Arthor is the Gym Leader of Taurondo City's Gym, known officially as the Taurondo Gym. He specializes in Bug-type Pokémon. He gives the Antenna Badge to Trainers who defeat him.
Before battle- "FWOOSH!! Ah, so you made it all the way here to me. I suppose you earned yourself the right to battle me. My name is Arthor, the leader of this Gym and Bug-type specialist. Don't think you can win this battle by merely throwing flames or stones at us. Let us begin."
First non-KO hit- "Not bad for a first move."
Final Pokemon- "It is time to end this."
Final Pokemon in yellow zone- "Things aren't looking good."
After being defeated- "It seems my tactics were not enough."
After defeat- "Impressive. You have bested my strongest tactics. Here, take this. <player> received the Antenna Badge! That badge is a symbol of your victory here today. Now you get to use Surf outside of battle. Here, a token from me. <player> received TM28! That TM contains a move called Leech Life. It drains your enemy’s power to heal itself. A fiendish move, is it not? I shall return to training now, may our paths cross again in the future."
