Death Medarot
From Medapedia
 
Death Medarots, (Known as Kilobots in the english dub) were a type of medabots that only appeared in the anime. In the games, there was no difference between death medarots and normal medarots.
Overview
Death Medarots are shown to be much more powerful than standard medarots, they also use Death Medals (ExMedals in english dub) in place of standard ones. These medals made them act on any order and didn't give any emotion to the Medabot.
A medafighter using a death medarot, or a normal medarot equipped with a death medal, was refered to as a "Rouge Medafighter".
