Chaos Ripper

Chaos Ripper (カオスリーパー) is a Keyblade that can be wielded by Terra in Kingdom Hearts Birth by Sleep. It has maximum reach and the highest strength boost of any Keyblade in the game, with the second-strongest Keyblade Void Gear giving a strength boost of eight. However, the Chaos Ripper is also the only Keyblade to lower magic, resulting in Terra's magic attacks being very weak.

Design
The Chaos Ripper bears a damaged sword-inspired design, with a hint of red and yellow and a blue eye seen at the end, shared with the Soul Eater, Way to the Dawn, Void Gear, and Master Xehanort's Keyblade. The teeth more closely resemble the Oathkeeper. The Keychain resembles a small demonic eye, though it is not the same used in Xehanort's Keyblade.
