The Dragon ball manga called Super Dragon Ball Heroes is known for its wild content that can differ greatly from established Dragon Ball lore, and in one such story, Future Trunks found himself a new sword. However, this sword is no ordinary sword; it’s a special weapon called the “Key Sword,” and yes, it looks like it’s fresh out of Kingdom Hearts.
In Super Dragon Ball Heroes: Dark Demon Kingdom Quest! chapter 13, The Time Patrol (made up of the alternate universe counterparts of beloved Dragon Ball characters) is attempting to defeat a group known as the Dark Army, who are currently in control of holds great power thanks to the dark dragon balls and is holding the Supreme Kai hostage to Time.

Trunks’ key sword opens the portal and fights the darkness
The Key Sword is said to be capable of opening the six gates of Hell that the enemy has used to strengthen their barrier, ensuring that no one can interfere with their plans. While the others were sent to fight the Demon Gods who acted as anchors for the barrier, Trunks was left alone to hold the gate open so they could return.

Trunks receives a vision of what the Supreme Kai of Time went through and is furious, transforming into Super Saiyan 3 and attacking with the Key Sword. With one attack, Trunks is able to dispel the darkness that is controlling her and freed her from the Dark Army’s control. Without the Supreme Kai of Time under their control, the Dark Army and its leader, Mechikabura, would have been much easier to defeat, dealing a heavy blow to the enemy.
In addition to being a sword that looks and functions like a key, the Key Sword also has the ability to open interdimensional gates like the gate leading to Hell and can dispel the darkness that covers the heart. opponents, much like the Keyblade of Kingdom Hearts. Even the story’s premise of jumping around timelines is somewhat similar to the world-hopping plot of Kingdom Hearts. Trunks (in his Super Saiyan God form) eventually uses the further enhanced Key Sword to seal Mechikabura forever, allowing him to banish the darkness tainting the timeline.
As a sword used to defeat a divine being, it is a major upgrade over Future Trunks’ regular sword, which doesn’t really have any special properties. Unfortunately for Trunks, the Key Sword seems to have returned to normal after the battle, so he won’t have this incredible power in the future. Fans probably never expected it Dragon ball to give Trunks a Keyblade from Kingdom Hearts, but that’s just how Super Dragon Ball Heroes plays out–it’s unpredictable.
