Wake

General Info - Wake, or "Crasher Wake" has an arsenal of hard hitting water types at his disposal. Both Gyarodos and Flotzel have very high attack. If you have battled a trainer, (You probably have) you may have lost a pokemon to this beast (I know I have :P). If you have raised a Floatzel, you also know how fast and strong it is. The best strategy for this battle is to come in with some bulky Pokemon that are ristant to the Water type and can pose a threat (Grotle, anyone?).

Lv 27 (Water/Flying) - I hate being on the wrong end of a Gyarados. You should too. I have no idea how this thing gets off the Ground, but it does, and thus it has a ristance to grass. But this is also somewhat of a double-edged sword as Gyarados is 4x weak to Electicity. If you have an electric type, this will be easy to bring down. If not, then Rock type attacks will do some damgage, but that's about it.

Lv27 (Water/Ground) - This thing isn't nearly as hard to take down as Gyarados was, because although it may be immune to Electric attacks, it has a 4x weakness to Grass, and Grass is a pretty common type at this stage of the game.

Lv30 (Water) - Floatzel isn't that powerful, at least not compared to the other Pokemon on Wake's team. It is a pure water type, so it is week to both Grass and Electric attacks. Floatzel attacks mainly with physical attacks, but Grotle may not be as excellent a choice as it may seem due to Ice Fang.
