✔ The Purpose (Axel)
When we found Axel, they were amnesiac, and upon learning more, their kind, the Plasmoid are a kind of enslaved and created species, with a particular purpose in mind. The fact that they seem to have a free will and no idea what they're supposed to do is considered as an anomaly.
But they're wrong in my opinion.
After many adventures and a death, Axel seemed to have find his purpose, to free his kin and all the oppressed people by Astralcom.
