Diol Twee

Diol Twee is one of the heroes in Otomedius, the spin-off series of Gradius series. She is the third year student, the closest to being an adult in the cast and the Angel Squadron's leader. Although firm, she has a sisterly kindness to her approach on leadership. Diol seems to be bonded to the Flint, an organic component of her otherwise artificial Serenity Viper.

In Otomedius Excellent, Diol is an intermediate-level character. Her three Flint units are the new form of the previous Lock Options from Otomedius Gorgeous. They behave like normal options when not shooting, and lock into place when you shoot. Her Platonic Break fires out three very large flint tentacles like Xexex's Flintlock.
