Gotenks (DBTNG)

"Wait, i was supposed to FIGHT you? I thought my power would just scare you away..."

- Gotenks to Aqan

Gotenks is the fusion of Goten and Trunks and is the strongest character in TNG. He "defeated" Aqan and injured Terris. Right when Gotenks was about to kill Aqan, the fusion defused. Also, when he was beating Terris to a pulp Vegeta got arrogant and used the Galic Cannon on Terris. The cannon gave Terris more power and Gotenks had a hard time with Terris then.
