Beartic, as well as it taking on all of those attacks in the episode it got caught by Iris. Not to mention that it also went toe-to-toe with a Hydreigon.
Blaziken, Gyarados and Mamoswine might all three be around the same level, but Dragonite is nearly in a completely different league. After all, it is a fully evolved Dragon-type.
If you ask me, Dawn went pretty much by raw strength in this battle against Dragonite, didn't she? So, no, I don't really follow you there. Besides, Dawn made it to the final round in Grand Festival, advancing through more Contest Battles than May, and as well did a better job than May. I really fail to see your point here, as Dawn could just be the most battle-active girl out there, so no.And im not sure how its bad excuse when its obvious how May and Misty are more familiar with real, trainer battles than Dawn was making it a given how their pokemon would be more focused on raw strength and strategy we see from trainers in general.
Ash didn't use a strategy. He took advantage of the battle when Dragonite went berserk, not listening to Iris anymore, thus being able to easily beat Dragonite. And Drayden, he's a Gym Leader, and he also went pretty much by raw strength as Mamoswine did in their battle, but Druddigon is too way too strong.We can see that when Ash and Drayden faced Iris and Dragonite using different strategy and combination of attacks than Dawn prior to that did, having higher success as result of that.
I watn you to take a look at the Sinnoh Grand Festival, the battle Dawn had with Ursula. Did you see all of those Shadow Balls that Mamoswine was hit by? And all of those other attacks too? He got hit by a LOT of them, and yet he managed to stand up. Gyarados and Blaziken will definitely not beat Mamoswine there, especially considering how little we've seen from the both of them. Besides, Blaziken almost lost to a Grass-type Pokémon, who Ash even received later than when May got her Torchic. And Gyarados? No, I've seen too little from him to even judge, but I'm guessing that he's about a regular Gyarados, just like the one Pikachu beat in the battle against Wake.Especially when taking in account their fighting abilities with Gyarados and Blaziken showing more strength and resistance in battles from what i saw than Mamoswine did. Something i counted in examples which were ignored.
