Velveno (ベルベノ Berubeno) is an escaped convict with a 2,000,000 Jewels bounty on his head, which has been increased to 4,000,000 Jewels by the year X791.
Velveno is mentioned briefly after Fairy Tail member Gray Fullbuster accepts a job request with a 2,000,000 Jewels reward for Team Natsu to capture him. However, they cancel the job after Lucy Heartfilia goes to rescue her father Jude from Naked Mummy.
