@Medik
You are correct in assuming this will not be very "toony", but I would also like to keep people as close to their "normal" character as possible.
You would need to wear pants and many people may look at your strangely if you're not wearing a shirt unless you're at the beach. You can retain your normal childlike persona and have an equivalent height but you'd have to expect the NonPlayer characters to treat you like a child. You are of course allowed to adjust your height in age if that is just not the type of roleplay you'd be looking for in this instance.
Jackals would translate to Lucavune on Planet, a species consisting of members of the canidea finally: wolves, dogs, foxes, and many other creatures including jackals. Lucavune have the innate species power of Pact Thought. Essentially your psychic, with the default ability to have touch telepathy with other people who have Pact Thought, and one other ability that tends to favor telepathy or telekinesis. Exceptions abound, though. Ryan himself has what would be defined as "far sight", a very present oriented form of clairvoyance.
Remember when making these design decisions your not creating a character for a world, but deciding how your character would be changed to fit the world so as not to spook the locals when your visiting. As a character you're supposed to know that your not from around town, essentially.

What I just said to Medik says it best. Raf himself is taking his friends to visit "his world". So even if you aren't your default self, which just as Medik can choose to alter his child like age you are free to choose, you are still designing a tourist who is visiting foreign world and has taken on features native to that world to avoid rising questions from the locals.
I guess a species list would be appropriate. I was just hoping to have part of the tour being explaining things in person as much as possible.
Lucavune: Structured after the canidae family Lucavune resemble wolves, foxes, and all subspecies derived from the two. Lucavune as a species possess a form of psychic ability known as Pact Thought; Pact Thought touch telepathy with other Pact Thought gifted, and one other power which tends to favor telepathy or telekinetic.
Fenine: Structured after the felidae family Fenine resemble cats, domestic and greater. Fenine posses a form of magic known as Bio-Runics. Bio-Runics allows one to both inscribe and activate runes; it comes in several forms of elemental specifications.
Tucotter: Structured after the musteloidea super family Tucotter resemble not only ferrets, otters, and badgers but also raccoons, skunks, and red pandas. Tucotters possess a subtle form of innate cybernetics known as Bio-Cybernetics. Bio-Cybernetics allows one to interface with properly equipped technology like a form of blue tooth, and carry several software applications within their own minds.
Brendar: Structured after the ursidae family Brendar resemble bears. Brendar possess a form of psychic ability known as Bio-Ecto. Bio-Ecto grants enhanced sixth sense, and one other power favoring clairvoyance or psiometabolism.
Siles: Structured after the pinnipedia super family Pinnipedia resemble seals and walruses. As a species, Siles have Sea Breath which very simply means they can breath underwater.
Hyetuar: Structured after the hyaenida family Hyaenida resemble hyenas. All Hyetuar are Tuars, which is to say they have a normal male athro torso growing out of a female feral body... yes, you did read the gender right, but given the nature of the forum we're not going to be getting into the social ramifications of that issue in this roleplay.
Monga: Structured after the herpestidae family Meegoo resemble mongoose and meerkats. All Monga are a special form of Naga, possessing a snake like lower body with a soft scaled belly but otherwise furred coat.
Hybrids do exist as well, though in appearance they look like only one parent species and tend to be mules, meaning they can't be parents themselves. They do possess the powers of both parent species, though.
