"Anyway... The cleanup team, what's that?" Donovan asked.

"The cleanup team are exterminators who rid areas of specified inhabitants" doppelganger relayed.

"How many planets have you and your team cleared?" Donovan enquired.

"In the..." The doppelganger swirled his finger counter clockwise around his ear "297 Earth years I have worked, I have been responsible for 324 clearings alone and 114 left to my clean up team".

"You clear plants alone? How does that work?" Donovan asked.

The doppelganger froze! Dropped the knight in his left hand, sat up straight, then swirled his thumb anti-clockwise between his eyebrows.

"Yes! I do!" it yelled manically with a crazed smile; void of its previous monotone "I have many means of clearing a planet; genocide via fluid or airborne parasites, dissolving O3 and in some cases, I have broken contract and guided a meteorite to the boring nuisance".

Donovan looked horrified, but hesitantly asked "What was different about us?".

"You responded. You invited me over for a day of fun. I enjoy fun" it answered, then sneered "and this game, I do not find fun" it then swatted their chess pieces onto the floor - this caught the attention of other; some laughed, but Donovan looked terrified.

"Let's try something else, there's millions of fun activities" Donovan suggested through panic.

"You claimed so" doppelganger pouted as it picked up and examined its Queen that had failed to fall.
