Myostatin (also known as growth differentiation factor 8, abbreviated GDF-8) is a protein that in humans is encoded by the MSTN gene. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family that inhibits muscle differentiation and growth in the process known as myogenesis. Myostatin is produced primarily in skeletal muscle cells, circulates in the blood and acts on muscle tissue, by binding a cell-bound receptor called the activin type II receptor.

Animals lacking myostatin or animals treated with substances that block the activity of myostatin have significantly larger muscles. This could be of economic benefit to the livestock industry. However these animals require special care and feeding which offsets the potential economic advantage.

Mutations in both copies of the human myostatin gene results in individuals that have significantly more muscle mass and hence are considerably stronger than normal. Furthermore, blocking the activity of myostatin may have therapeutic application in treating muscle wasting diseases such as muscular dystrophy. - From Wikipedia

So yeah! Ever seen a Bully Whippet? That kind of super-buffness mutation...in our lions. c: Imagine that! Just a suggestion, though. I don't know if it can occur in actual lions, but meh...nothing I've checked proves or disproves the fact, and who doesn't like drawing buff kitties?

You know... I wouldn't actually mind this xD
And I'm sure others might enjoy steroid lions.

It also occurs in cattle, Belgain Blues being one of the more common examples, as well as Piedmontese. (I've seen a Brahman calf with it as well, but I'm getting off-topic x3)

If it had some actual impact on the breeding of the lion / lioness, that could be really interesting...
'Double-muscled' cattle such asBelgian Blues have a lower fat % in their body due to converting protein into lean muscle more easily, so a lion with it would possible require a higher food intake?
As well as the increased amount of muscling causes issue with reproduction. The semen quality, quantity and testicular weight (sorry folks x3) are observed to be reduced, and females have a more difficult time giving birth, due to a narrowed birth canal and the young being bulkier (because of the muscling)
So I would expect maybe studs to have a decreased litter size on average (/ occasionally just shooting blanks with the breeding, even if it was a goddess fertility lioness) And a lioness with the mutation would only have 1-2 cubs, unless a fertility item was used, due to having more difficult births. Would not affect her fertility though.

But, conversely, it could also lead to an increased rate of stat gain (if you wanted the genetic condition that causes protein to be converted to muscling to behave in a realistic manner), possibly a 1-10% chance of an extra stat while hunting or patrolling.

Or, it could be introduced as a purely cosmetic mutation like the others, but I do think that would be a mutation with a lot of potential for affecting the gameplay x3

Anyways.
Cool idea x3

I support this, and I'd also support it affecting game play since we have mutations that do that already (although they are right now only negative mutations). Something that has both positive and negative benefits would be fun!

I figured it would affect stat gain, esp. Strength and Speed, but I didn't remember about the fertility because muts are already ridiculously...not so xD. Actually, as it stands, it would be as much work for the mods as the first lethal mutation - new linearts, a possible modification to the way the lion's stats work, litter size adjustments...oh, my. It'd be a lot of coding. x'3 If they're up for it, they'll be up for it, right? c: And if the whole multi-mut thing is introduced, then maybe the multi-limb mutation could become sort of nonlethal, with the offset of the myostatin-less spider lion requiring a lot of feeding? I've thought about it a lot. But my programming skills are crud, and I don't know if the admins can pull it off. :3

Idk either Akatariel x3

Like, I had to go find the quote, but this -

That's a lot of work with just changing the EARS x.x"
I mean, they likely had to change it for every base, mane type & colour, every marking (in every colour)... Yeah x.x

Lots of work to make a whole new lineart for a new mutation x.x
Most of the current mutations are either just overlays of the normal lineart (claws, teeth, achromia) or a slight alteration of it (fuzzy, fluffy, shaggy)

Mind you, I really do love the artwork for the lethal mutations, it's a big improvement over the older linearts o.o

I do want multi-mutations, but they'd have to be rare to the point of improbability. Even just getting two of the common ones floppy ears and achromia to cross over would be a really feat x3
