>>20558242>you worked so hard to get here only to fight thisThat's not it at all. The whole point of Iris is to throw you off. The theme is cute because Iris is a little girl who likes cute things and wears princess dresses for fun, but is actually a fierce trainer and child prodigy.
Blue was a kid champion too. Iris just revels in it much more. She has this "I'm the queen, bitch" attitude, and it's cute how she plays princess dressup while being coarse and unrefined. The whole thing is a nice change of pace from the usual 'wise old master with a hardcore theme.'
