Marine is the first human to fall into the Underground after the fallen human. She is currently exploring the underground with Flowey the Flower. She considers him a friend, but he can be a little mean to her. She is the SOUL of Patience. She is afraid of skeletons. She is very trusting, almost gullible, but she wants to see the best in people. She always wants to do the right thing. She is in no hurry to get out of the Underground; she is willing to wait if she needs to. She is 11 years old.
