Whats a good name for our new calf?

he is only 3 days old and already he's been thru a lot his mom is very sick and most likely we r gonna loose her, he's unable to feed off his mother so we r training him to bottle feed, but becuz of not eating well his weak but he is def a fighter! So I was thinkin of something along the lines of a name that means strong or a fighter, I just can't think of nething oh and its a male! Lol
