Bola

Bola (ボーラ) is Klaymoor's brother and a veteran air-pirate. He is laid back and doesn't care too much about finding the Mother Lode as he is aged and has enough money to have a good live for a long time. He can float in the air and "teleport" anywhere. Mega Man must battle him twice in the Manda Ruins. He obtained the key before MegaMan, but lost it to one Reaverbot and MegaMan must defeat it to obtain the key. He also appears in the Nino Ruins to help Klaymoor when he had a back pain, and the two are last seen in Calinca with other pirates, where they decided to stop the search for the keys.

Trivia

 * His name probably comes from Bolas, a weapon made of weights on both ends of a rope, which is thrown and tangled around its target.
