Sword of Hope from Across Time

The original Sword of Hope drew its power from the surviving humans of Future Trunks's devastated timeline. While that was enough to defeat Fused Zamasu's physical body, the threats encountered in Super Dragon Ball Heroes operate on a scale that dwarfs even godly fusion. The Sword of Hope from Across Time answers this escalation by expanding the energy source from a single timeline's survivors to the combined hope of beings across multiple timelines and eras.

This concept fits naturally within Heroes' multiverse framework, where characters from different timelines regularly interact and combine their efforts against threats that span the entire temporal spectrum. Xeno Trunks, the Heroes version of Future Trunks, operates within a setting where crossing between timelines is routine rather than extraordinary. This gives him access to a network of allies and supporters that extends far beyond what any single timeline could provide.

The technique retains the core emotional principle of the original: it is powered not by raw ki alone but by the genuine hope and trust of living beings who believe in the wielder. The difference is purely one of scale. Where the original Sword of Hope channeled one timeline's worth of hope, this version channels hope from across the entire temporal landscape. The result is a weapon proportionally more powerful, suited to the cosmic-scale conflicts that define Super Dragon Ball Heroes' narrative.
