506-δ was a robot made by Jake Gray to hunt down any rogue aliens and robots. She has to go through training and managed to become strong enough to hunt down rogue aliens and robots. Then when Jake Gray sent 506-δ, there was a strange-looking aquamarine. When she touched it, she got upgraded by that aquamarine. Then she managed to destroy any rogue aliens and robots in a second. But the main heroes (The most Popular Characters in this stream) can’t be defeated by her.
