Zrone

Zrone is an intelligent, wasp like creature, from another dimension. He currently resides on Earth, somewhere on Mount Paozu.

Bio
Zrone originated from a dimension which was conquered by Carnus. Zarchnid, another member of Zrone's race, had betrayed Zrone and his people, and killed Zrone's family. After Zrone's dimension was conquered, he and others were enslaved by Carnus and Masidai.

The Return of Carnus arc
Zrone saved Knox, Lilith, Kuro, Nacule, and Hikari Minato whenever they were trapped in Zarchnid's web. Zarchnid had been enhanced and was stronger. Zrone fought and killed Zarchnid, avenging his family.

Zrone later helped them fight Masidai and, after defeated Carnus, went to Earth with the others.
