A Form You Are Comfortable With: The basic reason Két changes form on occasion when world-hopping. Essentially, it'd be weird for an anthro cat to be walking around on, say, Pop Star, so she changes to a form better suited for that world.
A God Am I: Silverado is the God of Death from one of the Crossroad worlds, and he's not exactly shy about saying so.
Ambidextrous Sprite: Averted by Két, who has different sprites based on which direction she's facing. Played straight by everyone else, most noticeably Blair, whose BFS will swap the direction it's facing based on which way he's facing at the time.
Art Shift: Some pages have a drawn image on them, when Niv feels that sprites can't properly convey a picture.
Aside Comment: Periodically, text will appear near characters that are not necessarily in speech bubbles. These aren't often acknowledged by other members of the cast, and seem to be more of an immediate reaction or a small indication of what exactly is going through their mind at the moment.
Asleep for Days: Damaru was out for three days after his fight with Blair. It's discussed in the comments. Két's out for a week after her run-in with Blair.
Trainphantom16: It's always seems that someone gets knockout for about 3 or 4 day
Niv: Well, 3-4 days is enough to emphasize how exhausted someone is, but not enough to warrant being worried about being in a coma or something like that. It's a nice, happy medium.
Ax-Crazy: Blair. Seriously. His upbringing probably didn't help - he was apparently raised in a society where the strong get what they want.
Bad Liar: Két both subverts and plays this straight. If she's confronted about not being honest about something - IE, the exact nature of her powers - she's not very good at lying her way out of it. However, when given wiggle room, she's very good at distorting the truth - while she's not technically lying, she's not being entirely honest, either.
Beat: Alternates between being used for comedic effect and dramatic effect, but still employed somewhat frequently.
Beat Panel: Niv's preferred method of using this trope. Characters will often take an entire panel to comprehend what just happened to or near them.
Behind the Black: Thanks to her abilities as an aware, Két can do just about anything off panel. This includes untying herself, leaving while someone's talking, and moving to outside of the comic's boundaries.
However, this also works in reverse- Két has trouble seeing things that are off-panel. A bunch of robots manage to sneak up on her this way.
Big Bad: Silvena, the character who is giving Damaru and Silverado orders. She is expanded upon, but not named, while Damaru is in World , before finally getting her formal introduction on page 200.
Blood Knight: Blair seems to be one. His initial encounter with Damaru has him ask for a sparring match, mostly because he's bored and antsy, and results in a complete and utter curb stomp in which Damaru can't even get a hit in and winds up unconscious for three days.
Breaking the Fourth Wall: Két has, on more than one occasion, left the comic boundaries and hidden outside of the panels, or attacked from outside of them where her opponent can't see her. She is also constantly commenting on elements of the fourth wall.
Breather World: World , Strato City, is one of these. Két takes full advantage of the fact that she has several hours to goof off before Phantom Thief Kiara (the assumed reason she's there) is supposed to show up to go shopping and take a nap. As it turns out, Két herself is Phantom Thief Kiara, and her actual objective is to stop a fake.
The Cameo: Since a few of the worlds are submitted by fans, Két periodically runs into characters who are owned by other authors. So far we've only seen Muddy in World  and Aqua in World , but Niv held a contest with the prize being cameo slots - 7 for World  and 1 for World  - so it's safe to say we'll see more when she arrives in those worlds.
The Charmer: Két is very good at talking her way out of situations, or at least getting a discussion going for long enough that some form of distraction appears which she can take advantage of. This is perhaps best displayed when she re-visits Mobius and effectively stalls Metal Sonic just by talking to him until backup better suited to fighting him arrives.
Character Development: Certain events in the comics will cause Két to take certain actions later on down the line - for instance, Meta Knight informing her that it's better to keep a low profile when first arriving on any given world comes into play not only on World  - where she avoids giving out any personal information until she can come up with a good cover story - but in general, she tends towards using thought bubbles in her initial conversations with Niv when landing on a new world.
Chronic Hero Syndrome: This is both a problem and an advantage for Két. She's always running around trying to help people. On one hand, it tends to get her into trouble with the villains of the world she's on. On the other hand, it often helps her fulfill her objective.
Colony Drop: In World , Cream and Cheese are helping look for the Chaos Emeralds because a meteor is headed towards the planet. They plan to have Super Sonic and Super Shadow either destroy it or relocate it to a place it won't be able to cause damage.
Demonic Possession: World  introduces inhabiting, which Niv likens to this. Két can "inhabit" Audience Surrogate characters, effectively possessing them and taking control of their actions. This is more akin to ghostly possession than demonic possession, though.
Enemy Mine: Két and Damaru are forced to team up in World  for two reasons. The first is that they're both stuck there until Két's objective is fulfilled. The second is that Damaru had become Két's Digidestined.
Flat "What.": The basis of Két's reaction to Cream being able to fly with her ears.
