These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Is Doc a hero, a villain, or a Well-Intentioned Extremist? Is King Radical an Anti-Villain, a hero, or a Villain with Good Publicity? The latest arc confirms him as the last. He's bent on merging the universe with his radical land, killing people he deems 'boring' or 'jerks'. So far, he's only tried it on people that the Alt Text says have done crimes too heinous to mention in the comic, but there is no indication he will stop there. With the death of Mr. Andrews, who was just a cranky, lonely, sick man, it becomes almost impossible to justify his radness' scheme.
The title character shows moments of being somewhat mentally unbalanced, but always in ridiculously cool ways. For instance, in one arc he is inspired to go rescue his estranged family from a shipload of pirates by a talking roast turkey, who explicitly tells him that it's an illusion. In the next arc, he attempts to find out how a Velociraptor got into his office by busting through a skylight in a warehouse and accosting some random burly types, because his decision-making process is based on "What Would Batman Do?" He comes by this honestly, as his father's favorite way of evading pursuit is to set himself on fire, because, "They can't grab me if I'm on fire." It's gotten to the point where Dr. McNinja is now its god in the Pantheon.
A good example here. The Amazing Flying Shooting Juan.
And from that trope's page:
Dr. McNinja: Oh. How stupid of me. That was the sound of chainsaw nunchucks.
Dr. McNinja jumps off the moon, completely unassisted, carrying a Dracula-bot, and then proceeds to SURF said Dracula-bot to Earth's surface.
Also, Doc and Frans. And Dan and Frans. Everyone's gay for Frans?
Now, Doc and King Radical.
Heartwarming In Hindsight: In one of the early arcs, Doc tries to solve a mystery by asking himself "What would Batman do". In "AWOL MD" we learn that he does things like that because he loved Batman comics growing up and they inspired him to the hero and nice guy he is today.
Hilarious in Hindsight: Kate Beaton's guest comic had McNinja not knowing what do to his potato garden. Flash forward 2 years to the Army of One storyline, where it turns out the clone in charge of learning agriculture didn't make it to the amalgamation.
For the author, this page, since it was written days before the US President's announcement of the death of Osama Bin Laden, public enemy number one, and happened to be posted twelve hours afterward. For everyone else, it felt like it was Ripped from the Headlines (unless they had only just found out from the Alt Text).
Anyone remember Archibald, king of the hobos?
Inferred Holocaust: When King Radical turns the buildings of Cumberland into a Giant Mecha, how many people do you think died or were seriously injured while their entire houses were floating through the air? Let alone while the mecha itself moves around.
Jerk Ass Woobie: King Radical. He just wants to make the world a cooler place, and when he talks to Dr. McLuchador/McNinja about Radical Land, you can almost feel the longing in the text. Almost had another example in a recent comic when Herschel explodes and looks terrified, but is overjoyed by his replacement.
In "All The King's Dirtbikes And All The King's Men" we learn that Sparklelord became evil partially because the then-current King Radical (back then our King Radical was just Sir Sicknasty) and his allies destroyed his home and people just because they weren't cool enough. Ouch.
This could count, especially if you grew attached to the lovable goon. Poor Herschel...
What an Idiot: The president landing Marine One on the Radbot's hand and not even bothering to keep it running just in case Rad should decide to...you know...move the hand. This even lampshaded in the alt-text.
Similarly, assuming that King Radical would be willing to hand over the Radbot in exchange for a simple case of Mountain Dew Code Red. To be fair, Radical didn't actually go back on his word, that just doesn't mean he'll stop Ron from doing it for him.
