I want a summon to cast its ultimate attack and then disappear like in the old final fantasy games.

The problem is that the ultimate attacks of garuda, titan and ifrit are not as good as in old final fantasy games. They just do a raid-wide aoe instead of ifrit erupting out of the ground and dashing, arriving on a comet, titan raising earth up and that sort of thing.

What makes up for this is that after the summon disappears, the attacks the summoner does resemble these actions more, like earth erupting from the ground and ifrit's dash.

(I recall them clarifying that carbuncle can be made to look like any of them?)
