Not strictly relevant, but I once saw a build in this forum for a power that essentially gives the PC extra lives; I believe it was built as Regeneration (Resurrection only) with Charges, with a custom limitation "Player must provide an excuse for why the character is actually alive." The flavor being, of course, that the character heroically or luckily avoided death at the last second, ie the "My bible stopped the bullet" approach (or, alternatively, the "it was actually a robot that looked like me" approach).
If you just declare that every character has this power with, say, two charges that never recover, then you can kill each character three times before the player needs to make a new one. A bit more breathing room for making a lethal campaign, while your players don't need to worry about making multiple characters for a while.
