Banaro Island

Banaro Island is an island that was ransacked by Blackbeard and his crew. The island is very close to Water 7, but is not part of the Sea Train route.

History
Portgas D. Ace eventually finds Blackbeard, where a huge fight soon ensues. Before they began fighting, the citizens evacuate to the outskirts of the island and can only watch as their town is destroyed. Blackbeard shows Ace the powers he was given by the Yami Yami no Mi. The island is where Ace was defeated, and then soon handed over to the Marines. The island was most likely destroyed as a result of the battle, which would be known as the Banaro Incident.

Banana Rock
This island is known to have huge rocks that face up in different directions called Banana Rock. It was situated near the town where the Ace vs. Blackbeard fight occurred. It was destroyed during the fight.
