I think it goes without saying that I do not own Yu-Gi-Oh!, for, if I did, I doubt it would have gone anywhere. There is too much fun to be had in trivialities.
The instant Ryou adorned the Ring in the privacy of his bedroom, the Spirit took over. It was easy. The boy's meek nature bent and broke light a dry twig beneath the pressure of the Spirit's dark influence.
Starting from the head down, Bakura fell into his new body, liquid metal filled into a mould. His fingers and toes poured in last. He wiggled them experimentally.
"Yes," Bakura growled. He extended his arms in a mighty stretch. "Alive!"
He hurried to a mirror to assess his new body. He froze in his tracks upon seeing his reflection.
"What the living hell?!"
He was… scrawny! Aghast, he leaned close to the mirror. His skin was nearly poreless, silky smooth, untouched by sun.
He ripped off his shirt.
"By Zorc!"
His real body had been chiseled by hard work and darkened by the desert sun. This was… this was…
"What a feeble attempt at being a man!" he snarled. He was, dare he say, feminine! Thin, soft-stomached. He yanked down his pants. He nearly whimpered in horror. "I've got reeds for legs." He took his socks off. Slender, womanly feet. These fine-boned hands... these feet... had never seen a day of work in their lives.
Even his hair! It was… disgustingly well-kept. He passed his fingers through the locks.
His mouth dropped open. So soft…
He scowled. "This just will not do."
Yes, a strenuous dietary regimen, some laps, some strength-building, hell, maybe even an agility course...
This was nothing a little exercise couldn't fix… right?
END
I just don't imagine Bakura being content with having a kid like Ryou as a host. Especially considered his original body… you could grate cheese on that man's abs.