Foregone Conclusion: Damaru's flashback resulted in him becoming Silverado's host. However, the events leading up to this occurrence were largely unknown, so it's expanded on in the form of Damaru and Silverado explaining their predicament to Blair.
Sometimes, events in past worlds foreshadow events in future ones. For instance, Két being able to use her powers as a Gatomon is foreshadowed when she uses them as a Gaw Gaw.
Niv periodically lets slip some details in her comments and responses, such as the fact that Két can revisit past worlds, and she periodically teases the audience with potential information, such as:
She let slip that Két would be visiting either the Mushroom Kingdom, world of Pokémon, Hyrule or Megaman's world in the future. World  is Hyrule.
World  will apparently have a lot of fighting in it. The context here hasn't been revealed yet, but World  is next.
Fourth Wall Observer: Két's lack of a Fourth Wall allows her to be one of these. She can see into other panels, the events of pages that she's not in, and read speech/thought bubbles. However, this comes at a cost - unless Két has prior knowledge in regards to a situation, her knowledge is limited to what's been revealed to the audience. This means she has no idea what to expect when she ends up in Twisted worlds.
Frame Break: While Két hasn't broken the panel borders themselves (...yet), she has jumped between them and at one point uses this to effectively clone herself.
From Beyond The Fourth Wall: Niv serves as this to Két, usually when the latter needs information that the former could easily look up online.
Genre Savvy: Thanks to her awareness, Két knows a lot about what to expect when she goes world-hopping.
Glowing Eyes: Yamaha's eyes glow when his necromantic powers are keeping him stable. Rupph's eyes glow all the time.
Goshdang It To Heck: Niv, upon discovering that World  is actually her friend's comic, The Dark Age of Mobius, uses the phrase "What the fluff!?
Silverado seems to be incapable of swearing, only able to go about as far as "hell" and "bitch". Anything further gets replaced with "squawk" or some variation thereof.
Silverado: Squawking hell.
Grand Theft Me: With a little help, Silverado does this to Damion. Damaru's personality appears to be the result of 40-odd years of dealing with Silverado and generally becoming jaded towards the world(s).
And then it turns out that Silvena wants to do the same thing to Két.
High-Altitude Battle: In World , Rupph vs Két takes place in the sky so that stray attacks won't hit Cendar and Yamaha while they're fighting.
How Do I Shot Web?: Played with- Két notes that when her form changes, she gains the abilities of whatever form she's in. The problem is that she has no idea how to use them. However, she also retains her normal powers, so she often doesn't bother with the new ones.
This becomes a problem, however, when she's inhabiting Link, and has no idea how his abilities work or how she's supposed to use them, since she can't use her own in his body.
Hypocritical Humor: Phantom Thief Kiara's impostor, a thief, gets upset when the real thing shows up and steals the gem that said impostor stole.
Lame Pun Reaction: Niv hits Két with a speech bubble after the latter, a cat, says she's going to take a catnap.
It later gets reversed when, after Két hits Blair with a speech bubble and scolds him on his behavior, he says that her words "hurt him so." Két immediately calls Niv out on it, and she whines that she honestly didn't intend for that to happen.
Lampshade Hanging: Két frequently does this in regards to elements of the comic and silly developments.
Large Ham: Silverado has these tendencies, especially when he's showing off.
Morphic Resonance: On Pop Star, Két becomes a Gaw Gaw, but still has her fur colors, fur pattern, and bow. Which allows Meta Knight to recognize that she's not from their universe in the first place. This turns out to be a recurring thing, as when she goes to the Digital World, she turns into a Gatomon, again retaining her fur color, pattern, and bow.
Damaru and Silverado seem to undergo this too, but only if it's absolutely necessary for them to blend in on a particular world, as evidenced by them remaining normal in the Digital World but being changed while on Pop Star.
Mr. Exposition: Niv is this at the beginning of the comic, to explain the basic plot and how Két's world-traveling will work.
Damaru becomes this in World  when it comes to dimensional hijinks. Later, he explains to Blair why he's going after Két and how he and Silverado wound up together. The latter ends up becoming a flashback.
The Multiverse: The story takes place in one of these. Niv explains that there are dimensional barriers between universes, or "worlds", but they are fragile due to the Goddess of Destruction throwing the Scarf of Destruction through them.
Murder the Hypotenuse: When Blair (wrongly) determines that Aqua is trying to steal Két (who is not interested) away from him, he decides that this is the obvious solution.
The Napoleon: Damaru had this problem in the past, due to looking like a ten year old despite being 50.
Ninja Prop: Két periodically uses speech bubbles as weapons or shields. This tends to confuse the people around her, so she only does it if she feels she needs to use her wall-powers to win a fight.
No Fourth Wall: Only in application to Két- she's perfectly aware of the fact that she's in a comic and is constantly looking at elements of the comic (such as speech bubbles and world boxes) to get information. However, everyone else- sans Niv, who is the Author Avatar- is unaware of the fourth wall.
