Ooo-Kay, I got this idea from a dark pokemon fan-fiction that I read years ago.
It featured Ash and pikachu, but pikachu had evolved into a shadow pikachu.
I thought I'd do a pic of shadow chu & put him next to a light chu.
(I'm told the story has a light chu as well, but I kinda forgot about him
it was a long time ago)
So anyway they're both from that old fan-fiction, it's prolly still floating around online somewhere...
Aren't they cute?...
EDIT: Long overdue update, didn't change too much, I just improved the colours, contrast etc, looks much better. Enjoy.
