Byron (Japanese: トウガン Tougan) is the Gym Leader of Canalave City's Gym, known officially as the Canalave Gym. He hands out the Mine Badge to Trainers who defeat him. He specializes in Steel-type Pokémon. He is Roark's father.

In the games

Byron uses Steel-type Pokémon in his battles. Trainers who defeat him will receive the Mine Badge, TM91 (Flash Cannon), and will be able to use Strength outside of battle. Byron asked Riley to become a Gym Leader, but Riley declined because he thought Byron's son Roark should be considered first. Byron isn't surprised to find that his inexperienced son lost to the protagonist, but is enthusiastic about the next generation of Pokémon Trainers. Byron resolves to train harder at Iron Island to compete with younger Trainers.

He apparently owns the normally deserted cabin on Iron Island. After the Elite Four, he can be found there. Speaking to him results in him chiding himself for still treating Roark like a child; he will then give the player a Metal Coat and leave. In Platinum, he mentions that he lived on Iron Island for a long time and so feels out of place when visiting the Villa. Along with those visits, he can also be battled again at the Battleground in Platinum. He also battles the player in Pokémon Black 2 and White 2 in Pokémon World Tournament.

Canalave Gym
  • Before battle
"Ah! That's Oreburgh's Gym Badge! I see, I see! You've defeated my son. But that's no surprise. He still has much to learn. In place of my son Roark, I, Byron, will take your challenge!"
  • After the opponent sends out their last Pokémon
"Oh, what's this? My last one! This is where we make our stand!"
  • When the opponent's last Pokémon is at critical health
"We're not done yet! There's no giving up!"
  • Upon being defeated
"Hmm! My sturdy Pokémon, defeated!"
  • After being defeated
"You were strong enough to take down my prized team of Pokémon. In recognition of that power, I give you this: the Mine Badge!"
"Having the Mine Badge enables you to use the hidden move Strength anytime outside of battle. And you now have six Gym Badges. That means all Pokémon up to Lv. 70 will obey you with question. Here! Take this, too!"
"That TM91 contains the move Flash Cannon. If it hits, it may also lower the target's Special Defense."
  • If talked to again
"Gwahahahaha! The Sinnoh region is vast! Tough Trainers like you and <rival> crop up constantly to challenge the old guard! With more young Trainers like my son and you two taking charge, the future of Pokémon is bright! But I'm not stepping aside just yet! I merely need to rededicate myself to training on Iron Island."
Resort AreaPt
"Guhahahaha! How's your Villa? Can you give me a tour?"
Yes: "All right! Let's have a look, then!"
No: "Well! How cold can you be?"
  • Any of the following
"Gwahahahaha! I spent a long time living on Iron Island. A place this fancy, I feel a little out of place. Don't get me wrong, it's a great place. It's nothing like my son's!"
"Well... I have to admit I'm not very interested in furniture and the like. My interests run more to things like digging tools, obviously. The shapes of Pokémon fangs and claws are interesting, too."
"Digging underneath Iron Island was a good time in my life. Working alongside Pokémon constantly for iron ore... But that's all in the past. The young people today should find their own paths to happiness."
"Roark is still a boy, but at the same time, he's a man in his own right. That's why our opinions clash at times, and why we break out in battle. Gwahahaha! You weren't supposed to hear that! Forget I said it!"
"You're acquainted with a fellow named Riley, aren't you? He's a mystifying sort, that one. I have no idea how old he is, to tell you the truth."

Scenario 1

  • Before battle
"I've faced many a challenger at my Gym. I trained on Iron Island while contemplating my worth for days... I have the confidence now to batter down your defenses. Could I ask you for a rematch?"
Yes: "We are tempered and honed by battling the strong. Here's to our showdown!"
No: "When you came to my Gym, you had a glint that's dulled now."
If talked to again after the player answered "No": "I have the confidence now to batter down your defenses. Could I ask you for a rematch?"
  • When the opponent's last Pokémon is at critical health
"We're not done yet! There's no giving up!"
  • Upon being defeated
"Hmm! My sturdy Pokémon--defeated!"
  • After being defeated
"I trained by pummeling steel continuously on Iron Island alongside Pokémon... Gwahahahaha! I could still use more toughening up!"

