A few members of the group seemed to have been turned into animals, which rendered them almost useless in combat. The ones that were still able to fight - an Ave, a Gryphon, and a Phoenix - started launching attacks at him. He quickly healed a bunch of the damage dealt to him with a potion, then knocked out Backstabs with a single hit, thankfully not killing her. This made her change back to her original form. It was obvious that this ninja was much more powerful than their previous opponents. 

 Trey tried to charge at the human, but he lost his balance and fell on the ground, missing completely. He was having quite a bit of trouble getting used to his new form, and he was sure the others were struggling just as much. He noticed that the katana was lying on the ground, which would give someone a perfect chance to pick it up.
"Somebody grab the sword!" Trey said as he tried to get back on his feet.
