This scythe is a weapon that is able to shift into different forms that allows the user to use it in a different way each time it changes form. It is also Akumu, and not a literal weapon 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 (beside her iconic spear) which is mostly used weapon to attack her foes. Also, she can use it to destroy or throw back enemy projectiles (as shown in Do or Die).
- Scythe Slash: Bete Noire can also use a really 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, her hands become scythes, she can only use this if she is whole.
