Offering a Star-Busting Bomb to the Wonderful World

Can't decide what to do?

Kaioken.

Spirit Bomb.

Kamehameha.

If that still doesn't solve the problem, go straight to the Planet-Busting Bomb.

(Just so we're clear, the early story is Dragon Ball, and the main world will remain Dragon Ball in the middle and later parts, though the plot will shift to a crossover with various anime. If there's an anime you'd like to see, leave a comment. I'll check it out when I have time.)
