I gotta admit, I really like the idea of Lucy being the light of Fairy Tail and I kinda think she deserves it too. This is like my mini rant on her awesomeness as well as a little on after the guild disbands. I honestly wouldn't be surprised if Lucy becomes guildmaster someday.
There was a reason Lucy was known as the Light of Fairy Tail. There were many reasons actually.
She was just so accepting. She had been hurt by so many people who were now her guildmates. Gajeel, Laxus, the rest of the Thunder God Tribe, even Juvia. They had done horrible things to her and her family, and yet, when they realized how awful they had been, she was always the first one to accept them, welcoming them in with open arms.
She was beautiful too, and not just physically, although nobody could deny that Lucy was stunningly pretty. Her beauty was on the inside too. She was so cheerful and she loved everyone in Fairy Tail. Sure, she could be a little, erm, harsh with Natsu and the rest of her team sometimes, but she never crossed the line, and everyone admitted they usually deserved it.
When she went on missions with team Natsu, she was the one who spoke to the client and gathered the information they needed to know. She was the one who booked the hotel, making sure to get three rooms- one for her and Erza, one for Natsu, and one for Gray. They had never tried to pair up Natsu and Gray. It wasn't worth the risk. Lucy was the one who packed medical supplies, a map, and other necessities.
She worried for everyone in the guild, and she took care of everyone. She teamed up with Mira to get Gajeel to kiss Levy because she knew her blue-haired friend spent a lot of nights crying because of him. It worked out unbelievably well since Lucy knew secrets Mira would never have been told for fear of it being used against her.
Most of all though, Lucy was the one who held them all together, and she was the one who rebuilt them after they crumbled. After Fairy Tail disbanded, Lucy went to Tenrou. She trained there for a year, then went home to Magnolia, where Master Mavis helped her restore Fairy Tail. She tracked down all of the old Fairies, sending Loke out to retrieve them. She knew what Master hadn't. She knew that no matter what happened, all of Fairy Tail needed each other. She did what nobody else dared to do. She pulled them all back together, and when Master Mokarov decided to stay in retirement, it was decided that she would be the next Master.
After the guild had been back together for two years, Natsu still hadn't come back. She left on a 3 month journey, and brought Fairy Tail's salamander home.
She loved them all, and they loved her.
She truly was the Light of Fairy Tail.
