"With a friendly nature and a beautiful chirp, Fletchling is a popular Pokémon among many Trainers. But Fletchling is also known to be ferocious in battle, capable of unleashing relentless attacks!"
"Fletchling, a Normal- and Flying-type Pokémon, sings with a beautiful chirp that is sure to delight any Trainer. Although it is known to be very friendly, Fletchling will suddenly unleash relentless attacks once it’s in battle. For example, when it uses its Fire-type move Flame Charge in battle, in addition to doing damage, Fletchling’s Speed increases every time."
Damn. None of the other early birds got this kind of reputation. Taillow cries at night, Starly is loud and annoying, Hoothoot keeps time, Pidove can't even follow orders, and Fletchling is a ferocious and relentless killing machine. Interested to see which direction they take this little guy.
Also, Yayakoma and Dartiri, his Japanese and German names, also reference arrows ("ya" is Japanese for arrow and dart is the same in German as in English)
