Bestovius is one of the ancients who wields the power to flip between dimensions and give that power to others. However, he can be quite egotistical and condescending, as many who have power do.

His voice should be medium-low to medium-high, and sound elderly, but not like he's on his death bed. His air of doubt towards Mario and overall a little bit snobby nature should be heard laced in his voice.
