Eago the helper ghost

&nbsp Eago is rumoured to be the most powerful of the characters in B3T. Although certain rules of a helper ghost disallow him to show that power level. He is commonly seen beside Mokuba helping him catch shade demons or aiding him in combat. Very commonly he'll say "Eago at yo soivise!" Which is supposed to be "Eago at your servise" but thousands of years in the spirit realm seemingly messed with his vocabulary.
