The sentences you provided are all grammatically correct and convey different ideas about what a champion can be in different contexts. However, it is important to note that the word "champion" is typically used to describe someone who excels in a particular area, such as sports or a specific skill. While some of the sentences capture this idea, others describe admirable qualities or actions that do not necessarily align with the traditional definition of a champion.
