FFVI Worlds Collide

Actually, Possess is the most broken command even. It can instantly kill anything, including bosses and the final boss. The user would reappear on the airship after being forcefully removed from the party after using Possess. Hence the reason why the ghost characters are unlimited. They are just kick out of the current/active party and need to be place back into the party manually.

I would rather see the Morph command stay true to Final Fantasy VI, being able to transform into an esper at will for the base randomizer. This however doesn't rule out the possibility to have an option to randomize the Morph sprite (esper Terra form) into a random sprite either.

By useless, I meant that it really couldn't (or rather shouldn't) be used as a primary character skill... it's only used by the ghost guests and even then only for one dungeon.  In that respect it is a prime target for replacement with another command, as is Health (used for one auto-scrolling sequence) and Shock (used for one battle).

As for turning into a moogle rather than an esper, it was a suggestion intended only to simplify the sprite swaps, as no male equivalent half-esper sprite existed and a moogle would not require testing the gender of the character assigned morph before replacing the tiles.

That said, I gave making a male-equivalent half-esper a shot by splicing Esper Terra with Umaro, and it turned out fairly well.  I've attached my attempt to the bottom of this post if you care to have a look, and AtmaTek may use it freely when he moves into the next phase of developing his randomizer (at the moment I suspect he is still working on event gating).
