Black Smoke Shenron Returns
After Son Goku left with the eternal dragon Shenron for special training, Trunks volunteered to return the still corrupted dragon balls to Dende to be fixed. Soon afterwards, Black Smoke Shenron leaves the dragon balls, once all seven are put together, and possesses Trunks' body, increasing his power beyond his previous limitations. Now attempting to kill Dende, to split his life force from the dragon balls forever before the negative energy he's made of can be cleansed, Vegeta stops him, and they prepare to battle.
Combating the Z-Fighters
Dark Trunks first gets to test his power at Kami's Lookout against Vegeta. Despite his best efforts, Vegeta can't land a single pucnh on Dark Trunks, forcing him to ascend to the level of a Super Saiyan 2. In this form, Vegeta fares much better against his enemy, but Dark Trunks still isn't phased. In a desperate attempt, Vegeta fires his galcik gun. However, Dark Trunks knocks the energy wave away with his knee. The Look Out is literally rocked by their bttle, and so is Vegeta. Dark Trunks comlpletely humiliated Vegeta, but before he can finish him off, Uub appears.
Dark Trunks is in a league of his own. The amount of negative energy brought into Trunks' body by Black Smoke Shenron has increased the saiyan's ki reserve exponentially, greatly boosting his power level past previous limitations. In a normal state, Dark Trunks can easily dominate Super Saiyan 2 Vegeta at full power, using an equivalent of only 1% of his own strength. Not even the power increase granted by the Super Saiyan 4 state gives Dark Trunks much of a problem.
