Freddie the Flying Fetus alternates between exceedingly happy and having a lot of unfortunate things happen to him.
Stumpy, a humanoid tree stump, is arguably the Only Sane Man in the comic, except for when real people make an appearance.
Recurring fictional characters include Plantae, a supervillain with plant powers and Remora Joe who has two fish attached to his face. Lovebot is almost a spinoff in his own right. Bob once made a robot designed to love and set him loose For Science!. He's still out there.Non-fictional characters are mostly one-offs, with the exception of Kofi Annan, who has accompanied Bob on monster-killing missions, evaded ill-defined pursuit and it gets weirder.Find it here.
I was surprised to learn from the opening credits that the name of the movie was Battle Los Angeles. Not Battle: L.A. or even Battle: Los Angeles, but just Battle Los Angeles. In a way, just typing it out now, it's brilliant. Because the movie is all about battling Los Angeles.
Not in a good or entertaining way, mind you, just as battling Los Angeles would not be a fun or enjoyable experience. No, Battling Los Angeles would be a lot of running around, taking cover, wondering what the fuck was going on and then eventually getting to shoot at some clunky terminators with blobs for heads. But, after all, isn't that what we should expect from a battle with Los Angeles?
Couch Gag: The title is drawn differently every time. Extreme examples can be like this◊.
Crapsack Only by Comparison: In one comic, Bob dies and goes to heaven; he realizes that everything up there is so awesome that people still living on earth are in agony, relatively speaking. He then jumps down to earth, saying "I've gotta kill everyone!"
Negative Continuity: Bob has repeatedly raised vast evil armies and reduced the earth to ashes, or fed every living thing into the mouths of Lovecraftian horrors, complaining all the while how people just don't have his vision. It never sticks.
No Name Given: Subverted by The Nameless Ones, who openly admit that their name is The Nameless Ones.
Ray Gun: Bob has all sorts, from a peace ray that Time-Grabbed Jesus tries to steal, to a seahorse ray and even an unexplained Donut Ray that appears to be meant to show all his enemies in one go that he could have killed them but chose to give them donuts instead.
Freddie appears to have a ray gun capable of destroying Plot, when the storyline insists his attempt to save the day will fail.
Invoked in Achilles' Heel◊ - but subverted in that, whatever Ultraman's weakness is, Bob's got it embarrassingly wrong.
What Kind of Lame Power Is Heart, Anyway?: Reference Hamsterfall. There is also Plantae, the villain with plant-controlling superpowers, who ends up broke and jobless because plants can't actually do anything much.
