Les began his own line of comics called Brain Sucker. The main character is a gray scorpionfish monster who had the ability to drain the intellect from anyone (by merely doing what his name suggests - sucking their brains), even Nano and the Hillhurst monsters (minus Frankenbeans, who apparently had no brains for the monster to suck on). Brain Sucker was created, according to the story, by the Monster Mother herself, and was hatched from an egg she laid in her lair. In battle, Brain Sucker could blast sharp darts from its mouth. The Data Lasers did this hideous creature in once and for all. After this, Nano, the Hillhurst monsters, and all of the Brain Sucker's other victims regained their intelligence.
