Luka Blight taking all the arrows in Suikoden 2.
for me it would be lionheart, from ffviii, the ultimate action move from squall, i loved it and find it still today a nice animation, but seeing in nowadays visuals would be awesome...
This is the kind of thing Dissidia is good for.
That's Army of One, but close enough.
There were cinematic Limit Breaks in the first Dissidia fopr PSP. That one had Renzokuken, but the graphics weren't exactly a huge leap over PS1.
