This scythe is a weapon that is able to shift into different forms that allow the user to use it in different ways every time it changes its form. It is also known as Akumu and not a literal weapon only when she is split in two.
Bete is well known for having a wide arsenal thanks to her weapons. Originally, she usually made Kumu transform into one of these weapons. But, once her soul was intact, she began to create these weapons by herself.
- Scythe: Possibly Bete's best-known weapon, (besides her iconic spear) which is mostly used weapon to attack her foes. Also, she can use it to destroy or throwback enemy projectiles (as shown in Do or Die).
- Dark Magical Explosions: HATE has the ability to enable this weapon to create explosions.
- Dark Magic Enhancement: HATE has the ability to amplify the weapon's attack damage releasing a black, smoke-like energy at the tip of the scythe.
- Scythe Slash: Bete Noire can also use an extremely powerful slash with her scythe. She can be seen using it multiple times in the series, including her battles with Gaster and Undyne the Undying.
- Hand Sythe: This is self-explanatory, as her hands become scythes, though, she can only use this if she is whole.
