Beth Gilbert is the daughter of Billy Gilbert and Julie Makimoto. She is a Subterra brawler partnered with both Hammer Gorem and Cycloid. She is also a member of the Earth Division.
Beth is a 15 year old human girl. She has short, silver hair and blue eyes. She also has dark freckles underneath her eyes, along the bridge of her nose.
Beth is the most optimistic member of any division, and is probably the most optimistic character of the whole series. She is easily excited, and has tons of energy that she seemingly pulls out of nowhere. She tries not to let anything get her down, and even if it does, she can pick herself back up.
As good as Beth is at picking people up when they fall down, her optimism is sometimes unwanted and can get her into sticky situations with various other characters. She never means any harm though, and is a very innocent person, only wanting everyone to be happy and get along.
Even if she's not the best brawler around, she still has faith in herself and her abilities. She believes in both herself and others, and acts like a personal cheerleader when she is not the one battling.
