During Xeno Trunks' investigation of the anomalies in the game world of Super Dragon Ball Heroes caused by the "the menace", as part of hiding his identity from the locals in Hero Town, Trunks had Leggings create a new high-tech sword to wield in his costumed identity as the Great Saiyaman 3 as his original sword could ruin the disguise. The sword is durable and sharp enough to cut through the game world Cooler's Bio Suit and block his punch while in his Fourth Transformation, indicating that its strength is comparable to his original blade, though when it blocked Cooler's punch it emitted energy that forms a protective barrier around the blade.
In Chapter 1 of World Mission, Great Saiyaman 3 wields the sword while protecting Beat from the game world Cooler who had escaped to Hero Town due to an anomaly created in the game world by "the menace". After using the sword to block a punch meant for Beat, Great Saiyaman 3 uses the sword to kill Cooler with a Burning Slash, like Future Trunks did to Frieza with his sword in the main timeline.
