Life = how much health the character has, defaulting to 1000.

Power = how many 'stocks' or 'bars' the character can have in their power gauge, divided by 1000; this means that the default value of 3000 gives the character 3 stocks/bars.

Attack = globally modifies the damage multiplier for the character's attacks, divided by 100; this means the default value of 100 multiplies damage by 1 (no change), whereas a value of 200 would double the amount of damage the character's attacks do, and a value of 50 would reduce the overall damage by half.

Defence = modifies the amount of damage dealt to the character, divided by 100. It functions the same way as the Attack stat, only it affects the amount of damage attacks do to the character, so a value of 200 would double the character's Defence and thus halve the amount of damage the opponent's attacks do to them.
