Werkudara
Raden Bratasena was the second Pandava member, the son of King Pandu. Bratasena was also named Bima and Bayusuta or Betara Bayu's adopted sons. After he grew up he was named Wrekudara, enthroned at Jodipati, as king.
Bratasena never used soft language on anyone, even with God, he also used abusive language. During his life only once, he spoke soft (or manners), namely when he met with Dewa Ruci. A dwarf sized god, which he considers to be a true god. But even though the language is harsh, full of wisdom, He also never lies.
