I dreamed up some Level 3s forever ago. I don't know how far Mane6 is willing to go on animating and drawing these things out, but it's fun to think of how epic they could be. I had flashes of UMVC3 cinematic supers in my head, though I doubt TFH is gonna go THAT far. Guess we'll see?
Foenum Rodeo - Command grab. Hog ties the opponent with her lasso and does an exaggerated version of her normal throw, where she bucks the tied opponent into the air off her head and back over and over, before leaping up, nabbing the rope in her teeth and flinging them downward, sending them spinning like a top and crashing into the ground hard, causing a crater to form.
Curtain Call - Mid-range ice strike. Freezes the opponent in place as a blizzard forms all around them. Velvet performs a dancing routine, swaying her body and her limbs around, with blasts of the blizzard buffeting the opponent over and over and increasing the size of their ice prison. She finishes with a final epic pirouette and a pose, and the ice prison explodes into shards.
Soul Mates - Shuma-Gorath style install, which is to say she becomes visibly "powered up" and her Heavy attacks are replaced with a quick, unblockable strike that acts like a grab. If the strike connects, she grabs the opponent in one of her signature bone-crushing hugs, yelling out all sorts of crazed things about how she loves them and they'll be together forever, squeezing them over and over and building up damage until she goes too far and they fly out of her legs in an explosion of floof.
Caretaker's Rage - Close-up gaze attack. Pom finally lets anger get the best of her, the opponent left shocked by her change in demeanor, and Pom commands her entire 'horde' to attack. A quick stampede of puppies sends the opponent tumbling, and both the mom and dad dogs perform an exaggerated tag team combo, bouncing the opponent around and eventually leaving them slammed to the ground, as Pom recovers from her anger and immediately begins regretting her command.
Final Ritual - Mid to long range projectile blast, or perhaps a tracking attack from under the opponent (think Dr. Strange's supers in UMVC3). The opponent is trapped in dark magic when hit, as Fred himself rises up and takes hold. Oleander's eyes glow brightly, chanting the incantation, her body and her book raging with magic, horn glowing larger and larger. Fred raises the trapped opponent high into the air, and finally Ole lets loose a doomsday Final Flash/Iron Avenger/Metsu Hadoken blast of energy over the prone opponent for tons of hits, with Ole eventually collapsing forward when the super ends (and recovering in time to get back to normal gameplay).
Ancestor's Fury (or something similar in Chinese to fit the names of her other two supers) - A dashing forward strike that can also be performed in the air. Tian strikes the opponent multple times using swift dashes back and forth, eventually leaving them flopped onto the ground in a heap. Then she flies up into the air above them, yells out some sort of battle cry, and her fiery mane blazes brightly, raging like an inferno and transforming into a giant shape of a dragon's head, which then inhales and breathes a mighty flamethrower downward on the prone opponent for bunches of hits.
I have an active imagination~
