Digimon: Penguinmon
Chicchimon rescued Bryan from the locked room when she somehow picked up on a text message Bryan sent from his phone. She is almost Bryan's polar opposite - she is emotional and totally at ease among others. Somewhat unusual for a penguin digimon, she has a fiery temper. But she is also very insightful and an excellent judge of character. Penguinmon is as social as Bryan is introverted.
Bryan, totally lost in his new surroundings, depends on Chicchimon more than she would like. She stays with Bryan because she gets bored very easily, and Bryan's appearance is something very unusual - and therefore interesting (for the moment). As long as Bryan's journey remains interesting, Penguinmon will stand by him.
While she was journeying with him, Chicchimon was knocked out by a rampaging SkullGreymon. Bryan cared for her while she was unconscious, and when she recovered, the bond between the two of them was a bit stronger than it had been before. Then later on, Bryan protected her when they fell out of the sky, keeping her safe at the cost of his own safety. Through their shared experiences along the way, Bryan and Chicchimon are becoming very close.
