Appearence
Jellal is a young man whose most prominent features are his blue hair and a red tattoo above and under his right eye, which he has had since his childhood. Jellal himself is seen in much darker clothing, with his attire consisting of a whitish blue shirt under a hooded dark blue coat with light blue edges, two strings with shield-shaped pendants hanging down from the hood and a prominent golden symbol on the left part of the chest, reminiscent of Fairy Tail's mark, plus simple, loose, dark pants tucked inside laced boots. As Metal Jellal, his appearance is that of a large, blue, heavily-armed mechanical dragon, with two eyes lined up vertically on his head. He has several long spikes on his upper body and many smaller ones running down his back and his long, curved tail. He has a flamethrower as his right hand, and his left hand has four fingers with claws that can be launched. He has no legs in this form. Instead his lower body is attached to the Whale Shark with several thick cables. Under these clothes is a special fighting suit for melee combat, designed for his Meteor spell, revealing his toned and muscular body.

Background
Erza grew up in Rosemary Village, the same place where Kagura and Simon lived as children in the Land of Haro. When Rosemary Village was attacked by a Zeref-following cult, Erza managed to save Kagura from capture by hiding her inside a crate, but got caught herself as a result. She was enslaved by the cult and forced to build the Tower of Heaven, a structure developed for the purpose of resurrecting the Dark Mage, Zeref. She was imprisoned together with several other slaves, most of them were children. Among these children were Jellal Fernandes, Shô, Simon, Wally Buchanan, and Millianna. While they were asking each other for their names, she said that her name was just "Erza", so Jellal decided to give her the surname "Scarlet" after her scarlet hair so they would never forget it. Overtime, the Ten Tailed Beast destroyed the incomplete Tower of Heaven and the Zeref-following cult in the Powerful Rampage letting Erza and all their friends to escape from the tower. After washing up on the shores, Erza made her way to and joined the Fairy Tail Guild.[5] She habitually began to wear armor and acted distant from the other members. After Gray, who tried picking fights with the reclusive Erza, saw her crying by herself and questioned why, she began to open up to her guildmates more. To get the data he needed, Jellal was able to copy the Data of the Shinobi and Wizards.
