Killer Robots?
That is a misnomer. The original name was 'Robot Killers'. Their mission was to seek out and destroy all robots and protect all living things. But somehow the name got mixed up and people called them 'Killer Robots' and they had to go into hiding because they were no capable of ever killing people. To this day no body believes this and they have to hide themselves from frenzied mobs.
It is very sad indeed that this site would also promote this ugly and false rumor and cause so much pain to such kind and sensitive silicon-based life-forms.
