Koopa Paratroopa made their debut in Super Mario Bros. as a winged variation of the Koopa Troopa, and has become a common enemy in later Mario games. Like their regular variations, the Koopa Paratroopas are commonly seen in their green and red variations. The green Paratroopas either fly back and forth in a fixed path or hop around, while red Paratroopas fly up and down. If a Koopa Paratroopa is jumped on, they will lose their wings, turning them into regular Koopa Troopas.
Koopa Paratroopas are often found flying in midair. Dealing enough damage by attacking them or jumping on them will make them lose their wings, turning them into regular Koopa Troopas. Similar to the Koopa Troopas, the Paratroopas can be defeated by grabbing and throwing the Koopa Troopa inside its shell, or by knocking it off a ledge, which will result in a Paratroopa KO bonus where the player receives 300 points for each Paratroopa KO'd.
While the green Koopa Paratroopas are common, only one red Koopa Paratroopa appears in the entire stage right before the battle with the Yoshi Team. The red Paratroopa's shell behave similarly to their green variation during the stage, but it also deals flame damage.
As an enemy
Koopa Paratroopas appear as enemies in The Subspace Emissary. The green and red versions appear as flying enemies in stages where Bowser's minions are present. Similar to their Melee counterparts, if a Koopa Paratroopa is jumped on, they will lose their wings, turning them into regular Koopa Troopas; however, they cannot harm players on contact, but they attack with a swooping headbutt. Some of the red Koopa Paratroopas even chase their targets and strike when they get close.
When a Koopa Paratroopa loses their wings and fall (provided the attack caused them to flinch), they act similarly to a regular Koopa Troopa. Their health bar, however, will still read "Paratroopa". The wingless red Paratroopas follow their target on foot, though they're slow and easy to escape from. After a while, if not destroyed, they can grow back wings when they go off-screen. If the Paratroopa is KO'd with one hit and doesn't lose its wings, it will reel normally like a defeated enemy instead retreating into its shell.
It is somewhat difficult to catch the Paratroopas as trophies using a Trophy Stand, since a single hit may remove their wings and turn them into a regular Koopa. The player can damage them, move away from them until they aren't visible, and return to their position, making their wings return.
The Koopa Paratroopa trophies can be obtained by using the Trophy Stand on the Green and Red Koopa Paratroopas in The Subspace Emissary. The Green Koopa Paratroopa trophy states that it appears in Mario Hoops 3-on-3, however only the Red Koopa Paratroopa appears in that game.
As an enemy
The Koopa Pararoopas appear as enemies in Smash Run, reprising their behavior from Brawl.
Koopa Paratroopas also appear as part of the Mario-themed Vs. Enemy Team final battle.
The Green Koopa Paratroopa is exclusive to Super Smash Bros. for Nintendo 3DS. The Red Koopa Paratroopa appears in both versions. In Super Smash Bros. for Wii U, it is part of the Bowser's Minions Trophy Box.
