“You’re good…but I’m better”  
Having gone through intense training for almost three years, Spike has gained control of his draconic greed, and picked up some skills along the way. Unlike normal dragons, Spike possess a form of magic which enables him to convert his flames into anything he desires, so long as he has enough energy and a strong imagination. This can range from a flame sword to wings. Though he does not like to fight, he will not hesitate to flex his claws when the need comes.  
For the record, this was inspired by Kaneki’s kagune from Tokyo Ghoul.
