Hyper SakaChukaen is the first Hyper Gattaien made out of more than one Jakaen commanders. This fusion was made from Sakaen and Chukaen.
The form has Chuckaen's wings, head, and tail, with Sakaen's face on the chest, and the rest of his body.
Hyper SakaChukaen was able to withstand the power of Great Wyvern. X-Dragon Robo and GaiaLeon lunged at it, but was fended off. When Fire-1X gained the blue orb of Faith, Rescue Fire was able to form the largest vehicle combination, Great Wyvern GX. Great Wyvern GX destroyed the fusion, sending Sakaen and Chukaen flying.
