Simile and mythological. The reason why is because a simile has like or as (acting "like" Hercules) and it talks about something that is a myth (Hercules.) It is not a metaphor since it has "like," it does have alliteration since it does have a repeated letter, it is not a hyperbole since it does not talk about anything so dramatic (instead, it was a simile,) it is not a literal language since it has simile and mythological.
Hope this helped!