No Indoor Voice: Damaru's Digivice is at such a high volume that Két has to cover her ears constantly when they're interacting with it. It's implied that this is because Damaru accidentally turned the volume on it up, though.
Noodle Incident: Silverado somehow managed to insult an entire village with one sentence.
Offscreen Teleportation: If the focus isn't on her, Két might as well not be there- a fact which she is very much aware of and isn't afraid to take advantage of, either to run away or give her the edge in a fight.
Oh, Crap: Két has one here. It tuns out to be because Blair is in the comic.
And then another one when she first lands in World [O]. It's because Silvena's there, and Silvena seeks to make Két's body her own.
When she's finally safe and sound in World , Niv reveals the message she was trying to deliver but Két was refusing to listen to while in World [O] - Silvena has the scarf.
Rapid Aging: While we don't get to see it, Damau explains that this is why he looks 20 years old instead of the 10 he did before on this page.
Reading Ahead in the Script: Done in reverse - due to the Web Comic format, Két can't read ahead. However, she can read back and look at updates she's not in to get an idea of what's going on. This comes in handy when she's absent for 40 pages.
Rugged Scar: Két has several, though at first the only one we can see is the one on her left hand. When she's turned into a Gatomon, she's revealed to have one on her chest, and when she gets a sleeveless shirt in World , another two are revealed - a larger one on her left arm and a small one on her right arm at around her elbow.
Scars Are Forever: Két has several scars that, while she doesn't necessarily make an active effort to hide, she doesn't really show off, either. She flat-out states in this page that several of them are from her first encounter with Blair.
Screw This, I'm Outta Here!: Silverado wisely dispels himself when Blair insists on having a sparring match against Damaru. Két later pulls it when Aqua confronts Blair, leaving a sign that says "Dude, you're on your own."
Separate Scene Storytelling: Két tricks Twisted!Glandor into telling her about why he wears a cloak with one of these. She uses the fact that she's off-panel during it to run away.
Sliding Scale of Fourth Wall Hardness: Varies based on who's around. When Két and Niv are talking it's at its softest, Két on her own is a bit harder, and when Két's not around there isn't much in the way of wall-breaking at all.
Smurfing: Niv's "What the fluff?!" and Silverado replacing most swear words with some variation of 'Squawk'.
Technicolor Eyes: Since Aware is highly based in fantasy, several characters have oddly colored eyes, such as Damaru who has Purple Eyes and Blair who has pink eyes. In fact, Két herself appears to be an odd one out amongst the main cast, as she simply has blue eyes. Niv having brown eyes is an exception due to her being an Author Avatar.
Telepathy: Glandor has it. Két seems to be immune to it, though she's not entirely sure why so it's likely because of some outside source.
Tempting Fate: Despite her genre-savviness, there are times when Két tempts fate due to frustration or annoyance. Niv lampshades that she should really know better.
Muddy does it when Két agrees to escort him on Starlo. Damaru's first official appearance happens three comics later.
Thinking Out Loud: Két is prone to doing this, especially when something catches her off guard. While in World , Meta Knight catches her doing this, and informs her that it'd be better for her not to voice her thoughts if she wants to keep a low profile. She's notably more self-conscious about talking to Niv through thought after this, though she still does slip up.
This Is Gonna Suck: Két's reaction to the fact that Damaru has become her Digidestined in World .
Translation Punctuation: Any language is translated with the use of value signs (<Like so>) with a note about what it's translated from. This allows Két to essentially understand any language, and even speak it if she puts her own text into brackets.
Trigger Happy: Damaru's standard solution to most problems is to shoot them. Preferably in the face.
Unconventional Formatting: Some characters use different fonts to emphasize that there's something different about them. Rupph, who is made of data, begins all of her speech bubbles with a ">" and uses a more formal font. Various robotic characters and devices will use a more mechanical font. Niv's narration bubbles use the Courier font, despite that her speech bubbles are normal, to indicate that she's sending them VIA computer messages. Silvena also uses a different font, perhaps to emphasize her more supernatural nature. Phantom Thief Kiara has a different font as well. She does it intentionally to disguise her voice.
Unsound Effect: Some of the sound effects are somewhat... nonstandard. Highlights include "lands", "sword noise", and "offscreen crash".
Wrong Context Magic: Két retains her wall-awareness and her aerokinesis no matter what world she's on. This gives her an explicit advantage in places like the Digital World, where her aerokinesis gave her the edge over an Ultimate level Digimon - an opponent that an ordinary Gatomon, whose form she'd taken to fit in, would have a lot of difficulty fighting.
Yandere: Blair is a male example. He's generally affable... until you either get on his bad side or get between him and Két. Then the reason for his nickname of "Psychotic" becomes all too apparent.
Ye Olde Butcherede Englishe: Silvena speaks like this. It could be because she's from a Twisted world, or because she originates from many years in the past... but since Silverado has at least one of these things going for him, it's likely just her being dramatic.
