Scribblenauts has quite a large cast of characters to summon. Now let's write, "T-V T-R-O-P-E-S C-H-A-R-A-C-T-E-R P-A-G-E".
Maxwell
- Batman Can Breathe in Space: Unlike the astronauts of the series, he is perfectly fine when traveling to other planets, and does not need any special equipment.
- Character Development: Unmasked shows that he learned his lesson from Unlimited (storywise at least, there's probably nothing stopping the player from being a jerkass).
- Child Soldiers: He has been sent to war several times.
- Clothes Make the Superman: In Unmasked, he can gain the abilities of DC heroes or villains by wearing their costumes. For instance, wearing the Superman costume grants him flight, increased strength, speed, and durability, and the ability to shoot Eye Beams.
- Cutscene Incompetence: In normal gameplay, Maxwell is pretty much unstoppable. In story sequences, especially in Unmasked, either his notebook's power is severely nerfed or he just doesn't think of any of the countless ways he could instantly solve every problem.
- Determinator: In Unlimited, nothing will stop him from rescuing Lily from the Taken for Granite curse.
- Fragile Speedster: In the first game, Maxwell moves extremely fast, but he's only able to take twice as many hits as an ordinary human.
- Indy Ploy: Invoked by the notebook: Maxwell will use literally whatever is at hand.
- Instant Expert: Unless there is a plot-related purpose for it not to work, Maxwell can use any item that has a function. Anything he spawns will be usable.
- Jerk with a Heart of Gold: Maxwell usually doesn't get much in terms of characterization, but the plot of Scribblenauts Unlimited is kicked off when he plays a trick on a hungry beggar and conjures him a rotten apple, and he spends the rest of the game trying to make amends.
- Kid Hero: Maxwell is a child, one of the youngest of his family.
- Mad Scientist: In one level, he decides to make a zombie out of random body parts.
- Master of Disguise: He has a variety of disguises, using both avatars and items.
- Noodle Implements: Write ANYTHING. Chances are he can use it.
- Pop-Cultured Badass: The Unmasked comic book series reveals him to be one.
- Reality Warper: Thanks to his magical notebook, he has godlike power.
- Red Is Heroic: He always wears his red rooster helmet.
- Signature Headgear: Never seen without his rooster helmet; a red hat with three horns. In Unlimited, it's revealed that his family has their rooster hat as well.
- Suddenly Voiced: He's a Heroic Mime in the first three games. Come Unmasked he suddenly starts talking to other characters.
- Took a Level in Badass: In the second game, he gained the power to use adjectives, becoming even stronger than before. He also got numerous other abilities, such as unlimited ammo. Then, Unlimited gave him the ability to create his own custom objects and apply adjectives to himself, making him nearly unstoppable. Finally, in Unmasked, his health was vastly increased, he gained the ability to fight bare-handed (though it's a weak method of attacking unless boosted with adjectives or costumes), and could wear costumes to further his strength, at the cost of unlimited ammo and the ability to use extremely powerful adjectives or repeat words without punishment.
- "Well Done, Son" Guy: If Unmasked is anything to go by, Maxwell has a fear of not being as good as his dad.
Doppelganger/Alexander
Maxwell's evil twin, who also wields a Scribblenaut notebook. Rather than using it to help people like Maxwell, he uses it to cause chaos and destruction.
- Ascended Extra: From one-off appearance to Final Boss in the first two games...
- Demoted to Extra: ...Only to get just one "canon" appearance in Unlimited in the Big Boo's Haunt level. And it's in a starite shard mission, too, and not one for a full starite. Un-demoted in Scribblenauts Unmasked, where he's The Heavy.
- Dropped a Bridge on Him
- Evil Twin
- Final Boss: Of Super Scribblenauts.
- Happily Adopted: It is revealed in the Unmasked spin-off comic he was adopted by Maxwell's parents and even gets his own name: Alexander, after Alexander the Great.
- The Heavy: In Scribblenauts Unmasked.
- Heel–Face Turn: At the end of Scribblenauts Unmasked.
- Killed Off for Real: At the end of Super Scribblenauts. Maxwell can't even use potions to bring him back. He's summonable in Unlimited, however. In addition, he returns as an antagonist in Unmasked. This potentially indicates that Super Scribblenauts takes place after Unmasked, granted that Doppelganger's Heel–Face Turn didn't stick.
- Palette Swap: Of Maxwell.
- Sdrawkcab Name: Averted. Of all the possible synonyms for summoning him, typing this in just spawns a cartridge.
- Slasher Smile
- Weak, but Skilled: In Scribblenauts Unmasked, he said that his powers are relatively limited, his notebook being only limited to the single page that Maxwell created him from. He still poses quite a legitimate threat though.
Lily
Maxwell's twin sister who first appears in Scribblenauts Unlimited.
- Aesop Collateral Damage: Gets turned to stone as a punishment for Maxwell giving the old man a rotten apple. Granted, she DID seem to find the idea amusing as well.
- Distaff Counterpart: Of Maxwell.
- Fangirl: Appears to be one for Batman, as she's asking for his autograph in Scribblenauts Unmasked.
- Narrator: In Scribblenauts Unlimited, she is explaining the story of Maxwell.
- Pink Means Feminine: She's female and wears a pink rooster hat, unlike her other male siblings.
- Taken for Granite: She gets turned to stone in Scribblenauts Unlimited, so Maxwell needs to use the starites to heal her.
- Teleportation: Her globe lets her teleport anywhere she wants.
- Why Did It Have to Be Snakes?: In Unlimited, nothing Maxwell summons can faze Lily...unless it's Medusa or a similar creature that causes petrification.
Jeremiah Slaczka
The president of 5th Cell.
- Creator Cameo
- Distressed Dude: He gets kidnapped by Doppelganger in Super Scribblenauts.
- Dropped a Bridge on Him: He was in Doppelganger's spaceship when it exploded.
- Happily Married: With his wife, Kari.
- Took a Level in Badass: Once an ordinary man, he becomes one of the most powerful characters in Unmasked, having strength and durability that can rival that of Parallax.

Nathan Hernandez
A man in Stormtrooper armor who was an animator for the game.- Creator Cameo
- Mighty Glacier: Deals huge amounts of damage per hit and has vast amounts of health, but he moves at about the same speed as a normal human.

A T. rex who wears a Ryu-esque bandana who was an artist for the game.- Ax-Crazy: Spawns hostile, unless modified to have the "friendly" adjective or a similar one.
- Kamehame Hadoken: Fittingly for the Ryu reference, Edy can shoot fireballs at any NPC too big for him to just eat. In Unlimited, this was changed to a three-round burst of purple orb projectiles.
- One-Hit Kill: Eating you.

- Stone Wall: Is fairly durable, but has slow attacks that don't do much damage.
- Villain Decay: One of the trailers for Unlimited shows him being dressed as a clown for a party.
