Kaboom Baby!

And so begins the fine tradition of destroying everything people hold dear in order to recruit them as crew members.

NOT HERE TOO!
teh end of all webcomics is neigh!

No webcomic is safe. Except Sluggy. Can't stand Sluggy.

Huh?! Guess the anime was different from the manga. Because Luffy used a Gomu Gomu no Ballon to send back the cannonball.

Edit: Just so it is clear, I meant I remember him using that move in the manga.

He made a habit of that later in the story, but back at the beginning he actually tried to send them back like that.
...Maybe he stopped because even he thought it was too impractical.

...Luffy? Thinking? HA
