Background / History

Welt recognizes Yan Huan's swordsmanship as resembling that of Fu Hua, a friend from his homeland. Yan Huan's claim to have commanded the Hyperion confirms to Welt that he is someone from that world; Welt is visibly shaken by the reunion and later expresses happiness that Yan Huan has become a companion again in another universe 8 21.

When Fu Hua appears on Jarilo-VI, Welt warmly greets her as “Alliance Leader.” Her presence is especially meaningful to him because she is someone he personally knew, unlike the local versions of Seele and Bronya 112.

Welt is later identified as the original creator of the Titan mechs. Although another Welt is present during the Xianzhou crisis, he rejects the distinction between “original” and “replica” as far as those who know the other Welt are concerned 262.

His past is described as including work in animation and leadership of a terrorist organization that once stirred conflict across an entire world 869.

Personality

Welt is generally analytical, cautious, and protective of the Express crew. He assesses threats before acting, advises others to retreat from dangers beyond their ability, and prioritizes sealing Stellarons over his own safety 262 692 721.

He can also be deeply affected by memories of his homeland and past actions. After being shown footage of his conduct on the Luofu, he isolates himself in distress; later, stress and repeated stimulation contribute to illness and detachment 227 243.

During the Luofu incident, the effects of Yan Huan's “Wangzai Awesome Candy” make him unusually aggressive, arrogant, and impulsive. He intimidates Tingyun, severely injures Cloud Knights, and threatens Yukong before Yan Huan stops him 214 219.

Story Role / Major Arcs

Herta Space Station

Welt witnesses Yan Huan's defeat of the Doomsday Beast and recognizes both the precision of Yan Huan's swordsmanship and his connection to the Hyperion 8. He supports Yan Huan's place among the Express crew and reflects positively on Yan Huan's changed circumstances 21.

Jarilo-VI

Welt advises Yan Huan to act with more caution while pursuing the planet's Stellaron 100. He also reunites with Fu Hua, someone from his homeland 112.

Xianzhou Luofu

Welt personally investigates the Luofu's abnormal signals and acquires a Herrscher core from Yan Huan 212. Under the influence of Yan Huan's candy, he becomes confrontational and violent toward Cloud Knights and Yukong, culminating in a duel with Yan Qing where he dominates the battlefield with gravity 213 224. After reviewing recordings of these actions, he becomes ashamed and withdrawn, then returns to a more cautious approach to the Stellaron Hunter investigation 227 228.

Penacony

Welt takes an investigative role in the Dreamscape, works alongside Acheron, and questions both the Family's security and Sandstone's motives 670 692 702. He opposes the Dream Master's idea of “perfect harmony” and participates in the conflict surrounding Penacony's hidden power structures 741 742.

Onfaros Investigation

After Yan Huan and Dan Heng become unreachable, Welt assists Sunday and Herta at Herta Space Station. He helps install Herta's Magic Mirrors and worries that Onfaros may hold a sealed Great-Eradicator whose release would create a major threat 1495 1498 1499.
