Marrow Sucker

Marrow Sucker was the name of a Laistrygonian Giant that along with Skull Eater and Joe Bob was part of a group of giants that infiltrated Percy Jackson's school posing as visitors from Detroit. While undercover they joined a dodgeball game with Percy's new bully Matt Sloan during which they transformed to their true forms and attempted to kill him using flaming dodgeballs. Marrow Sucker participated in this battle and is known to have perished in it as well being sent to Tartarus.

Noteworthy:

Of the three named Laistrygonian Giants Marrow Sucker is the one that we know the least about. His name is given only a few times in the chapter and though it is clear he fought in the battle and was defeated in it, the author did not write exactly how Marrow Sucker was sent to Tartarus, as he did for Joe Bob and Skull Eater. Since the only other mentions of giants disintegrating in the book are of Tyson redirecting flaming dodgeballs back at them it can only be assumed that this is how Marrow Sucker met his end, which would make him the first of the named giants to be defeated in the fight.
