During the Fantasia festival, Makarov does a sign that Laxus did when he was younger to show that he’ll always be watching over him. (wikia)
Makarov is a person who is able to love and believe in people, which is the reason Purehito chose Makarov to be the next master. Makarov shows extreme dislike for the Magic Council and all the rules they try to impose on guilds, believing that the skills and Magic of his guild members will not be able to grow if he makes them conform to the rules of the Council. He frequently attempts to balance reprimands from the council and the eccentricity of his guild. Despite this, at times he has to grow in his giant form to stop the insane reveling and destruction of the guild, and acts as a parent to the guild members looking after them and encouraging or inspiring them.
This parent attribute is noticeable when he worries over the destruction that the guild members may cause and tells them to try tone it down. This trait is especially obvious in the Phantom Lord arc when he is disinterested in revenge for the damage caused to the guild, but grows enraged and vengeful when he finds three of his “children” have been hurt.
