- Bug being super effective against Dark
- Fire resisting Fairy
- Fairy being immune to Dragon
This never made any sense to me, either. I get why Bug would RESIST Dark... but I don't get why it's super-effective. Feels a tad backwards.
The only thing I can think on this is fire burning up the magic, like... corrupting it in a sense. But... yeah, I don't really get it. lol
IMMUNITY I don't get... but I get resistance. In some lore dragons are basically HELPLESS against magic, and Fairy-type is really more of the Magic/Mystic type. With the lore they seem to be going with it adds up.
The biggest one, to me, is Ice not resisting Electric.
The only thing I can think is because electricity puts off a lot of heat, but... that's kind of splitting hairs.
By far the type effectiveness that makes the least sense to me is Rock being weak against Water. Why on Earth would a rock be harmed by getting wet??
The grand canyon is a perfect example of why. Over time, water erodes and weakens rock. It's why you find a lot of riverbed stones and other aquatic rocks that are very smooth and round. Since the type effectivenesses aren't always intended to be super literal (two birds with one stone explaining Flying weak to Rock) it actually has a lot more logic and science behind it than most. The same could be said about Fire being super effective to Steel. Most Fire types have Pokedex entries saying they're capable of absurd levels of heat, so it makes sense that they'd be able to melt, or at least weaken, steel very easily.
The whole Fairy being super effective against Dragon types never made sense to me.
In many forms of lore and mythology dragons are very vulnerable to magic... in these cases it's the ONLY thing that can harm them. Fairy is basically the Magic/Mystic type, so it makes sense. The irony with this is that it's also common in lore for dragons to be IMMUNE to magic as they are eternal masters of the ancient world, and only modern things like steel weapons are able to hurt them. But since Dragon was never weak to Steel, it's obvious this isn't the way they're going, and instead they seem to be going the "Dragons are druidic beings immune to the most primal of elements" route.
