The All SID vs Vagan Gear scene i have been thinking . wen SID connects to Vagan Gear it glows red , and then it starts to glow green ( same color wen an x-rounder uses its power) .
So could it possible be that SID tried to take over Vagan Gear and it failed due to its pilot's power? and that interaction caused him to run wild ?
Also look what decided to make a cameo ( those who saw first gen will see what i am talking about , its not in red but :
