The Adventures of Wiglaf and Mordred is a humorous comic about Wiglaf (our hero) befriending Mordred (our villain), by force if necessary. It's also about Mordred's super villain family, their cronies, their friends, and pretty much everyone else that happens to drop in or appear in the background of a strip (see Loads and Loads of Characters).
This comic provides examples of:
A Boy and His X - It would take a crowbar and an act of God to separate Safir and Wolfy... and that's before Arthur Sr. and Geoffrey attack.
Wolfy has yet to display life-changing tendencies, but he is the only non-possessed possession in the comic.
The early comics look mighty like a mercenary and his serial killer possessed sword when it comes to Azrael and Grace. Especially when it's momentslikethese.
Ben and Éclat, almost as bad as Azrael and Grace.
Most surprisingly is Mordred and Bliss. Although not as bad as Azrael and Grace, he does seem to be developing some of the 'can't be parted' tendencies as he pointed out here.
The Ace - Wiglaf was created to be a subversion of this trope. He's perfect at everything... but because he's perfect at everything, people can't stand him. He's also got an almost obsessive-compulsive need to fix things.
Artifact of Doom - the Sword of Grace and the Orb of Bliss, possibly the Sword of Eclat and the Sword of Prudence.
And quite possibly Ring of Jade, though so far all that is know is her name-courtesy of Grace here- and that Word Of God says she's a Ring(and a she). Since the powers are unknown, Jade may not fall into the Artifact of Doom category.
Wiglaf (and others) probably consider Camlann this due to his Wall of Text rants and the fact that he keeps burning the hands of everyone(save Wiglaf) who touches him
Azrael has one towards art pieces and artifacts being stolen. He threatened Generic upon learning about his stolen Ming Vase, Picasso, among other things.
Bliss, to a lesser extend when someone handles/touches her orb. She blasted Wiglaf when he touched it, though she doesn't seem to remember this fact at all when Mordred brought it up mere seconds after. And most recently discovered is people fighting.
Criminal Amnesiac - Gawain, somewhat. See, he can regenerate from injuries, and he considers Arthur and Sedrick his arch-enemies...but he's been shot in the head so many times he can't for the life of him remember why. So in the meantime, he figures a steady paycheck and a job as a Garrott henchman won't be such a bad thing, at least until he remembers.
Dude Looks Like a Lady - Azrael really needs a haircut. Those long, red tresses make him look like a her. Inverted with Driver, who suprises everyone when they discover that "he" is a "she". In fact, the only way to detect that she is really a lady is the fact that there's no Man-Toe when she wears lingerie.
A good portion of the male cast qualifies, actually. Earlier in the strips run Wiglaf was routinely mistaken for a girl. Word Of God says this was at least part of the reason his hair got cut in later strips.
Azreal has since gotten a haircut, making him look a bit less feminine.
Flowers and similarly herbaceous objects have been used repeatedly to delineate Lancelot's, Mordred's, and Driver's personalities and dispositions.
And the decorative hilt on Grace's sword, that's flower-like.
A non-canon portrait by the author once used a daisy to illustrate Wiglaf's personality.
In the event of Azrael's redesign, "457. Going to Catch Flies," Liliy placed small, pink, scattered flowers on his white trousers.
Fluffy the Terrible - The Sword of Grace is a manipulative psychopath, and the Orb of Bliss might be worse. Ironically, Wiglaf makes Mordred go on a quest for the Orb of Bliss specifically because it sounds benevolent.
Bliss seems to be benevolent, if a bubbly airhead.
The Sword of Eclat is an unknown quantity, yet, but he is a male chauvinist and takes great delight in tormenting his owner, so "eclat" does not quite suit.
Funetik Aksent - Driver and Galen both speak with very heavy accents (southern and Russian, respectively). In Driver's case it's shown in The Rescue arc (and Word Of God) that she gets it from her father, who also has a noticeable southern accent.
Girl with Psycho Weapon - The Valkyrie Sisters each wield deadly weapons of one form or another (except for Svafa, who is a deadly weapon).
Grace. The only ones who can see him is Azrael and, for some reason, Gawain. Probably because of the whole Zombie thing.
