Happy wasn't created form nothingness though, neither was Lucy, they didn't say that lead was created just the impact of Minerva's attack was heavy like lead (unless I was reading a crappy translation) and the whole creating heat thing does necessarily mean her powers are the similar. I honestly think both their powers are very different but we need to wait and see.
