Grandpa Susan Acachalla

Grandpapa "Susan" Acachalla is the father of Papa Acachalla and the son of Grandfather.

Biography
Grandpapa lived in a house with and his maid, Maxwell (whom he didn't know about, and who removed Babychalla's left arm) and his son, who floated around the room

Personality
Grandpapa had a quick temper and little patience for Papa's tomfoolery. He shouted quite regularly, especially because he couldn't get him to say "This is Sparta". He showed little to no concern for Papa's safety, asking him to test his warrior abilities by jumping headfirst through a window and fighting an Allosaurus. However, he showed great pride when Babychalla reached his final form: Baby Tank.