Bliss and Eclat also fit this trope, and are also probably visible to Gawain.
Karma Houdini - All of the Garrotts and everyone who works for them, to a greater or lesser extent, except Boudica. Azrael, apparently a known and wanted serial killer, is even able to casually attend a probably-televised concert and greet the famous pianist.
Let's Get Dangerous - Surprisingly Mordred to an extent. Seen when he holds his on against SEDRICK of all people. As Word Of God stated, 'Someone had to take after dad'. Of course, as soon as Wiglaf returned he resumed his act of being 'oh so helpless'. Of course, thisleads one to wonder, just what he could be capeable of if he wasn't so lazy.
Loads and Loads of Characters - WAM has a constantly expanding cast of characters. Currently it sits at 52, with a number of dragons having also made an appearance.
Nigh Invulnerability - Word of God has stated that, although the artifacts are magical they are not indestructible, but it would take a lot to destroy any of them and that it is very hard to do so. Example: Mordred stuffed the Orb of Bliss into a box and dropped it out the second story window. It was returned to him unharmed (but angry).
Mordred seemed ignorant of Wiglaf's hero persona, but later revealed to Driver (and the audience) that he'd know since the beginning. He just enjoyed bossing around the his brother's rival, and figured Wiglaf wouldn't have put up with it had he.
Another time was with Arthur, who'd been shown insisting to Sedrick that his male dragon Gustave had indeed laid eggs. In fact, Gustav's species is able to spontaneously 'change it's sex in order to procreate', something that Arthur was fully aware of despite acting stupid about what was going on and Sedrick was not aware until he looked it up while trying to prove Arthur wrong.
Odd Couple - Wiglaf and Mordred, and the basic premise of the entire comic.
Overlord Jr. - Apparently the original intent for Safir, but subverted in practice.
Our Zombies Are Different - Gawain is a zombie. He is also pretty much indistinguishable from a living person apart from the fact that he regenerates from every injury. Although, injuries can have lasting effects, as being shot point blank in the head causes him to lose some important memories. It is unknown what you would have to do to rekill him for good, or even if it's possible. Headshots certainly don't work.
His amulet seems to have something to do with keeping him "alive".
Papa Wolf - Do not talk to Safir without talking to Geoffry and Janus first. Geoffry will fuck you up.
Pre Explosion Glow - Bliss, when she gets very angry. Her silvery-blue orb, turns blood red. That's when you know to duck and cover.
Grace explained that he was part of a set, and Word Of God explained that all the objects in the set were once human, though none lived at the same time: Grace was from Medieval Ireland, Bliss from Victorian Era England, and Éclat from France during the French revolution.
Sliding Scale of Undead Regeneration - level four, Gawain only feels pain when he first takes injury, and can stick any bits that get chopped off him back in their respective sockets. He also doesn't degenerate, although his flesh and skin slough from his bones when he touches an Anti-Magic field.
Actually used to describe the comic in at least one review: "The Adventures of Wiglaf and Mordred, who are hot for a wall-o-text". Most often perpetrated by Mordred, though the most obvious example is anytime Camlann is removed from his sheath, especially the first time after Wiglaf and Mordred fly back to the US after retrieving him.
Anytime Camlann opens his mouth really.
Bliss after Mordred tried to throw her out a window to shut her up-with no success as she was brought back back Julian.
Possible Wild Magic - Camlann's background has not been sufficiently explained, and he cannot interact with the possessed objects, so he is likely to be a different sort of magic, possibly wild magic since he is sentient and willful.
Writing by the Seat of Your Pants - With general ideas of plot direction, Liliy tends to leave dialogue until the day she creates the page and occasionally incorporates gags suggested by family members or U Stream attendees.
Yaoi Guys - Most of the male cast qualify. Lampshaded in the filler pinup "Traumatized Yet?"
Yandere - Sedrick in the latest arc (as of october 2011). So much. See this.
Your Cheating Heart - Linnéa, Wiglaf's mother. She's married to Vilhelm, but has been having an affair with Lennart for likely just as long. Vilhelm knows about it too. Lennert also happens to be Wiglaf and Brat's biological father.
