It's easy to see the appeal of opportunity upon seeing a gigantic umbreon. If you beat it, it's gotta be worth a ton of EXP and bragging rights, if you capture it, well you have a gigantic umbreon!
However it's never as easy as one thinks, and as far as Moonlight goes, you have a better chance of getting struck by lightning while jumping off a cliff and getting eaten by a shark than winning against Moonlight or capturing him (Artie is a special case cause Moonlight was just bored).
A certain deviltod is learning this lesson the hard way, a lesson Moonlight has no problem teaching.
Art and deviltod belong to Beherit
Moonlight belongs to me.
