The song, which is, as Prokopis pointed out on Purrsia’s board, a low-quality mp3, is by a children’s music group called Trem da Alegria (Happiness Train). You can read about them on Wikipedia.
The lyrics and translation are below. In the translation, I’ve parenthesized and literal translations of interest, as well as instances where I translated a bit more liberally so that the English wouldn’t sound weird.
Interesting differences between English ThunderCats and Portuguese ThunderCats:
The Sword of Omens = A Espada Justiceira. Justiceira does not have a good English translation. It’s a bit stronger than “just”… more like, strictly observing and promoting justice, like a policeman.
Sight Beyond Sight = A Visão Alem do Alcance, or Vision Beyond Reach
Lion-O = Lion
Jackalman = Chakal
Monkian = Simiano, as in simian
SSSlithe = Escamoso, or Scaly (ha!)
Also, the song adds two new elements to the Code of Thundera: Courage and Wisdom. Pretty cool, huh? … or at least, it lists these two amidst Justice, Truth, Honor, and Loyalty.
Okay, I’ve blabbed enough. Now, on to the lyrics!
ThunderCats, Trem da Alegria
Thunder, Thunder, Thunder, ThunderCats!
Thunder, Thunder, Thunder, ThunderCats!
Cortando o ceu escuro de um mundo perdido
Lion e seus amigos numa nave estrelar.
Cheetara, Tygra, Panthro, o Olho de Thundera
Avisa do perigo que ja vai chegar.
Mas só quem luta pelo bem é invencivel
A chama da justiça nunca vai se apagar.
CORO:
Thunder, ThunderCats
Aventura, ThunderCats
Fantasia, ThunderCats
Companheiros,
Na luz da Espada, no brilho de estrela.
Thunder, ThunderCats
Aventura, ThunderCats
Fantasia, ThunderCats
Companheiros,
Na luz da Espada, no brilho de estrela.
Chakal e Simiano, o cruel Escamoso,
Mumm-Ra, o Mal Eterno, chefe dos Mutantes,
Comanda seus vilões e tenta mil maneiras
De conquistar seu mundo e a Espada Justiceira.
Mas só quem luta pelo bem é invencivel
A chama da justiça nunca vai se apagar.
CORO
Visão alem do alcance
A fonta do poder
A honra e a verdade
Coragem e saber
Justiça e Lealdade
Pra sempre vão vencer.
Thunder, Thunder, ThunderCats
Ooooooooh!
CORO
Thunder, Thunder, Thunder, ThunderCats!
Espada da justiceira, dême a visão alem do alcance!
Visão alem do alcance
A fonta do poder
A honra e a verdade
Coragem e saber
Justiça e lealdade
Pra sempre vão vencer.
Thunder, Thunder, ThunderCats
Ooooooooh!
CORO
Translation
Thunder, Thunder, Thunder, ThunderCats!
Thunder, Thunder, Thunder, ThunderCats!
Cutting the dark sky of a lost world,
Lion-O and his friends in a spaceship.
Cheetara, Tygra, Panthro, the Eye of Thundera
Warns of the danger that is upon them (that is already arriving).
But only he who fights for good is invincible,
The call of justice will never be silenced (extinguished).
CHORUS:
Thunder, ThunderCats
Adventure, ThunderCats
Fantasy, ThunderCats
Companions
In the light of the Sword, in the starlight.
Thunder, ThunderCats
Adventure, ThunderCats
Fantasy, ThunderCats
Companions
In the light of the Sword, in the starlight.
Jackalman and Monkian, the cruel SSSlithe (Scaly),
Mumm-Ra the Ever-Living, leader of the Mutants,
Commands his villians and tries a thousand ways
Of winning his world and the Sword of Omens (Justice).
But only he who fights for good is invincible,
The call of justice will never be silenced.
CHORUS
Sight Beyond Sight (Vision beyond reach),
The source of power,
Honor and Truth,
Courage and Wisdom,
Justice and Loyalty
Will forever win.
Thunder, Thunder, ThunderCats
Ooooooooh!
CHORUS
Thunder, Thunder, Thunder, ThunderCats!
Sword of Omens, give me Sight Beyond Sight!
Sight Beyond Sight,
The source of power,
Honor and Truth,
Courage and Wisdom,
Justice and Loyalty
Will forever win.
Thunder, Thunder, ThunderCats
Ooooooooh!
CHORUS
