Another Century's Episode/Headscratchers

• There's a fair bit of Fridge Logic involved, but the most outstanding issue creeps up in the third game, with the Gundam X and Double X being able to use their Satellite Cannons on "Earth A" despite the fact that version of the world lacks the external Applied Phlebotinum used to power it.
• Another bit from the third game, specifically the Chars Counterattack finale. Why is Axis even an issue, considering that by this point the protagenists have all the fire-power of the Wing Zero, the Double X and the Freedom? Especially confusing once you remember that stopping a Colony Drop was exactly what the Double X was built to do.
