Although he looks like Leo Altman, he looks like his father because he is his father after all. The difference between Leo and Arrus is that Leo was very weak at first, but gradually became stronger with the help of Severn. Later, he became a master of cosmic boxing, master Cerro, the son of Severn Altman, and the fighting king of Showa Altman.
It can be seen that Arrus Altman is different from the old version and other versions of Altman as a whole. His painting style, appearance, origin and expression are very different.
