The next one for me is Erza Scarlet from Fairy Tail. In every sense of the word she is as beautiful as she is deadly. Erza has an armor for every opponent.
Heart Kreuz Armor: Made by the popular fashion brand Heart Kreuz specifically for her, this is Erza's casual armor.
Heaven's Wheel Armor: Erza is able to summon a large amount of swords (roughly more than 200), and launch weapons at her opponent(s) in a variety of different ways. The armor is meant to be used for facing multiple opponents.
Black Wing Armor: This armor increases Erza's offensive capabilities, and she uses it in conjunction with any number of weapons to deal her enemy great damage.
Flame Empress Armor: This armor lowers the destructive power of flame attacks against her by 50%.
Giant's Armor: : In this armor, Erza is able to increase the strength of her throwing power.
Adamantine Armor: This armor is the ultimate, high-level defensive stance. While wearing it, Erza is able to withstand the Magic beam fired by the Phantom Lord's Jupiter Cannon, despite her receiving injuries and the armor breaking in the process.
Purgatory Armor: It is one of Erza's most powerful armors, and before Ikaruga, she said that "None had seen the armor and lived to tell the tale." Its true power is not seen immediately as it was destroyed almost instantly in the fight with Ikaruga, but it was seen again in the fight with Azuma, where it was heavily damaged by Azuma's attacks.
Mere Cloth: This is not an armor but is the most flexible outfit Erza has, she has no defense what so ever but 100% agility and relentless attack capability.
Lightning Empress Armor: This is an armor that lowers the attack damage of all lightning attacks aimed at the wearer.
Flight Armor: This armor increases Erza's speed dramatically, to the point where she could match Erza Knightwalker's speed while the latter was using Silfarion. She was also able to keep up with Racer despite being under the effects of his Slowing Magic.
Robe of Yuen: This armor has elastic properties which allows it to stretch without being damaged in any way. It prevented Midnight's Reflector Magic from binding Erza.
Morning Star Armor: This armor is able to shoot energy blasts by concentrate magic power in two twin swords
Armadura Fairy Armor: It is Erza's strongest armor as declared by her counterpart, Erza Knightwalker. This armor has the name of the Fairy Tail Guild to symbolize Erza's pride of being a member of Fairy Tail.
Sea Empress Armor: According to Lisanna, this armor nullifies water attacks. It has been shown to be able to withstand Juvia's water spells.
Seduction Armor: I have no idea about this armor, I'm not this far in the series since I only watch it in english ^_^
Fairy Tail Farewell Armor: is a special armor of Erza's that she uses during Fairy Tail's farewell ceremony when a member leaves.