Scenario 2

  • Before battle
"Since we last lost to you, we've been in training. I think we've addressed our shortcomings. Could I ask you for another rematch?"
Yes: "Thank you! Like me, my Pokémon were longing for another chance to battle with you!"
No: "Gwahahaha! That's disappointing, but all right! There's a lot to be learned by battling you. We had our hopes up."
If talked to again after the player answered "No": "Could I ask you for another rematch?"
  • When the opponent's last Pokémon is at critical health
"We're not done yet! There's no giving up!"
  • Upon being defeated
"Hmm! My sturdy Pokémon--defeated!"
  • After being defeated
"Argh... Came up short again... Do I talk to my son Roark to train together...? No, that's too embarrassing... Hmm... This is a dilemma..."

Pokémon Black 2 and White 2

Pokémon World Tournament
  • Before battle (first round)
"I, Byron, will take your challenge!"
  • Before battle (second round)
"Young Trainer! I'm Byron. As a wall for young people, I'll take your challenge!"
  • Before battle (final round)
"Trainer! You're young, just like my son, Roark. With more young Trainers taking charge, the future of Pokémon is bright! So, as a wall for young people, I'll take your challenge!"
  • Upon being defeated
"Hmm! My sturdy Pokémon--defeated!"
  • If the player is defeated
"Gwahahaha! How were my sturdy Pokémon?!"
  • After battle (if the player won)
"Gwahahaha! You were strong enough to take down my prized team of Pokémon. I recognize your power. Please show your power to other Trainers, too!"
  • After battle (if the player lost)
"Gwahahaha! I happened to win this time, but we were under so much pressure, right? You've lost. Of course, you'll challenge me again, right? I look forward to it!"
  • In the lobby (after the tournament)
"Guhahahaha! I lost, but I saw something great. Well, guess I'll go back to Sinnoh and start my son's training over! All right! Next time I take part in the tournament, I'll play to win!"

In the anime

Byron in the anime

Byron made his debut appearance in Ancient Family Matters! together with his son, Roark. It was revealed Byron had once been the Gym Leader of Oreburgh and had left his family to become the Gym Leader of Canalave as he was more interested in Fossils, leaving his former position to Roark. Byron battles his son for a short time before the match got interrupted by Team Rocket. It was later revealed that Byron still cared for his son as he kept the Fossil Roark had found as a child with him ever since.

Byron is obsessed with digging and Fossils. When his Fossils were stolen by Team Rocket in Ancient Family Matters!, Byron was too busy admiring the hole they dug into the building to notice.

In Dealing With Defensive Types!, Ash had his Gym battle against Byron, defeating him and earning a Mine Badge.

In Double-Time Battle Training!, Byron was presumably defeated by Paul, earning him his eighth Badge, and thereby making him eligible for the Sinnoh League.

Byron reappeared in a flashback in DP120, and also made a cameo appearance in the ending credits of Zoroark: Master of Illusions.

Byron and his Bronzong with Fantina and her Mismagius

Byron first appears at Canalave City talking to Roark over the Pokégear about his recent loss in a Gym battle. He then changes the subject to something that is later revealed to be about Team Galactic. Later, at the Canalave Gym, Byron wakes up to find Diamond, Pearl, and Platinum sneaking into his Gym. Acting on his impulsive nature, Byron attacks the intruders under the impression that they are villains. Believing Byron to be the person that caused her father and Professor Rowan to go missing, Platinum faces the Gym Leader in battle.

While they battle, a stray attack causes a curtain to be destroyed and reveals Professor Berlitz and Professor Rowan trapped in a cage. After being accused of kidnapping them, Byron reveals that he has been investigating Team Galactic for months and found a Galactic Grunt attacking and trapping the two scientists in a cage.

The next day, Byron hands Platinum the Mine Badge for his previous defeat and is tasked with protecting Professor Rowan and Professor Berlitz while they recuperate after escaping the cage. When Platinum and Pearl go to protect the three lakes from Team Galactic, Byron sends Diamond to go train on Iron Island with his friend, Riley, to increase his battling skills.

Later, after a defeat at the hands of Jupiter, Candice calls Byron and demands that he send her, Maylene, and Platinum someone to train them. After briefly considering Roark, Byron reluctantly calls up Volkner to help them.

Byron later joins the other Gym Leaders at the Spear Pillar with the Underground Man, Professor Berlitz, and Professor Rowan to help them fight Team Galactic. By using their digging skills, the Underground man and Byron heal any injured Pokémon by taking them from the battle and putting them back after using a Potion.

After Cyrus's defeat, Byron steals a machine from Team Galactic scientist Charon. Unfortunately, Charon's machine causes a disturbance in the hole in the sky that was created by Dialga and Palkia's fighting and mysterious tentacles shoot from the hole and pulls Cyrus, Palkia, and Dialga inside of it.
