Marivel (or Mariabelle in Japan) is a Crimson Noble (in Japan, ノーブルレッド "Noble Red") - a near-immortal vampire - in Wild Arms 2. She is friends with Anastasia Valeria, but is otherwise too scared to make friends because she outlives them. Marivel is a technological genius, controlling two robotic familiars named Hob and Nob, using the golem Quebley in battle, and fixing Kanon's cybernetics. Marivel can join the party as an optional character; while not needed for the story, her tools help unlock various extras that can't be accessed otherwise, including most of the optional boss battles.
While Mirabelle Graceland's name and Crimson Noble race are the same as Marivel's, they are not the same character.
Marivel also makes cameo appearances in Wild Arms 3 (not in person, but as a character in a serialized childrens' story that's found in books throughout the game) and 5. Humorously, her cameo in 5 is that of a black market dealer who sucks the characters' levels in exchange for rare items, living up to her vampiric origins. Marivel is also well known for being a terrible singer; she's so bad, she attracts monsters.
