Ultimate Malleo

Ultimate Malleo is

Malleo's strongest form. He can not be harmed unless if he is in battle with Ultimate Weegee, or anyone who can harm Ultimate Weegee. He has an upgrade to this form if he uses a fire flower, but it's similar to the upgrade Ultimate Fire Weegee, Ultimate Fire Malleo is considered to be one of the most powerful forms of all time.

He also has all of Ultimate Weegee's abilities, but a little weaker.
