Here's Metaxo's level 12 sheet. I noted down at the bottom where it's listed that I'm not really sure how serpent's bite attack and damage is calculated. The description of natural attacks as is leaves it a little ambiguous. Also, for the favored class bonus I took the skill point.

Weapon and Armor Proficiencies: A ranger is proficient with all simple and martial weapons and with light armor, medium armor, and shields (except tower shields).
Other Class Features: Favored Enemy [Animal] (+2)
+2 bonus on Bluff, Knowledge, Perception, Sense Motive, and Survival checks against creatures of his selected type. Likewise, he gets a +2 bonus on weapon attack and damage rolls against them. A ranger may make Knowledge skill checks untrained when attempting to identify these creatures.
Favored Enemy [Magical Beast] (+4)
+4 bonus on Bluff, Knowledge, Perception, Sense Motive, and Survival checks against creatures of his selected type. Likewise, he gets a +4 bonus on weapon attack and damage rolls against them. A ranger may make Knowledge skill checks untrained when attempting to identify these creatures.
Track (+3)
A ranger adds half his level (minimum 1) to Survival skill checks made to follow or identify tracks.
Wild Empathy (+7)
A ranger can improve the initial attitude of an animal. This ability functions just like a Diplomacy check to improve the attitude of a person (see Using Skills). The ranger rolls 1d20 and adds his ranger level and his Charisma bonus to determine the wild empathy check result. The typical domestic animal has a starting attitude of indifferent, while wild animals are usually unfriendly.
To use wild empathy, the ranger and the animal must be within 30 feet of one another under normal visibility conditions. Generally, influencing an animal in this way takes 1 minute, but, as with influencing people, it might take more or less time.
The ranger can also use this ability to influence a magical beast with an Intelligence score of 1 or 2, but he takes a –4 penalty on the check.
Favored Terrain: Forest (+2)
The ranger gains a +2 bonus on initiative checks and Knowledge (geography), Perception, Stealth, and Survival skill checks when he is in this terrain. A ranger traveling through his favored terrain normally leaves no trail and cannot be tracked (though he may leave a trail if he so chooses).
At 8th level and every five levels thereafter, the ranger may select an additional favored terrain. In addition, at each such interval, the skill bonus and initiative bonus in any one favored terrain (including the one just selected, if so desired), increases by +2.
Hunter's Bond
This bond allows him to spend a move action to grant half his favored enemy bonus against a single target of the appropriate type to all allies within 30 feet who can see or hear him. This bonus lasts for a number of rounds equal to the ranger's Wisdom modifier (3). This bonus does not stack with any favored enemy bonuses possessed by his allies; they use whichever bonus is higher.
Woodland Stride
Starting at 7th level, a ranger may move through any sort of undergrowth (such as natural thorns, briars, overgrown areas, and similar terrain) at his normal speed and without taking damage or suffering any other impairment.
Thorns, briars, and overgrown areas that are enchanted or magically manipulated to impede motion, however, still affect him.
Detect Psionics
All psions, regardless of their chosen discipline, gain the ability to use detect psionics at will, as long as they maintain psionic focus. This does not require any power point expenditure, and the power cannot be augmented.
Burst (Discipline Talent)
This power increases your land speed by 10 feet. This adjustment counts as an enhancement bonus to speed.
Detect Teleportation (Discipline Talent)
You sense the use of any effects of the teleportation subdiscipline within the area. You sense the use of these powers whether or not you have line of sight or line of effect (although a force effect prevents this detection). When you sense the use of an appropriate power, you know the direction in which the power was used, though not the distance or the exact effect.
Nomad's Step (Discipline Ability) [30 ft.]
At 2nd level, as long as you maintain psionic focus, as a standard action you may teleport to a location up to 15 feet away. You must have line of sight to the location and you can bring along possessions that amount to as much as a medium load. The distance increases by 5 feet every psion level thereafter.

Appearance:
Metaxo is an Ophiduan, muscular and lean. Tall by human standards but average for Ophiduans. His scaly skin is a very dark shade of green and his slitted eyes are a vibrant yellow as typical for his race.
Background/Personality:
Metaxo grew up on the south side of the Rhivian continent. Driven by the Ophiduan need to constantly better himself and prove his worth, Metaxo looked to the wide world around him for the endless challenges it contains. He's crossed the continent from Zanjinhon to Vanderheim, from the frozen north lands to the torrid south. He hones his skills in the wilderness and learns from the different civilizations of Rhivia, all in the pursuit of personal excellence. The only place he's avoided is Rhivalius, but he has plans to delve into the haunted ruins when he has the skills and weapons necessary to battle the specters and spirits that call that cursed place their home. To earn some extra income, he dabbles in cartography and carrying trade goods. He has mapped out much of Rhivia and has gained some acclaim as a wilderness guide for travelers or merchants which has lead to his being sought out for the expedition into Azagan. Metaxo's motivation is personal excellence. He is not trying to save the world per se, so much as he wants to overcome the challenge that the otherworldly scourge represents.
