| Description: Shin Beruwan Baou Zakeruga is Zatch's fourteenth spell. It is thi third and final spell where Zatch doesn't lose consciousness (the first being Rauzaruku and the second being Baou Kurou Disugurugu) An enhanced version of Baou Zakeruga, it summons an impossibly humongous, vaguely humanoid dragon made of lightning with many horns, a massive head on its chest similar to that of Baou Zakeruga, many massive wings, arms ending with claws similar to Baou Kurou Disugurugu, and a very long serpentine body, to attack the opponent. Cast using The Golden Spellbook and infused with the power of every Mamodo in existence apart from Clear Note, this spell is easily Zatch's most powerful; while a Shin-class spell in name, its power is in a league entirely of its own.
Due to how many stated that Baou Zakeruga was King Bell's most powerful spell, this can be seen that Shin Beruwan Baou Zakeruga is a spell that Zatch created himself from the energy of every Mamodo. However, due to how much power it requires to use, this spell cannot be used by Zatch himself.
