The strength ranking of Agra Knies Zerg, Zeg Zerg (Alien) and Tyrone Zerg.

The Tyrone Zerg is the strongest. After all, it can destroy the Milky Way.

Heterozoa is the second, only in a certain area, there is also a spirit that can burn glass balls with technology.

Arazi was beaten 50-50 by humans who used gunpowder weapons (only from the perspective of movies, I haven't read the novel, and I heard that Angela Zerg in the novel is more powerful)
