Originally a small club, Super Janemba uses his powers to reshape the object into the form of a sword similar in appearance to a Chinese jian. Due to Super Janemba's influence, it is capable of cutting through dimensions and creating dimensional portals by using slashing motions.
The range of the sword is vast. It has the ability to cut enemies from afar through purple blade shaped blasts that can seemingly cleave through anything, easily dealing critical damage to Goku's left arm with only a glancing blow.
Super Janemba uses the Dimension Sword to attack Super Saiyan 3 Goku soon after transforming into his second form, slicing deep wounds into the Saiyan warrior. As Super Janemba is about to deliver a finishing blow, it is destroyed when Vegeta saves Goku with a rain of energy blasts that land on the sword. Though surprised at first, the demon merely laughs about it maniacally before Super Saiyan 2 Vegeta attacks him head on. The sword is never seen again after it disintegrates.
Video game appearances
Super Janemba's Dimension Sword is also present in the Budokai Tenkaichi series and Dragon Ball: Raging Blast 2. Super Janemba's Ultimate Blast in those video games is the Dimension Sword Attack: he dashes at the enemy and proceeds to use the sword to slash them a few times, finishing the attack with a green mouth energy blast.
Called Rakshasa's Claw (羅刹爪, Rasetsu Tsume), the sword attack is one of Super Janemba's super attacks in Dragon Ball Z: Shin Budokai, Dragon Ball Z: Shin Budokai - Another Road, Dragon Ball Z: Infinite World, and Dragon Ball Heroes. A technique identical to the Budokai version is used by the Fu-Lum in the Dragonball Evolution video game.
