"Bannex is a mystery wrapped in more Bannex"
Bannex was a secret project on kamino called project Darkside, the project was a almost complete untill Ventress stole him, After the mission, Ventress was told to wait on plannet T'nab where she would leave him to grow in skill.A year later they meet again only this time Bannex is ready. After helping Echo get off T'nab he said he would only stay till Ventress had died! Soon after the Battle of Boz Pity, Bannex's fighting days were over, he left in his ship without looking back at his friends, after that he was never seen again...
Bannex is good at tons of thing like...
Sniping out enemys
fixing up ships
locating things using the sound of footsteps
jumping from unbelievable high thing (and living)
Can tell you the name of a planet just by looking at it
and telling jokes...
