Laxus Dreyar

Laxus Dreyar is the grandson of Makarov Dreyar, the son of Ivan Dreyar and the main antagonist of the Fighting Festival arc of ''Fairy Tail. He is also a Second Generation Dragon Slayer, due to a Lacrima his father implanted in him when he was young. ''Introduced as selfish, extremely arrogant and determined to do whatever it takes to become the new leader, Laxus traps the entire guild in a massive deathmatch to make his grandfather hand it over. Through flashbacks, it is revealed that his father was expelled from the guild when he was younger, after which he grew tired of being seen as only the Master's grandson; in the end, all he wanted was to be acknowledged as his own person.

Ultimately, it takes the combined strength of Natsu Dragneel and Gajeel Redfox to defeat him and he is expelled like his father before him, though he rejoins the guild later in the series.
