Do master balls ever fail?

Let’s make this more clear, shall we? Let’s use my good old friend called math.

It’s different for generation. I will do these calculations based on a Mewtwo with 100% health and no status ailments, with a Master Ball, whose rate is255x.

Generation 1’s Master Ball is automatically caught. There are no formulas using for a ball catch rate if a Master Ball is used. It bypasses the formula.

Generation 2 uses this formula:

a = (3 × HPmax - 2 × HPcurrent) × (rate × bonusball) / (3 × HPmax) + bonusstatus

Now, let’s plug in:

a = (3 x 416 - 2 x 416) x (3 x 255) / (3 x 416) + 0

Since 3 x 416 and 2 x 416 are both greater than 225, the value must be quartered. How perfect is it that 416 / 4 is a whole number :3

Since a is 255, the Pokemon is caught. No exceptions.

Generation 3 and 4 use this formula:

Let’s do some mathz.

a = [(3 x 416 - 2 x 416) x 3 x 255 / (3 x 416)] x 1a = [(1248 - 832) x 3 x 255 / (3 x 416)] x 1a = [416 x 3 x 255 / 1248] x 1a = [280800 /1248] x 1a = 255 x 1a = 255

Master Ball still catches.

Generation 5 follows the same formula as 3 and 4, but the bonusstatus is higher than Gen 3 and 4 for sleep and freeze. Even if you factored those in, the catch rate will be higher than 255, which warrants a catch.

Let’s get this straight, OK? Master Balls never fail, unless used on a trainer’s Pokemon.The chance of failing thing is not true. It’s about as true as a Creepypasta. No reputable source has ever said a Master Ball can fail.

They better not fail! >.< Just kidding! But, no. They never fail unless you try to get a trainers Pokemon ( if you use action replay it will let you catch trainer’s Pokemon so then it won’t fail) so don’t worry! I hope I helped! :D

The master ball bypasses any and all formulas for catch rate, so any chance of it failing from the formula is automatically null for the Gen I games. Everything else gives the master ball a catch rate of 255, the maximum they can possibly program, so it would be an automatic catch regardless of any other factors.

Thecatch rate formulais what determines the probability of any Pokemon being calculated. The actual formula varies by generation, so i’ll let you check my source if you’re interested.

The master ball is special in that the game runs a check specifically for master balls before even running the formula. if it is a master ball, then the catch will automatically work. no question. If it’s any other ball besides special ones (like the migration balls in Heart Gold, I don’t remember what they’re called), then the formula will run like normal and give your Pokemon some chance of being caught.

The only time a master ball can fail is if used on a trainer’s Pokemon or the Ghost in the Kanto games, but a special check is also ran on if the Pokemon is wild or not, so it’s not a product of the master ball.

of course, there isthis little thing…but going in just the games, it doesn’t fail.

Obligatory math shot of catch rate for everything else. Even if the master ball was put in the formula, it has no random values to generate for the formula, so the game would probably crash or something.:
