Baou Kurou Disugurugu is Zatch Bell's tenth spell, and his second Baou spell.
Baou Kurou Disugurugu takes the form of an immense dragon arm. The Baou dragon's hand, with the Bell's electricity seal in the center of the palm. It is the second and last spell Zatch learns where he doesn't lose his consciousness , and it can be freely controlled by Zatch's own right hand. It is likely more powerful than Baou Zakeruga was before. Being a Baou spell, it is probably also one of Zatch's only spells that Zeno does not have.
