Note: The submission title is meant to be The Green Ziz-Ziz & the Pink Meteor ("Meega Bigger"/"Who's Laughing Now?" unofficial part three).

What's this? A continuation of someone else's macro growth fanfic for Macro March? Why yes. Yes it is.

So back on Stitch Day 2020, macro writer   Dragonien wrote and posted a Lilo & Stitch macro and growth fic called Meega Bigger, an alternate continuation of the Lilo & Stitch: The Series episode "Short Stuff" where Gantu grows Experiment 625, who is somehow named Reuben before Leroy & Stitch happened here, bigger than what we last saw him in that episode, only for Stitch to become even bigger than him and devastate the entire island of Kauai in the process. This fic got quite a bit of attention; even  maxpany, whose macro art of Stitch and Reuben was one of the inspirations for this headcanon tale, made some fan art for it, even creating some drawings depicting events that might happen after the story ended.

Not to leave the story as a one-shot with a cataclysmic ending, Dragonien later decided to make a second part based on those extra drawings called Who's Bigger Now? where Reuben turns the tables back at Stitch and grows much more bigger than his "cousin" (or "brother" here), absolutely bulldozing Oahu in the process.

And... That was it. Despite the cliffhanger ending, there was no part three that followed afterward despite the potential for more from these two's "size war". I actually decide to make my own follow-up to that part not long after Who's Bigger Now? was posted, well before it became clear that the original author wasn't going to make a third part anytime soon.

I actually had a few ideas of what could be added to the story; the biggest one for me was figuring out where the rest of the 'ohana were when Stitch and Reuben's size war began. I didn't like the possibility that Stitch would inadvertently kill his family from his major growth spurt and destructive playtime, so I had them being off Earth by the time Reuben and Gantu would come to Stitch for their eventual size fight. Plus, I thought, 'Why not have Angel thrown into the mix? We can't leave the last of the experiments' power trio out of the fun!'

It actually took me a lot longer to get around to finishing this. A few days after I started writing this, I had an accident that took me out of commission for a while. I recovered after a couple months, but I didn't really get back to this story for over a year up until just recently. I think I rushed the ending a bit just so I could call it finished, but I've at least I've finally made my new addition. Besides, this is all for some silly macro fun anyway; it's not like it's going to be the next great epic! (Well, apart from the epic sizes of our leads. XD) And I have some ideas in mind for a part four, but I'm going to just keep them in mind for now.

Anyway, I hope I've reinvigorated some interest in this story for you macro Stitch lovers out there!
