*Spoilers for those who are beginning to watch Fairy Tail and those who are not caught up to Fairy Tail Season 2/Manga as well*
Gray Fullbuster is an amazing Fairy Tail Wizard! He is one of my favorite characters in Fairy Tail and I honestly just cant get enough of him xD. Gray has gone through many things especially throughout his childhood but that doesn't stop him from fighting in what he believes in. Gray is strong and has a very laid-back vibe but has his little brawls and stripping moments from time to time xD he also has a very lone-wolf vibe sometimes when it comes to his past but thankfully he has his Fairy Tail family to support him and basically make him feel cared about.. (*cough* Especially Juvia *cough* xD)
Before Gray joined the Fairy Tail guild he lived with his Mother and Father until one day a demon from Zeref's book named Deliora came to the town where Gray and his family lived and destroyed and killed Gray's Family. Then came a long a woman named Ur and a young boy named Lyon found Gray and Ur took him under her wing and decided to help teach him Ice Make Magic (she was also teaching Lyon at the time xD) Gray destroyed emotionally by Deliora destroying what he had gave him the will power to learn Ice Make but also made him very vengeful/afraid towards Deliora. Ur taught Gray Ice Make along with Lyon and they were actually living very well together until Deliora appeared once again. Making Gray wanting.to attack him avenging his family but since he was too young and not very powerful he didn't realize he had put Ur and Lyon in danger as well. Ur saw Gray angry, sad and most of all... afraid. She decided to end Deliroas life by usimg a very strong Ice Make Magic called Iced Shell. Deliroa was frozen completely and basically defeated, but with the cost of Ur's life for using Iced Shell uses your body to make the ice you need for iced shell. Gray once again lost someone dear to him and decided to go on alone. Gray then found Fairy Tail and joined the guild as a kid and has been there ever since.
Gray uses Ice Make Magic and now currently in the Manga series he now uses Ice Devil Slayer Magic as well. Gray uses many attacks ( literally a lot xD so im only going to name a few) such as, Ice Make: Hammer, Ice Make: Sword, Ice Make: Cannon, Ice Make: Lance, Ice Make: Shield, Ice Make: Arrow, Ice Make: Blood (he can freeze his own blood making his ice stronger) Ice Make: Unlimited (During his fight against Rufus from Sabertooth) Ice Make: Geyser & Unison Raid with Juvia, Iced Shell (and many more xD) Gray is incredibly strong and overall an amazing FT Wizard and I cant wait to see him grow more in the series.
