In Fusion Reborn, Gogeta is not seen as cocky whatsoever when compared to his Super Saiyan 4 form, and eliminates his enemy quickly. As a Super Saiyan 4 however, he acts somewhat similarly to his Potara counterpart Vegito as they both toy around with their respective opponent in order to achieve their true goal.
He is also the only fusion to be dead, as both Goku and Vegeta were deceased when they fused and fought Janemba.
Gogeta is the only Fused Saiyan character (Potara or Fusion Dance) to successfully defeat a villain without the fusion wearing off (he defeats Janemba without even coming close to running out of time).

however, the gogeta cannot be performed by two females in any way shape or form, it is simple physics.
