SPOILER ALERT: Here might be uncovered spoilers. Read at your own risk.
- The Radams' true forms are revealed to be parasitic worms. Their ultimate goal is to turn every man, woman and child on Earth into a Tekkaperson and possess their bodies. Extrapolating from this, it's entirely possible that those monsters Blade happily slices his way through in every episode are actually innocent victims of the Radam from previous planets they conquered.
- However given the fact that they likely are conquered and borderline driven insane by the Radams they likely would consider this a Mercy Kill rather then just the actions of a selfish new Radam host.
