I drew this just for fun because why not. Note: not really sure how powerful Ghost, Amy and the rest of my characters are so take it with grain of salt.

Ghost and Amy are at a deserted island for vacation, amy was curious on how powerful Ghost is after seeing what he's capable off, she decides to ask him to lift her up as high as he can and he did, and then amy decides to grow into her Titan size out of curiosity, not a problem for ghost, guess he can lift something that ginormous.
