Dragon Ball: West City High Schooler, Captures 18!

Reborn into the world of Dragon Ball. No power? No background? Don’t worry— The Template System will give you the answer. Unbelievable luck— His very first draw turns out to be the legendary man himself! The strongest across dimensions—Gogeta! And it's even the Super Era version! What’s that? You’re saying it’s the Cell Saga right now? Well, what if I told you I have 10 trillion power level in base form—won’t that blow your mind? Wait, hold up— You’re telling me, what’s this situation with 21? Still acceptable. 18, turns out you have a sister now! No, wait… where did these extra 6 universes come from? The Tournament of Power wasn’t enough?! Now it’s a Cross-Time Tournament?! And the losing side’s universe gets erased?! Doesn’t matter— Because I have all your templates. Angel Kus: “My, oh my... be honest, are you an angel? Otherwise, how could you possess such pure angelic power?” Dragon God Zalama: “Are you kidding me? How do you have Dragon God Power?” Grand Zeno: “Yayayaya! Where did you get the power to erase things?!” [Raw: 龙珠：西都高中生，俘获18号！]
