I think my problems with Axew's strength comes from it's weakness being empathized too much early on. So Axew is not able to with stand a 20% bullet seed but then suddenly it is able to learn the most powerful physical dragon move and beat a Gollet. They should have Axew learn a weaker different move. It was early on so it wouldn't be hard for them to catch up but the point aaaat which they caught up felt a little to late to be possible. They should had them catch up a bit earlier but with weaker moves start them off with bite. And instead of beating other trainers how bout wild pokemon. But then again the anime has never been the best at move time placement.
