Soma Peries

Soma Peries (ソーマ・ピーリス, Soma Pirisu?) is a fictional character in the Gundam series, Mobile Suit Gundam 00. At her first appearance, she pilots the MSJ-06 II-SP Tieren Taozi, but eventually abandons it for one of the semi-mass produced GNX-603T GN-X units. In the second season, she is one of the two known A-LAWS soldiers (the other being Mister Bushido) to be given a custom GNX-704T Ahead unit.

It is revealed later on in the series that she is in fact an alternate personality of the original Marie Parfacy.
