Frankly, Lolda just made Loki a more hated Chaotic Neutral Oden, especially after the last chapter.
Every arc has had a character(s) like this.
Loki, Seraphim, Oden, Judge, Kyros, Vergo, Vander Decken/Shirahoshi, etc
An outlier who is powerful and influential but not the main antagonist, essentially a wild card. One of Oda’s best and most risky storytelling devices.
