Background / History

Leo entered the CKHX-3819 Blood Trial as Thunder Star Mountain's Thunder Wing Giant representative. Although such a participant would ordinarily operate in the Northern Domain, he instead appeared in the Eastern Domain as part of Thunder Star Mountain's alliance with Cangming Valley, Pesili's Realm Lord family, and other Special Elites. He openly declared his intent to wipe out the Blood River Squad. 30 31

His innate Thunder Domain initially made him a dominant battlefield presence, but Li Long defeated him after stabilizing a higher-level Ice Snow Domain. Leo took Li Long's dismissal personally, especially the implication that Lei Ao—not Leo—was the true Thunder Wing Giant worth facing. This defeat drove Leo to pursue a domain of his own. 33 34

During the later conflict over Kadi's death, Wu Sheng attacked Leo's soul and successfully branded him with Mind Control. Leo's Innate Life Core strongly resisted the process, nearly causing backlash against Wu Sheng, but Leo ultimately became Wu Sheng's controlled servant. 38 39

Wu Sheng later evolved Mind Control into Soul Control, eliminating the prior backlash risk and granting Leo greater autonomy while preserving absolute loyalty. Under Wu Sheng's guidance, Leo comprehended the Wind Domain, allowing him to combine wind and thunder while retaining his Thunder Wing Giant racial advantages. 43 44 47

After the Blood Trial, Leo continued to act as Wu Sheng's frontline protector in the Soul Oath Land. He blocked a D5-grade laser cannon while wearing a D6-grade Machine Clan battle suit, fought beside Wu Sheng to seize a High-Grade Soul Crystal, and assisted in capturing Lava Giants for profit. 85 88 95

Appearance

Leo normally possesses a roughly two-meter humanoid form, but his true Thunder Wing Giant body is a cyan giant whose size increases dramatically as his strength grows. 31 35 85

• Cyan-skinned giant in transformed form.
• Purple wings covered in deep-purple lightning runes. 30
• Violet lightning arcs continuously around his wings and body while fighting. 30 44
• Dense bone-white teeth, described as nearly half a meter wide in giant form. 30
• Recorded transformed heights include roughly 90 meters, over 200 meters, and 900 meters. 31 48 85
• Frequently wears armor, including silver armor and a D6-grade Machine Clan battle suit. 85

Personality

Leo is prideful, combative, and strongly conscious of his Thunder Wing Giant heritage. Li Long's victory and comparison to Lei Ao deeply offend him, motivating him to seek greater mastery of domains and Source Laws. 34

Before being controlled, he is arrogant toward weaker opponents and enjoys intimidating them with his overwhelming racial talents. He can nevertheless assess a battlefield clearly, such as recognizing Li Long's depleted energy and reassuring his allies after their retreat. 31 34

Under Soul Control, Leo remains capable of independent thought, personal desires, and concern. He warns Wu Sheng about Thunder Wing Giant Clan activity targeting Blood Sun City, worries about Wu Sheng's safety, and offers practical advice during their travels. 56 77 105 His loyalty to Wu Sheng is compulsory, however, and he privately resents being ordered to serve as a shield. 85

• Must be manifested in Leo's true form. 44

Innate Life Core

As a Thunder Wing Giant, Leo possesses an Innate Life Core that grants exceptional energy reserves and resistance.

• Gives him far greater Primal Force and psychic-power reserves than ordinary races. 34
• Allows him to outlast Li Long in prolonged combat, even after Li Long holds an initial advantage. 55
• Resists soul techniques and made Wu Sheng's original Mind Control attempt unusually dangerous. 39

• If Wu Sheng cancels the primary imprint, Leo regains freedom; if Leo dies, the control slot returns to Wu Sheng. 122

Trivia

• Leo's name is rendered from the original Chinese 雷欧.
• His transformed skin remains cyan despite his Wind Domain, confusing other trialists who expected a Thunder Wing Giant with a domain to display different racial coloration. 48
• Leo is capable of speaking the Prison Clan common language but cannot communicate with the captured Elf Woman, who speaks the human language. 48
• Although he has racial advantages and dual-domain potential, Leo's borrowed Wind Source Law insight is insufficient to overcome Lei Ao's superior Thunder Source Law comprehension. 74
