Descomunal translates to "colossal" or "enormous," but it carries a sense of being out of the ordinary, almost monstrous in scale. It's a less common word than simply "grande" (big) or "enorme" (enormous), making it more impactful.
In "Lucha De Gigantes," the lyric "En un mundo descomunal" (In a colossal world) uses this word to evoke a feeling of being overwhelmed and small in the face of immense challenges or a vast, intimidating reality. It perfectly captures the song's theme of struggle against something much larger than oneself.
"Lucha De Gigantes" ("Fight of Giants") is about feeling small and fragile in front of an enormous, overwhelming world. The singer describes the air itself turning heavy, a wild danger closing in, and a beast chasing right behind him — a picture of anxiety that feels bigger than he is.
He asks someone to tell him it's all just a bad dream, admitting how scared he is of that enormity, and of a world where no one hears his voice. He calls out a "paper monster" — a fear that looks huge but is actually flimsy once you really look at it — and confesses he doesn't even know who or what he's fighting.
By the end, the song turns into a plea: let us pass without fear. It's a duet between Raphael and Mikel Izal about facing what feels like a battle of giants, and finding the courage to keep walking through it anyway.
