Sento

Sento was a Fire Glatorian and once fought Silver-Silver in an arena match on Bara Magna. He managed to land a few punches on Silver-Silver, and threw him into a wall, but was continually beaten and generally outskilled. Knowing he was beaten, he submitted to Silver-Silver, making him the winner. The match was watched by Nirtis, who then became interested in Silver-Silver.

Sento was presumably killed during the destruction of Bara Magna by Blackout, and revived when its destruction was reversed by Yon and The Architect.
