Sharkbeard is the leader of the Pirates in Gunpowder Island and is one of the main villains in the series.
He hates Ruby due to her being female, as females are considered as '' Bad luck '' in Pirate beliefs, and also due to her being the main reason for Ruben's retirement in Pirating. Which basically resulted in Rubens not being able to travel alongside him.
Sharkbeard is seen to be extremely self-centred, ill-tempered and greedy. Although despite this, he does have his rare moments where he shows mild care for others and does admit to his mistakes.
- In certain episodes, there is an animation error where Sharkbeard can be seen wearing his old hat which Ruby stole from him, for a split-second.

- Sharkbeard is seen to show a huge interest in poetry. As noticed in the episode titled Poetry Party.
