Catch Power (Terramon)

A Poke Ball's catch power defines how likely it is to successfully catch a Pokemon.

This can be used alongside a Pokemon's capture rate to calculate the approximate amount of tries it will take to catch a given Pokemon.

The catch power for each Poke Ball is as follows:

Poke Ball	Catch Power	Condition
Poke Ball	1x	None
Premier Ball	1x	None
Great Ball	1.5x	None
Ultra Ball	2x	None
Master Ball	Always Successful	None

Calculation

The amount of tries taken to catch a Pokemon can be calculated using the Poke Ball's catch power and the desired Pokemon's capture rate.

To get the basic catch chance we can do ((capture rate / 255) * 0.85. For example, if Beedrill has a capture rate of 45 we will have a 15% chance to catch it every time we throw a Poke Ball (as the equation gave us 0.15).

This is only the chance for regular Poke Balls, however. To get it for another variant, we must multiply our basic catch chance by the Poke Ball's catch power. For example, we will be twice as likely to catch Beedrill with an Ultra Ball (which has a catch power of 2x) at 30%.

We can now calculate how many Poke Balls (or in this case Ultra Balls) we will need to buy in order to catch Beedrill. All we need to do now is to divide 1 by our catch chance, which tells us that we will need on average 3 Ultra Balls to catch our Beedrill.

Note that this amount is an average and won't be perfectly accurate.
