Diseased Tail blades:Ex At seventh level anybody who is hit by the tail blades must succeed on a Fortitude save equal to the Dragon's breath weapon save or contract a disease of the player's choice.

Growth:At 8th level the Dragon grows to large size. At 12th he grows to huge and at 19th he grows to gargantuan. His AC, bonus to hit, base damage, grapple and skills change accordingly, but he doesn't get any ability score bonus or penalties.
Stygian Grab:Ex At 9th level the Styx dragon gains the improved grab extraordinary ability. To use this ability a Styx dragon must hit an enemy that is at least one size category smaller than him with his tail blades attack.

Stygian influence: After swimming through the river Styx for centuries the planes they swim through have affected the dragon's attacks. At 12th level The Dragon can now bypass any form of damage reduction that can be bypassed by any evil alignment as if their weapons were attuned to that alignment.
Stygian Corruption: No mind can resist the river Styx. The Stygian dragon can now affect creatures immune to mind affecting with his Mind Affecting SLAs, but those creatures receive a +4 bonus on their saves.
Crush:Frightful Presence:Ex
Bonus feat: At levels 13, 15 and 20 the Styx Dragon gains Extrarodinary disease as a bonus feat (see after this monster entry) or a fighter bonus feat for wich it qualifies for.
Stupefying breath:Su At 14th level the dragon gains an additional breath weapon. The breath is a cone with a radius of 30 feet+5 feet per HD of the dragon and deals 1 intelligence damage for every 4 HD of the dragon. The damage can be halved with an appropriate fortitude save of DC10+Con Mod+Half its HD. The breath weapon recharges in 1d4 rounds.
Disease ascension: At 15th level, the dragon can now bypass immunity to disease derived from class features (Such as the Paladin's divine health) and any ability not derived from a creature's type. However, Styx dragons cannot affect each other with this ability. In addition, the damage die for both Stygian wasting and devil chills increase by one die size.
Corrosion: At 16th level, the Stygian Dragon's natural weapons deal an aditional 1d8 Acid Damage. This Damage increases one die step for every 4 HD gained from here.
Stygian bite: At level 17 the Styx Dragon's bite is a weapon to be feared. The Dragon can now channel its Stupefying breath weapon into its bite attack to be used along with it. This still counts as a use of the breath weapon and you must wait 1d4 rounds before using the breath weapon in any way shape or form again. Channeling the breath weapon is a swift action.
Disease Body: At 18th level all of the Styx Dragon's natural weapons can transmit diseases as his tail.
Tail sweep:
Pestilence:At 19th level the Styx Dragon can contaminate anything it touches. As a fullround action the Styx dragon can "rub" the area where he's standing or a number of objects equal to his Con modifier. The next creature steping on that area or touching the object willingly receives a disease as if hit by the Styx's dragon natural weapons, same Fort Save to resist. The disease must be chosen when the Styx Dragon rubs. The effect is permanent but each contaminated square /object can only try to infect one creature per HD. A rogue can spot and safely "clean" an object with his trap sense, search and disable DCs are 10+HD+Con modifier.
Disease perfection Su: At 20th level, the Styx dragon's affinity for disease has reached it's peak. From this point on, the dragon's disease based abilities* affect even those normally immune to them. The dragon now bypasses any immunity derived from type, race, class, or anything else besides being a Styx dragon (or summoned by a Styx Dragon). Styx dragons are still immune to each other's diseases. In addition, anything that is not normally immune to disease receives no save and the saves on the disease are now equal to the save of the dragon's breath weapon.
*The abilities that disease ascension and perfection apply to are the dragon's tail blades, its SLAs, and any spells it can cast due to the class.

Comments
[spoiler]
The Styx Dragon can't fly, but it swims and burrows quite well. It has a powerfull array of SLAs and disease abilities to back up it's melee-grappling abilities and bard-sorceror spellcasting.
If you feel like playing an aquatic dragon that lays down plagues upon his oponents, the Styx Dragon's for you!
[/spoiler]
In addition to the features described herein, there are new feats to enhance the Styx dragon's disease based abilities. (Credit to Hyudra)
Extraordinary Disease [Monstrous]Your disease works in a manner above and beyond that of other creatures of your type.
Prerequisite: A natural weapon that can transmit disease, 13 Con and 6HD, at least one of which must be a level in a monster class.
Benefit: Choose one of the following from the list to enhance your poison:
[spoiler]
- Pathogen: Each time the victim fails a save against the disease (including the initial save to find if the disease was contracted), the DC is increased by +2.
- Rapid Onset: The Disease now has an incubation period of 1d3 rounds. This may be taken a second time, reducing the incubation period to 1d3-2 rounds.
- Scourge: The victim must save against the disease twice as often (ie. from every 24 hours to every 12 hours). This option may be taken multiple times, halving the amount of time the victim must save each time it is taken. (from 24 to 12, 12 to 6, 6 to 3, and so on).
- Fever: Once the poison enters the victim's system, the victim displays a rapidly progressing fever. From the point the victim fails the saving throw up until the time the disease is removed, the victim is Fatigued. Once the disease is incubated, the victim must make a fortitude save on any given hour or Exhausted, instead. (DC is 10 + ½ creature's HD + creature's Con)
Once the disease has incubated, the victim must save or be nauseated/confused (again, as appropriate to the disease) on any given hour.
- Miasma: After a disease has finished incubating, a contagious vapor begins leaking out of their nose and mouth to taint the air around them. The disease effectively becomes inhalation and contact based, transmitted with the victim themselves as the origin point. Any infections transmitted in this way have the traits of the original disease, but with only a 50% chance the new victim will also show signs of the miasma.
1d3 rounds after a victim afflicted with Miasma dies, the miasma begins consuming their body, filling all adjacent squares with the inhaled version of the disease.
- Blight: The disease becomes potent enough to affect targets that are normally immune, as the individual elements in the disease produce byproducts that consume, occlude or taint even inanimate matter or energies. The Disease can now affect any creature that cannot produce the disease itself, including those creatures that are typically immune or that lack constitution scores. The effects of the poison are halved when affecting such opponents, rounding down. Diseases that would deal Con damage to creatures with no Con score deal Cha damage instead.
[/spoiler]
Special: This feat may be taken multiple times, choosing a different option each time (or choosing options that specifically allow multiple instances).
