[@Prostagma]it tanked a laser by deploying specifically anti beam measures from its wings (check the sheet), lost its shield and beam rifle and had its armor weakened because of the high energy. It survived, but not by much. 
Expecting to just one shot a player suit is ridiculous. and expecting it to just one shot after tunneling through the whole station ontop of being a stray shot is powergaming in itself.

I'm happy to play give and take in a fight and will lose when i've been outplayed, but simply throwing a stray satellite cannon that just so happened to hit kyo exact location, expecting it to just one shot the gunpla is not fair or ok.
