Ivan Dreyar

Ivan Dreyar is the father of Laxus Dreyar and the son of Makarov and master/founder of the Raven Tail Guild.

Background
He implanted dragon Lacrima in his son as a child, since Laxus had been weak at that time. Ivan only implanted the magic in his son's body because he knew that it would be worth a lot later. From Laxus's words earlier in a flashback, Ivan was once a member of the Fairy Tail Guild before being banished. Laxus seemed very distraught by his banishment.

Ivan shows many signs of insanity during his small appearance. He seems obsessed with Fairy Tail enough to name his own guild a similar name. He also seems to enjoy killing things as he turns ravens into shikigami and then biting their heads off. Ivan also calls everyone a silly name, as he calls Gajeel "Gajeel-chan" and Laxus "Laxus-chan".

Fighting Festival arc
Ivan contacts Gajeel Redfox through a shikigami commanding him to be paitent in his quest for revenge against Natsu Dragneel so he can defeat Laxus. Later he explains to Gajeel that Laxus is a fake Dragon Slayer and he has been using Gajeel as a spy, but not knowing that Gajeel is truly a double agent for Fairy Tail.

Magic & Abilities
Ivan seems to have strange magical abilities that manipulate things into shikigami. Given his family's great magical history, it is possible that he is a very powerful wizard.
