|My generation has to hold the zombie banner a little higher!|
— Mantha: Disarmed and dangerous.
Mantha the Zombie is a character first introduced in Casper's Scare School. She is a real zombie girl, and student that attends at Scare School and one of Casper's closest friends. She is one of the main protagonists in the Casper's Scare School and television series with the same name.
Mantha is a young zombie girl with purple eyes, blue hair and blue-green skin. Her regular outfit consists on a pink shirt with a white flower on it and a short faded black shirt underneath, tattered purple flare pants and black and pink sneakers.
Mantha is a strong and independent person, despite being a zombie. She is actually pretty smart and dislikes the ways zombies are portrayed in media: dumb and slow creatures that are unable to rationally think. This stereotype upsets Mantha to the point she wants to terminate this misconception. She also advocates for the equal treatment of all creatures in the Underworld and is usually willing to help others in the case that problems should arise. Mantha tends to be sarcastic, cynical, and refuses to accept help from others; however, she is a loyal friend.
Casper first met Mantha after being enrolled into Scare School, just after boarding the famous School Pirate ship, when Thatch made fun of her appearance. Matha defended her "zombie pride", soon she becomes close friends with Casper in the film, even helping him with his plan to sneak out of Scare School to visit the valley of shadows, even against Scare School's rules.
In the television series, she is still one of Casper's closest friends, always willing to help the Friendly Ghost in his adventures. Mantha is often underestimated for being a zombie by the rest of the classmates; however, she always manages to overcome her problems and prove her worth to the world, even sometimes surpassing Thatch who is the top student at Scare School.
Just like Ra, she is aware of Casper being friends with Jimmy, and is also friends with him, despite having human friends being forbidden by the rules of the underworld. However, she seems to enjoy scaring more than Casper and Ra, and she is not as friendly towards other humans.
