Cerberus the Hellhound (Battle Pet|85,000 Jewels)

Name: Cerberus the Hellhound
Pet Type: Hellhound
Gender: Male
Height: 1/2m x 1/2m at D-C rank, 3m x 3m at B-A rank, 6m x 6m at S-SS rank
Appearance: Cerberus is a rather interesting creature. Upon being first acquired, Cerberus is little more than a small three-headed puppy. His fur is jet black and he bears fiery orange accents on his paws. A fiery red glow shines from within his eyes and mouth. Clamped around his forepaws, neck, and and rear thighs are metallic banding. Starting at the crown of each of his heads, a trail of fire burns perpetually along his spine and ends at the tip of his tail. At this stage of his development, the fire is merely a soothing warmth to any who touch it, though as Cerberus grows he is capable of making the flames generate scalding hot effects to those who he does not consider an ally. At the adolescent and adult stages of his growth, Cerberus becomes large enough to safely bear his owner and one of their allies upon his back and allow them to ride him.
Abilities:

• Hellfire Aura (gained at C-rank, can be upgraded to A-rank|spell rank cost + sustain)- Cerberus wreathes himself and any allies he happens to be carrying in hellish flames. These flames deal no damage to Cerberus's passengers, but deals burns consistent with Cerberus's current rank to any opponents that come within 1m of him. This ability lasts for as long as Cerberus has the MP to maintain it and has a 4 post cooldown.
  
• Triple Inferno (gained at C-rank, can be upgraded to A-rank|spell rank cost)- Cerberus will breath a stream of fire from each of his three heads at an opponent. The streams move at a speed and range consistent with Cerberus's current rank and deal damage reflective of Cerberus's current rank. This ability has a 3 posts cooldown.
  
• Passenger Carrier (gained at C-rank|Passive)- Cerberus is capable of bearing his owner and an ally upon his back. This passively reduces the travel count for both passengers by 40%.
  
• Unholy Attributes (Passive)- Cerberus gains increasing physical capabilities as he grows.
  

  Spoiler:

In order to increase Cerberus's rank, you must do a training thread in the same manner as if you were training a new spell.
