One day I'll have to sit down and write a handy copypasta that will serve me well whenever I feel as if my brain has been sucked dry - like today.
-Gallade.
Frankly, he falls more into the 'pokemon you KNEW you'd like as soon as you encountered one' territory, so it is rather hard to ephasize and elaborate.
Let's limit this analysis to the following, then:
-during first generation I had to learn to appreciate future bros.
-Now, hundreds of pokemon later, there are designs which feel tailored to suit personal tastes from the get-go. This is the case here.
On the side note, I wish the overall quality of Gallade fanart was higher - no matter how long I search, only a scarce handful of good artworks resurfaces and next to none is on par with god-tier quality seen for mons from earlier gens.
