When you think of cowards you think of selfish guys that only think about their safety first before anyone else's during trouble, some even go as far as use their collegues as decoys so that they can escape , they are often weak,easily intimidated and timid.
Example would be Usopp from One Piece & Kenichi from Kenichi:The Mightiest Disciple
