A group of rogue dragon slayers could be the main antagonists. They might envy Ignia's power and connection to the Fairy Tail guild. They could start causing chaos and attacking the guild, forcing Ignia to take a stand against his own kind in order to protect his new home and friends in Fairy Tail.
It could be an ancient dragon that has been awakened from a long slumber. This dragon might have a vendetta against Ignia or the Fairy Tail guild for some past transgression.
Perhaps a powerful dark mage who wants to control Ignia's dragon powers for his own evil purposes. He could try to manipulate Ignia by preying on his insecurities or using his friends in Fairy Tail as hostages. This would create a tense conflict as Ignia would have to decide between protecting his new friends and not falling into the dark mage's clutches. The dark mage could also have a group of minions with different magic abilities, making it even more challenging for Ignia and the Fairy Tail members to fight back.
