The Droid Destroyer is one of the most dangerous and feard artifical beeings ever made. Originaly designed by the Colicoids   from Colla IV the Droidekas soon got the reputation of sharp aiming killers and lousy chess players. Their three leged   constuction makes them very slow in using their feet for movement, so they use a rolle method for fast getting into battle. This   makes them most vulnerable to their natural enemies: stairs.
