds.. Very, very loudly. You're envious that [NAME] is completely oblivious to the obnoxious feathery idiot. |
If you visit your Deaf lion's page, you may receive some unique flavour texts that are specific to the Deaf mutation.
| Deaf Lion Interactions |
|---|
| [NAME] may not be able to hear you approach, but he/she always seems to know when you're near. When you question him/her about it, you were told your smell gave you away! Maybe it's time for a trip to the waterhole? |
| You tried to tell [NAME] a funny story about something that happened when you were exploring, but he/she didn't appear amused. Seems like your story fell upon deaf ears. |
| You were startled awake by [NAME] rearranging some rocks within your den. It seems he/she hadn't realised how loud he/she was being! |
| [NAME] seemed upset that she couldn't go hunting with the others. You began to explain that it was only to protect her from any threatening predators, but stopped when you realised it was a futile effort. Instead, you chose to sit close to her and nuzzle her comfortingly. |
Sadly, once it's your Deaf lion's time, you will receive one of the following messages upon their passing.
| Deaf Death Messages |
|---|
| [NAME] was found dead on the outskirts of your pride's territory. They appear to have been lethally shot by wandering humans. Of course, they couldn't hear them approaching. |
| Your pride members found [NAME] horribly mutilated out near one of your hunting spots. Judging by the wounds, they were viciously killed by a vengeful elephant. |
| Today, your pride is mourning the death of [NAME]. They were scavenging near the river, and didn't see the nearby crocodiles. One of your pride members called out a warning, but [NAME] was unable to react in time. |
| [NAME] was caught unaware by a stalking leopard, who quickly dispatched them. |
| If only [NAME] had been able to hear the rattle, warning them off from the snake's nest. Alas, the warning went unheeded, and the mother rattlesnake struck swiftly. |
Helpful Items
If you're looking to breed for a lethal mutation, or your perfect breeding project cub was born with a lethal mutation, these items may be of some assistance to you.
Before Breeding
It's ideal to give these items to your chosen lioness before breeding her, as using a GMO Cow, Lion Meat, or Lion Scrotum on an already-pregnant lioness will not affect the litter she's currently carrying. She must be given these items before her breeding takes place in order for them to affect her next immediate litter.
In regards to Cotton Root Barks, it's advised to use them on a dud breeding, then breed her to your preferred stud once she's back in heat after miscarrying.

Removing A Mutation
As mentioned previously, although it is incredibly rare, there is a chance you'll breed a gorgeous cub that happens to have a lethal mutation. If you wish to remove its mutation, you can use the following item.
Preserving A Mutation
As lethally-mutated lions die much earlier than healthy lions, you may be worried about losing your beloved mutated cub (or lion). To preserve your lion in their current state, these items will help you.
Frequently Asked Questions
Q: Can I remove a mutation from my lion?
A: Yes. If a lion is born and you do not wish for it to have a mutation, or you want to save a lethally-mutated lion before it passes away, you must use a Safou Fruit. They can be bought for 1000 SB from Monkey Business.
Q: I had a lethal mutation born! How can I prevent it from dying?
A: You can either use a Safou Fruit to remove its mutation, or give your cub a Jellyfish. Jellyfish are given out as a rare jackpot prize from the Slot Machine game on Lioden. Note that if you wish to use a Jellyfish to preserve your lethal cub, you will need to have available frozen slots.
If you're wanting to freeze an adolescent or adult lethal lion, you will need a Turritopsis Jellyfish, which can be bought for 5 GB from the Oasis. You will need an available frozen slot in order to use a Turritopsis Jellyfish as well.
Q: What happens if a lethal cub dies?
A: When a lethal cub dies, the owner has 7 days to store the cub into their Pride Dynasty before the cub's records are permanently deleted. The owner can choose to keep their lethal cub memorialised within their Pride Dynasty, destroy their records, or use a Canopic Jellyfish on them in order to bring them back as an immortal pride member.
Q: Is there any way to pass on a lethal mutation?
A: Only for the Deaf mutation. All other lethal mutations are specific to cubs. As cubs cannot breed, they cannot be passed down to offspring. As for the Deaf mutation, you can give an adult Deaf lioness a Lion Scrotum, which will give her a 25% chance per cub to pass down her mutation.
Q: Who was the first lethally-mutated lion on the site?
A: Chernobyl the Extra Limbs cub! They were memorialised within their owner's Pride Dynasty, then brought back as an immortal cub when the Canopic Jellyfish item was released.
Chernobyl was born on April 26th, 2014, 28 years after the actual Chernobyl incident occurred. What strange timing!
Q: Some of the lethal mutation art really upsets me. Is there any way I can request that my account be blocked from breeding certain mutations?
A: No. Accounts cannot be blocked from breeding mutations. Unfortunately, the only way to avoid these images are to block them using external add-ons or programs. If you wish to block an image from your browser, we recommend utilising this guide: https://kb.iu.edu/d/acpv
Q: Are any lethal mutations gender-specific?
A: No. Lethal mutations can occur on both male and female cubs. This means that you can safely sex change a lethally-mutated cub or adolescent without them losing their mutation.
Q: Can my lethally-mutated lion die before its time?
A: Yes. If you do not assign your lethal cub to a broodmother, it can die earlier than its scheduled passing age. Note that assigning a lethal cub to a broodmother only prevents it from deaths attributed to low cub survival rates. It does not stop a Cyclopia cub from dying at 1 month old, or a Deaf cub from randomly dying.
Q: Can my Deaf lion become king?
A: No. Deaf lions cannot hunt, patrol, or be kinged. They can become broodmothers and protect cubs, however.
Q: Can my Deaf lioness die while pregnant?
A: Yes. It is advised to use an Instant Cub Delivery on a pregnant Deaf lioness, as she is at risk of dying even while pregnant.
Q: Can my Deaf lioness die while nursing cubs?
A: No. If a Deaf lioness is nursing, her chance of death is halted until her cubs wean at 5 months of age.
Q: Is there any way to increase my chances of producing a lethal mutation?
A: Yes. Generally, lower fertility lionesses have a naturally higher chance of producing lethal mutations than higher fertility lionesses; however, this natural chance is extremely low. Your best odds would be to breed with your lioness, then give her a Cotton Root Bark to induce a miscarriage. Doing this will increase her general odds of producing a mutated cub, as well as increase the lethality chance of that mutation.
You can use GMO Cows and Lion Meat as well, though they have a higher chance of producing any average mutation, not lethal mutations specifically. It is advised to only use Cotton Root Barks, as they are the cheapest method to producing mutations, but some players have had luck combining Cotton Root Barks and GMO Cows.
