Hi,

I wanted to report a bug that occurred to me a couple of times: sometimes my Beedril (who is level 12 and has only Fury Attack) will perform a "Struggle" move when i click on Fury Attack. I tried to understand why it happens to help you, but it seems that it happens in random circumstances. If the battle ends the move will return normal in the next one. Next time it'll happen i'll make some test to help you and i'll add them in this topic.

Now the problem is that beedrill learned a new move while i was testing, and i can't guarantee that the bug will persist.

It's not a bug. When a Pokemon runs out of PP for all of its moves*, it will start using the move "struggle" which is a 50 base power Normal type move (can hit Ghosts) and deals back 1/4 of the user's maximum hp in recoil.

 

So basically, your Beedrill runs out of Fury Attack PP, then starts using struggle.

*= or the move that it's locked into via Choice Items/AV etc.

Yup, if you run out of pp you can always use a leppa berry
