THIS! IS! INSANE!!

WE ALL KNOW TERRA'S LINGERING WILL IS LIKE THE HARDEST BOSS IN KH HISTORY

IF NOT IN ALL VIDEO GAME HISTORY

WELL




NOT ANYMORE

The magic formula is Fenrir (whose auto ability is negative combo) + negative combo ability NO COMBO PLUSES OR AERIAL FINISHERS OF ANY SORT and.... that's it.
The two negative combos mean you go straight into a finisher w/ your first attack and... this happens

(a slightly easier way to do it is to start off the battle with Donald's Comet/Fantasia ability, so that he's vulnerable right off the bat and you don't have to wait for him to stand still)

It works on other bosses (or, data battles), too


I actually... this is how I beat Terra... and I feel.... I feel kinda bad omf

I'll rematch him later and beat him for real just to. really just to prove I can do it

A full breakdown of this battle/his AI/moveset/etc is in this wonderful video by Everglow8444 (the same person who did the fantastic english dub of this battle)



You can also see them fight the Lingering Will here, which brings up some further tips not mentioned in the definitive guide--like using a Blizzaga + Thundaga to finish off your string of combos and deal extra damage. (Or... perhaps that WAS mentioned in the guide....)
