Normal Zombie ---> General Zombie
Pacifista ---> Pacifista Mark III
Gifters ---> Headliners
Sea Beasts ---> Sea Kings
Shallow Knight ---> Deep Knight
You know what's common between these Man-Made Armies? They are Commanded by a Girl:
Zombies listen to Perona,
Pacifista listen to Bonney,
Smile Users listen to Tama,
Sea Kings listen to Shirahoshi,
Also, each Army have a Third Team who represents it's Best: (They also cannot be Commanded by those Girls)
Special Zombies represent Top Zombies,
Seraphim represent Top Pacifista,
Tobbi Roppo represent Top Headliners,
Gorosei represent Top Knights,
So what's Left?
This means that Shallow & Deep Marked Knights are gonna be Countered by Some Girl, and it's probably Pudding with her Third Eye,
And it also means that there is an Elite Group of Sea Monsters who are even above Sea Kings & cannot be Controlled by Poseidon,
Also, just like Hogback created Zombies & Caesar created Smile Users & Vegapunk created Pacifista,
It means that Imu is probably a Scientist, and there is another Scientist who created Sea Beasts/Kings, (Possibly Willie Gallon)
