User blog comment:Pandawarrior/What if Luffy and the SHs had joined the Whitebeard Pirates?/@comment-3986064-20111210120117

OP would have been way more epic for sure till now. We've all seen Whitebeard. Luffy would've been doing lots of things for Whitebeard, learning haki faster, training his Devil Fruit while eating lots of meat. He'd surely have been one of the favorites on the ship. his progress wouldn't have been so fast, since his motivation(protecting his crew) would've been lost. Unless he thought that one day the old man will lose and he'd have to take care of everyone(which seems very unlikely since we saw just how epic WB is)

There would've been no Franky and Brook for sure. But I wonder if Robin would've joined, if she knew how WB was, she would've have joined him from the start, as such a great father.

The war would have still happened, but all the SH would have taken part in it which would be kinda horrible for Luffy, risking his crew's life at Marineford. The War of the best where even he was weak compared to many others.(Even though he still did a lot of things there of importance).

I think Luffy would've still found out Gear Second, WB is still a great model to look up to so I can be sure that Luffy would have done his best to become the best.

After the Marineford war he and his crew would have separated from the others and Luffy would've found his way to becoming the Pirate King.
