Tifa Lockhart

Tifa puts up with a lot in Final Fantasy VII, running the bar, hosting Avalanche meetings, helping take care of Marlene, and even taking care of Cloud when hes suffering his massive breakdown partway through. Were still not sure where she falls in terms of the whole Cloud/Zack thing, but suffice to say shes a trooper the whole time. And unlike Aeris, she doesnt get herself killed before the first discs even over.
