You have to fight shadow twice when you fight him the first time is not reallly all that tough dont worry about using your hyper modes and when his LE is down to a point he will use break armor that will
reduce his armor to 0 and you have to watch out for his energy charge if you do not interrupted the charge it will do heavy damage to you and when you do interrupted it, it will be a fragment cannon and to interrupted it just use axls wild jango and that should do the trick
Now for round 2 and Zero is in the party Zero will bump the character in the third slot out, now shadow is a little bit more powerful then the first fight his got 10,000 more LE a small boost in all stats but armor his armor is still 0 so there for you can just go all out
