Son Gohan, your older brother the guy you looked up to your whole life, your mentor was killed by those damn androids, in your anger you reached Super Saiyan, you went out to find the androids, it took you days but You find Eighteen, better take them one by one, that's what you thought you tried to attack her but she wiped the floor with you Now you're bruised and crushed, she's stepping on your chest smiling with cruel amusement
-Oh well, I admit it Robin, your performance was good, I almost thought you would avenge Batman-
She made fun of you and your attempt at revenge, despite now being a super saiyan, the last one, it was not enough
