Bucchi

ブッチ

Bucchi, a mad scientist residing in the town of Gloria, is frequently shunned by the other townspeople due to his reclusive nature. He builds armor to exact revenge on the town for their unfair treatment of him and their discrimination against his work. He is defeated by the Eldora Five (with a little help from Van) and is given a chance to mend his ways.
To atone for his past misdeeds, he upgrades the El Dorado with new technologies, such as the Bucchi Engine, much to Nero's chagrin. The Eldora Five do not take Bucchi along when they join with Van, a decision Jose believes was a mistake; he constantly reminds Nero of this fact whenever they encounter issues with their armor's maintenance. However, Bucchi does transmit data to assist Joshua with his calculations, in order to send Van into space.
