I find it amusing that you mentioned Liquid Flame without pointing out (or perhaps realizing) that it first appeared as a boss in FFV. Other characters that have appeared in multiple FF's springing right to mind are Gilgamesh (FFV and FFIX) and Gogo (FFV and FFVI), not to mention all of the summons/espers/eidolons/primals/etc. that are a staple of the series and appear in practically every FF game from FFIV onwards. It's what connects the FF series and makes us smile.

Music "re-use" is also common. In the FF series, certain tunes like the Prelude and Prologue (now Main Theme) appear in most of the games. Other times, snippets of songs serve as inspiration for others (check out Relm's Theme from FFVI and then "Eyes on Me" from FFVIII). That happens outside gaming, too. Check out Hans Zimmer basing the main theme for Pirates of the Caribbean off of part of his Gladiator soundtrack.

In all, having some reused assets is in no way whatsoever mutually exclusive with also having "brand new" content.
