AWKWARD ZOMBIE

Heaven Sealed
Athos gives Eliwood Heaven Seal when he is about to promote.
Eliwood then says the seals don't find him worthy, whilst holding onto the seal.
Suddenly, the heaven seal magically turns into a full size horse (still in Eliwood's hand), which crushes Eliwood under its weight.

Evasive Maneuvers
Lord (Lyn or Eirika or someone weak like that) is hit by a gigantic axe, and runs to the throne for safety.Then the lord somehow has an easier time dodging the same axe while sitting down, immobile, on the throne.

Late Promotion Elimination
Unpromoted or recently promoted Eliwood is having a fierce epic duel with a mercenary or some generic mook. Finally defeats him with maybe the aid of a healer or vulnerary.
"Finally!" Calls to Lyn and Hector that he took care of one of the enemy, and looks to see Blade Lord Lyn and Great Lord Hector surrounded by piles of defeated enemies.

Mario Mario:
Mario, Peach, Toad and Luigi run through a course with Double Cherries. Luigi and a bunch of clones get taken out. Mario, his clone, Peach and Toad all make it through to the end of the course. Nobody notices the switch.

Mario Two:
Mario sees one of his clones get shot down and mourns him, thinking it was Luigi while Luigi stands in the background.

Rabbit Run/Nationally Graphic:
Mario and the gang chase after rabbits, but can't quite catch them. Luigi runs past them in the Cat Suit and pounces on the rabbit.
PEACH: "Hooray!!"
Toad, Mario, and Peach's faces turn aghast as the see Luigi feasting on the rabbit. Possible alternate delivery has them each trying a different powerup to catch the rabbit, Fire Flower, Boomerang, etc, before Luigi manages it.

Taste the Rainbow:
Mario eats a red mushroom. Eats a green mushroom. Looks over at Blue Toad and sees a flavor he hasn't tried yet. Licks the back of his head. Whistles innocently.

Dead Arm

OoT Link has just finished killing a gold skullita, and the token spawns just above his head, in arms reach.

Link: Welp. I guess I can't get it.

Navi: Why can't you just reach for it?

Link tries to stretch his body.

Navi: I meant with your arms.

Link bursts out laughing.

Link: Pfft. EVERYONE knows that arms are for holding and throwing stuff.

Panel zooms out to show Link encumbered with a great deal of objects.

Wario-torn Veteran
Smash Tips!
Tip: Wario can even eat explosives. It'll damage nearby characters, too!
Wario is calling out to Pit. "Hey bird kid!"
Pit is watching with a worried look. Wario is holding an explosive crate over his gaping maw. "Watch this!"
Cut to Pit lying on a psychologist's couch as Dr Mario is taking notes.
Pit: "I still remember every detail. I could have stopped him!"

I See Hot/Equivalent Exchange/Nth Law of Thermodynamics/Thermoballistic:
Trainer Katie tells an Ice Type Pokemon to use Blizzard. Pokemon obliges and shoots cold air out of its mouth.
KATIE: "Wait...that violates the basic tenets of thermodynamics. Where does the heat go?"
Katie gets engulfed in a flaming fart.

Director's Paper Cut:
Mr. Game and Watch encounters Master Hand. Master Hand forcefully points his finger at him to attack. Last panel is M. Hand inside Dr. Mario's office with an enormous paper cut. Dr. Mario bandages it up.
"Do I get paid extra for thi-"
"NO"

It'd be funny to see Master Hand interacting with the characters in some way that places one above him for a moment.

Survival of the Fattest:
Wii Fit Trainer is hopping around apartment on one foot when she sees an extremely obese Kirby sitting on the couch and eating the contents of several party balls and spitting out Bob-omb keys.
WII FIT TRAINER: "What are you doing? You can't pig out like this all day and expect to be in fighting shape!"
KIRBY: "Actually, this helps me fight better."
"I've kind of had it with being one of the lightest characters in the game so I'm trying to get heavier and harder to launch."
Wii Fit Trainer stares at Kirby for a moment in disbelief.
Comic ends with Marth walking inside the apartment and seeing an extremely obese Wii Fit trainer eating with Kirby.

Wait, can Kirby even talk? Maybe DeeDeeDee or Metaknight should tell her that.

Creative Exodus
Cpt. Falcon complains about Exodus, Samus blames herself. Cap jokingly reminds her that Ridley Scott is a human, and Samus insists that he's a bypruduct of the Space Pirates cloning a new Ridley every time she kills him.
The final panel is Ridley and Ridley Scott in matching outfits walking down the road like Danny DeVito and Arnold Imnotspellingthat in 'Twins'.

By "her", he meant Wii Fit Trainer.

Custom Dodo/Robot Nicks/Aahhhhh!gment/Augmentatious/In Hand's Mitts:
The Smash Cast sits around and discusses the new stuff.
SAMUS: "Well, trophies, stickers, coins what else could he have in store?"
LUIGI: "Pogs?"
PIT: "Costumes?"
C. FALCON: "Race cars?!"
Samus rolls her eyes at the suggestion. Master Hand makes his appearance.
MASTER HAND: "And now our newest collectible to fight over...*drum roll*..."
Master Hand opens his...ummm...hand to display the Custom Setting Bags.
MASTER HAND: "...Customizations!!!"
SAMUS: "Neat."
Master Hand pulls back a curtain where Crazy Hand and Dr. Mario await with tools and a surgical table.
MASTER HAND: "Whoooooooo's first!?"
Master Hand holds a large drill.

Heavy is the Head/Mushy:
Mario, Luigi, Peach, and Toad make it to the flag and argue over who gets the crown. Each grabbing it and putting it on.
MARIO: "Do you really need two crowns?"
PEACH: "Your name is in the title!!"
LUIGI: "Year of Luigi. Jus' sayin'."
TOAD: "Well, I never get to wear a hat..."
MARIO: "What do you mean? You're wearing one right..."
Mario pokes Toad's "cap". It throbs.
MARIO: "You keep it."

I have a feeling that my ideas are becoming less like parody comics and more like SSB4 sitcoms.
