This has bothered me for years, so I'm apealing ot the collective wisdom of the EoFF community.
In the Chrono Cross Opening FMV there is a clip where Serge levels his swallow (presumably at an enemy of screen) and charges forward, in what looke like Termina. Despite playing the games multiple times I have never seen this in game and have always been wondering where it is from.
