Sephiroth from Final Fantasy VII is generally held up as the most extra Square Enix boss, but I think Chrono Trigger brings very stiff competition with a final boss whose battle anthem is just a remix of the game over music, and who makes you watch an unskippable two-minute cutscene of the world being destroyed every single time you lose the fight.
I mean
Chaos: makes everyone relive the same 600 years so he can avoid dying
Zeromus: says he’ll never die as long as hate exists
Kefka: has his own cult and a tower and a contrapuntal organ solo
Ultimecia: wants to flatten time, has a castle with a wine cellar but no face
Exdeath: literally a tree
