Meaning of 621

[Anubis]

Hi,
I wanted to say loving it so far, never played Armored Core before but I have played mech games in past .
The reason for this post is anyone really know what 621 means?
"e621"

9Ball

He was the first crazy hard AI boss of the original and has had many reincarnations in the series. It's probably a reference to him, Not sure if it's an intentional easter egg or something more lore serious though.

For an in-universe answer, it's probably just because he had 620 predecessors (at least the last couple ones under the same handler).

The number of genders in that current year.

In Japanese there is always a certain way to turn the words into numbers
621=浪人(rounin)="Ronin" in English, it means a wandering samurai who had no lord or master.

Yeah, the computer called you C4-621 when you wake up after the big explosion at the watchtower.

That's definitely a serial number, 4th generation, 621st candidate.

6 + 2 +1 = 9, and the handler said to wake up the dog. And what do dogs like fetching? Balls. Boom, there you have 9 ball, and he was created as an AI to control the world, Illuminati.
