We're playing with the rules a little here. In canon, they don't transform in different worlds. *shrug* Whatever. xD;
Anyway, We discovered this:
Title: Roxas and the Chipmunks
Characters // Pairings: Roxas, Axel // AkuRoku?
Rating // Warnings: G // none
Canon: Kingdom Hearts 358/2 Days?
Summary: Axel is amused, and Roxas bites him.
"What are you?"
The massive black lion's muzzle spread in a wide grin, and Axel lowered his face parallel with the ground. "Well, isn't that cute."
"Shut up," again, and then there was a red mark across his nose. VIII shook his head, red mane shaking, then reached forward with a round paw, batting the rodent out from in his face.
"Not very nice, chipmunk."
Roxas scowled. And scowled.
And scowled some more.
And when terrible little chipmunk teeth came down upon the Flurry of Dancing Flames' ear, he couldn't help but feel he really, really deserved it.
- roxas and the chipmunks.
