Games : How much damage can a shield/block that belongs to Ganondorf take?

In all Super Smash Bros Titles, players can block. When they block, the player gets a bubble (shield) around them that absorbs damage and even reflects some attacks. But, if a player holds it for too long, or takes too much damage, the shield will pop and they will be stunned for a considerable amount of time. What precentage of damage does it take for Ganon's shield to break?

I only care for the information on SSB4, but if you can provide the data for more of them, go ahead.
