I find this to be among the saddest episodes of Batman Beyond's first season, because so many people face a tragic end without even asking for it in the first place.
The titular heroes in this episode were accidentally made what they due to being exposed to dangerous amounts of radiation. Their DNA eventually mutates and make them dangerous to everyone around them and they end up being chased by the army to be eliminated.
Yes, they discover about their worsening conditions and try to take down the one responsible person, but end up being defeated by Batman maybe without any hope of getting any help. The episode ends on a very bleak note, indeed.
