Kecleon, the Color Swap Pokémon. Kecleon is able to blend into its surroundings by changing the color of its body.
– Ash’s Pokedex
Kecleon is based on a chameleon, which is probably why its ability is Colour Change, which turns its type to the type of the move that last hit it. It’s a fun and novel idea, but not very practical, ie, the ability makes Kecleons easy to kill, since its type can be changed predictably.
In the anime, even though Kecleon can turn invisible, its belly stripe couldn’t be hidden.
So for this wallpaper, I made most of Kecleon semi-transparent, except the stripe.
