Gotenks
Gotenks has the strength of coordinated fusion and the judgment of two excited children who know they have an audience.

A precise method
Goten and Trunks create Gotenks through mirrored poses performed at equal power. A bad angle or mismatched movement produces a failed body, turning technique into visual comedy and making synchronization a real condition of success.
A combined personality
Fusion does not simply place two minds side by side. Gotenks exaggerates qualities the boys share: confidence, invention, competitiveness and a love of dramatic presentation. He names attacks as readily as he creates them.
The battle with Buu
Inside the Room of Spirit and Time, Gotenks develops a wide range of techniques and reaches Super Saiyan 3. His performance against Buu is impressive, but staged suspense and wasted time repeatedly compromise the plan.
Power with an expiration
The Fusion Dance lasts for a limited period, and high energy use can shorten practical fighting time. Gotenks demonstrates the central lesson of fusion: multiplication of strength also creates new constraints.
