He does, but this boss is restricted to one map (per boss battle) instead of multiple like Azehr...
Cibryll called him a "butt monkey" once... he keeps meßing up with his entrances... "Hussar" or "Hurrah" instead of Balrog's famous "Huzzah"...
Except on floor 24... there he is just plain ANGRY... with no usual antics...
That reminds me. Considering that Balrog is an entity, that means you could have multiple Balrogs in a single map if you wanted an extra fight where Fantome has multiple phases. Then again, Apocalyptic Shadow does sound interesting so I do look forward to seeing how the Famtome fights play out.
