Saint Seiya (1986)

S1E14 Defeated! Genma Ken!

The four Saints gear up to confront Ikki, who, as it turns out, is still alive despite previous beliefs about Hyoga's demise. However, they quickly realize they are no match for Ikki's overwhelming cosmo, as he takes them down with a single blow, leaving only Seiya standing, shielded by the Gold Cloth. Drawing strength from the cosmo of his comrades, Seiya fights valiantly and ultimately prevails against Ikki after an intense and grueling clash.
