Shiranui had found and caught a Fletchling with the Gale Wings ability, which he named Honoh.  "[i]Fletchling, the Tiny Robin Pokémon.  These friendly Pokémon send signals to one another with beautiful chirps and tail-feather movements.[/i]"

He returned to the gym and it was his turn to fight.  He listened to the most important parts of the official's statement, having won 16 badges already and the fight was on with Viola sending Surskit out.  "Honoh, I choose you!"  Shiranui sent out his Fletchling and the battle was on.
"Surskit, Bubble!"
"Honoh, Peck!"  The Fletchling put his Gale Wings ability to work and gave Surskit a swift peck.  The hit was critical and Surskit was knocked out.

"Impressive, Shiranui," Viola commented, "Let's see how you go with my Vivillon.  Come on out!"  Shiranui kept Honoh out.  "Vivillon, Sleep Powder!"
"Honoh, Peck!"  Vivillon was swiftly pecked thanks to the speed boost from Honoh's ability.  It released a cloud of sparkling powder that Honoh dodged.
"Vivillon, Gust!"
"Honoh, give it another Peck!"  The Fletchling flitted out of sight and pecked Vivillon from behind.  Vivillon flapped its colourful wings rapidly and buffeted Honoh with a strong wind.
"Vivillon, Gust again!"
"Honoh, finish it with Peck!"  Honoh came in from above and gave Vivillon one final peck before the technicolor-winged bug was knocked out.

"Shiranui, for defeating me in battle, I award you the Bug Badge," said Viola.
"Thanks Viola," replied Shiranui as he accepted the badge.  He realised Honoh would be very formidable once the Fletchling reached his final form.
