Gretor is a bipedal seven-foot-tall reptilian with opposable thumbs and blades all over. He is similar in appearance to a Hork-Bajir (http://media.photobucket.com/image/hork-bajir%20drawing/DevHalena/horkbajir_final.jpg)
He is quiet and observant, curious and stealthy. These traits helped him survive in the Amazonian rainforest for so long without being discovered by humans.
He carries nothing. His only weapons are his blades, and he is reluctant to use those.They are nonretractable and very sharp. Of course, the ferocious appearance generated by these blades doesn't help when seeking assistance or information.
He used to live in the Amazonian rainforest before the humans tore his tree down. He then stowed away on a train going to another forest, where he has lived ever since. However, he is discontent with his new life and is constantly seeking adventures and taking risks. He has been spotted occasionally by humans, resulting in the legend of the Lizard Man, which is similar to that of Bigfoot or Nessie.
