Tous pour un, un pour tous

Tien splits his body into four separate Tiens, with a total of 12 eyes. Goku gets knocked down by their first attack, but used the opportunity to find the two weaknesses in this skill: the 12 eyes are too sensitive and each Tien is only a fourth as strong as the actual Tien. Goku uses Tien's own Taiyoken technique against him to blind the 12 eyes, and then knocks all four Tiens out of the ring for the victory.  (Source: Wikipedia)
