How many water types get Bulk Up? If you want to use the canon/flavor arguement then go ahead, just know that because this is a competitive project, and isn't sponsored by Nintendo, we have ultimate jurisdiction on whether we choose to follow the canon or not. This is our project, not Nintendo's. If we say that it would be broken to give it Bulk Up, then we won't give it Bulk Up. We don't need justification. We can do whatever we want, most times we choose to stay within the canon to appeal to more people, or because it makes sense. However, if at any moment we as a community decide to deviate from the canon (which is what this whole project is doing), we can. I know this opens up a slippery slope of sorts, because then "We're doing whatever we want, we should make Garchomp 2.0 and fuck stuff up" comes up. However, we have another, more important limitation, and that is arriving at a (pretty) balanced metagame after every new Pokemon is added and a grace period of a couple weeks. Deviating from the canon, if to satisfy that second requirement, is fine in my eyes. If we want to deviate from the canon "just because", I am firmly against it. Think of it as two laws, but one can be broken in "self defense" of the metagame.
