Been a while. Missed out on rating and voting on so many tourney entries. My bad.
Good entry, broadway. It's a good story and everyone's in character. One quibble, though: if Kimberly grew to Arcee's height, she'd actually be around 12-15 feet tall.
As for the match, Arcee from the '80's 'toon never impressed me much with her combat skill. The show seemed more focused on just making her the "girl" of the Autobots. Her Cybertronian build may give her a durability edge against Kimberly, but I still think Kimberly has the edge in this one.
That might've been tricky. The admin panel on the profiles has been on the fritz lately.
