Calling out a power or ability that a character can use but has only ever used once or twice and expecting them to use it in a normal fight is a little far fetched don't you think?I know that he wouldn't start off with full powered screams. However, I need you to realize that in his fight on the moon, he was just whispering.
It all depends on the villain he is fighting and how many times said villain has appeared. But just seeing it once lets us know that the character is both aware and capable of such.
Whispering where? At Hulk? Because it sure looked like a yell to me.
