These supreme Origin gods managed to give Legion a lot of big problems. The clones died several times, but they didn't stop. They were able to manage to escape several times by teleporting away, so they were not discouraged.
They didn't stop, and they continued to steal. But they had to stop when they finally hit a wall they couldn't bypass or overcome when a Supreme Origin god with a Supreme Law of Space came after them. Both Legion-1 and Legion-unity died in the hands of that supreme Origin god. They couldn't escape because she could seal and cut space.
Their winning streak came to an end, and they even had to go into hiding because the Supreme Origin god was actively looking for them.She planted a lock on them that she used to track them. The lock could only be removed through death, so they couldn't evade her no matter how far they ran until she killed them.
