I just realized something. Before Zero came along, the Resistance fighters were more or less useless against Neo Arcadia. Why didn't Copy X just crush them when he had the chance? He clearly has ICBM-level weaponry, and his army easily tore through the soldiers in the opening cutscenes. Hell, the Big4 could've killed everyone in there by themselves.
The only reason that Copy-X wouldn't level the place would be Ciel's presence. Since he's refusing to kill a human, why not just drag her out before blowing the place up? Clearly, he knows where it is, because Hanumachine broke in fairly easily, and Hittide Hottide was airlifted directly there.
Thoughts on this?
