Power Progression

Background / History

Xi Feng was a mercenary before being transported into the world of Fairy Tail. He awakens in a smaller body inside the Tower of Heaven and receives memories identifying him as Erza’s older brother. The two had depended on one another since childhood, lived homeless, and eventually been captured as slaves 1.

Before his awakening, Xi Feng had taken responsibility for Shu’s failed escape plan and suffered severe punishment. His presence changes Erza’s circumstances: she retains her left eye. Jellal helps Erza rescue him but is captured while holding off their pursuers 1.

Xi Feng starts the slave rebellion by killing an abusive Mage with a sharp stone. After Rob sacrifices himself to protect Erza, Xi Feng awakens Unlimited Blade Works and defeats the tower’s troops. He and Erza then discover that the brainwashed Jellal has embraced Zeref’s world; Xi Feng takes a magical attack intended for Erza 1 2.

After leaving the tower, Xi Feng travels with Erza, takes in Kinana while she is still a snake, and invites Wendy to accompany them. His knowledge of the original story influences his choices: he keeps Wendy with him to spare her the sorrow associated with the false Cait Shelter. He also recognizes the Edolas counterpart of Jellal and stops Erza from attacking him 2 3 4.

Appearance

• Hair: Black 15 20 30.
• Face: Repeatedly described as handsome 5 16 20.
• Guild mark: A gray Fairy Tail emblem on his right arm 5.
• Early appearance: Initially occupies a child’s body; later passages describe him as a man 1 20.
• Combat forms: Can appear in full crimson armor through Boosted Gear’s Balance Breaker 12 50.

Personality

Xi Feng combines a mercenary’s ruthlessness with an affectionate, protective manner toward his companions. He kills Tower of Heaven soldiers, dark Mages, and bandits without hesitation, but comforts Erza, encourages Wendy and Kinana, and offers Bisca a place in Fairy Tail after learning why she stole 1 6 14 16.

He treats Fairy Tail as a family rather than merely an employer. The guild’s warmth contrasts with his former life, and he accepts responsibility for retrieving Natsu and Happy from an unauthorized S-Class mission even when he feels like a babysitter. During the Phantom Lord conflict, he rejects Lucy’s need to thank him because protecting a fellow guild member is a family obligation 5 27 34.

In battle, he is composed, observant, and eager to test his limits. Makarov notices that his reactions and awareness do not resemble those of an ordinary child. Xi Feng welcomes Laxus’s challenge and becomes excited rather than intimidated when confronted with Gildarts’s superior strength 5 9 12.

His gentleness does not exclude manipulation. To draw out Kagura’s potential, he falsely claims to have killed Simon, provoking an attack that awakens her magic. He later admits the deception and respects her decision to continue searching for her brother instead of joining Fairy Tail 15.

Abilities & Skills

Perfect Projection Magecraft

Xi Feng creates weapons and supernatural equipment rather than simply retrieving stored objects. His projections can reproduce Noble Phantasms, God-Slaying Sacred Gears, and Zanpakutō 1 5 12.

• Full-strength reproduction: Projected Noble Phantasms retain the originals’ rank instead of being downgraded 1.
• Inherited techniques: Projecting a Noble Phantasm gives him instinctive knowledge of its movements and finishing techniques, demonstrated with Monohoshizao and Sasaki Kojiro’s swordsmanship 6.
• Continuous consumption: Maintaining projections steadily drains his magical power, limiting prolonged battles 1.
• Life-force cost: Forcing a projection without sufficient magical power directly consumes his life force 1.
• High-cost objects: Excalibur, Boosted Gear, and powers that interfere with life or time place especially heavy demands on him 5 12 30 34.

Unlimited Blade Works

His first awakened magic transforms the surroundings into a red wasteland filled with swords, flames along the horizon, and enormous interlocking gears 1.

• Manifests numerous swords and launches them at enemy troops 1.
• Defeats the Tower of Heaven’s Mages and soldiers in a single overwhelming assault 1.
• Leaves him exhausted when the manifestation ends 1.

Swordsmanship and Close Combat

His original body’s mercenary skills remain accessible despite his reduced size. Projected weapons further expand his sword techniques 1 6.

• Bullet interception: Deflects Bisca’s gunfire with Monohoshizao 16.
• Unarmed fighting: Easily counters Gray and Natsu and defeats the Panishu Brothers with throws and strikes 8 21 25.
• Instruction: Trains Kagura for a month, helping her become capable of protecting herself 14 15.
• Limits: Describes his swordsmanship as below master level. Ikaruga’s invisible slashes initially wound him and destroy his projected blade 14 42.
• Teaching limitation: Does not know how to teach magic directly; his limited command of the world’s written language also prevents him from helping Kinana learn it early on 5 14.

Blade of Gale

• Wind Barrier: Blocks the Evil Soul Mages’ combined attacks and counters lightning attacks from Nickel and Laxus 6 9.

• Gale Breath Slash: Delivers dozens of slashes within a second 6.
• Forward Slash: Enables swift approaches and repositioning; he uses it in his victory over Laxus and against Kagura’s attackers 9 14.

Excalibur

The projected Sword of Promised Victory releases an enormous blade of light 5.

• Its output impresses Makarov as an S-Class spell and forces him to defend with Three God Pillars 5.
• Breaks through Nickel’s Thunderclap Bomb and ends their battle 7.
• Both projecting the sword and releasing its attack can exhaust Xi Feng’s reserves 5.

Boosted Gear

A red, dragon-claw-like gauntlet projected onto his left arm. Its repeated “Boost” activations double his strength at regular intervals 12.

• Stacking enhancement: Successive boosts increase the force of his attacks enough to push Gildarts backward 12.
• Explosion Dragon Shot: Fires a sphere of magical energy; Gildarts destroys it with Crash 12.
• Balance Breaker: “Welsh Dragon Over Booster” manifests full red armor 12.
• Scale Mail: Uses the crimson armored form again against Laxus during the Battle of Fairy Tail 50.

• Final Scene—White Emperor Sword: Uses this finishing technique as Jellal unleashes Seven-Star Sword 44.

• Breaks Erigor’s Demon Wind Barrier 23.
• Shatters Freed’s Magic Formula, freeing the trapped guild members 47.

Cup of the Underworld

A projected God-Slaying Sacred Gear capable of overturning the natural laws of life. Its described functions include healing, resurrection, and granting a degree of immortality 30.

• Demonstrated use: Resurrects Ur despite her having left no body behind 30.
• Life link: Ur’s resurrection links their lives; Xi Feng explicitly states that if she dies, he dies too 31.
