021: The Uninvited Guest:

1) I've been wanting to add Susanowo to the storyline for a while now (spelled Susanoo here. This is not a mistake on my end).
2) For those of you who thought Sakigake had the Graham Aker AI, you're quite mistaken.
3) My original plan for Susanowo was to introduce him as an Overflag, have him upgrade to Sakigake's body after the latter was defeated, and THEN upgrade to Susanowo before the battle with Neo Zeon's head honchos. I think what I went with will work better.
