Sulfur Pot is a member of the Acceleration Research Society and a Burst Linker Black Lotus meets during her trip in Okinawa.
Sulfur Pot is very cocky and confident in his skills. He is especially like this when he has his pet, Nick with him as he states that he is invincible. He treats Nick as a tamed monster pet and can confidently command him to do his bidding. However, this becomes his downfall as he is betrayed by the same monster that he thought of as his pet.
Kuroyukihime is reunited with Crimson Kingbolt, also known as "Crikin", a Burst Linker who moved from Tokyo to Okinawa after his parents divorced. Just then, they are surprised by the mysterious threat, revealed to be a Burst Linker named Sulfur Pot, who has the power to tame "enemies". When it is mentioned that Sulfur Pot doesn't appear on the challenge list, Kuroyukihime realizes that he's from Tokyo, using a backdoor program to dive into Okinawa. As they fight, later Orchid Oracle, changes the landscape to an ocean, giving Kuroyukihime and her allies an advantage against Sulfur Pot. After severing control of his mount, the enemy then devours him.
Sulfer Pot is a humanoid avatar with many holes on his body. His primary color is metallic yellow. He has blue eyes which are surrounded by a orange visor.
Much of Sulfer Pot's battle potential is focused on gas attacks. He has the ability to shoot out a dark brown gas at opponents. This gas, as pointed out by Black Lotus, is actually gunpowder. So when an ally (like Nick) uses a fire type attack, the gas will ignite and coat the entire area where the gas was in flames. He also has the Enhanced Armament, Mystical Reins that allows him to tame any monster which in this case was the legendary monste,rNidhogg.
