The Koopa Troopa (ノコノコ, Noko Noko) is a common enemy from the Mario universe which appears in Super Smash Bros. Melee and Brawl. It appears in both green and red variations, as a common unit of the Koopa Troop.
 In Super Smash Bros.
Two Green Koopa Troopas resembling their Super Mario Bros. 8-bit sprites walk back and forth in the background of the Mushroom Kingdom stage.
Green and red Koopa Troopas make an appearance in the first stage of Adventure Mode, where they walk back and forth. If the player makes contact with them, they will take damage. Damage and knockback varies on any difficulties. On very hard difficulty, if the player makes contact with them, they will take 40% damage with very powerful horizontal knockback, KO'ing the player almost at any percent. Simply attacking them makes them retreat into their shells. The player can pick up their shells and use them like the Green Shell item. Even if the shell is red from a red Koopa Troopa, it will function like a regular Green Shell, but also cause a fiery effect. The only difference is that the shells from the Koopa enemy don't disappear. The reason is after a short amount of time Koopa will come back out of its shell and walk back and forth again. This can happen even when the player is holding the shell. To permanently get rid of them, the player must throw them by picking them up with the "Z" button. The player can throw them at their opponents to give them a good amount of damage and sometimes even defeating them at low percentages.
Their stance they take in Melee is a crouching but walking on two legs, which is a mix between the original which they walked on all fours, and Super Mario World, which they had walked upright. Also, one 8-bit green Koopa Troopa cameos in the background of the Mushroom Kingdom stage.
 Trophy Description
Common soldiers in Bowser's army, Koopa Troopas can retreat into their shells. Unbelievable as it may seem, they're clearly unaware of being kicked and sent sliding when in this position. There are many Koopa types, each with a different shell color and unique traits. They all wear T-shirts and shorts under their shells.
Koopa Troopas make an appearance in Brawl's Adventure Mode: The Subspace Emissary. The green and red versions appear as ground enemies in stages where Bowser's minions are present. Unlike their Melee counterparts, Koopa Troopas will not harm players that walk into them. Instead, they attack with a leaping headbutt. They are stompable like Goombas, and will gets into it's shell when stomped. The shell can be picked up like a normal shell and used like a normal shell, but Red Shells won't lock on enemies, unlike in Melee.
 Damage taken
 Koopa Troopa (Green) Trophy Description
A henchman of Bowser. In the old days, they'd retreat into their shells for a short while to protect themselves after being stepped on. Recently, however, some have begun to immediately pop back out. You'll often find them marching straight ahead--if the path ends, they'll just march into the abyss. Surely there are no braver turtles to be found.

 Koopa Troopa (Red) Trophy Description
A turtle in the employ of Bowser. Koopas formerly traveled on four legs, but they've recently been spotted strolling on two. This has freed up their hands, allowing them to chase Mario with nets. Their adaptability must make Bowser very happy indeed. Unlike their green-shelled brethren, red ones do about-faces when they run out of road. They're a bright group.
- Super Mario Bros., 1985
Koopa Troopas first appeared in Super Mario Bros., becoming one of the main enemies of the game, along with Goombas. Mario is able to stomp Koopa Troopas into their shells and kick these shells as projectiles. However, the shells can also pose a danger to Mario if they bounce off of a wall. Koopa Troopas have gone on to be recurring enemies and characters throughout the Mario series.
- Green Koopa Troopas always walk off cliffs in sidescrolling Mario games, but in The Subspace Emissary, they don't walk off cliffs.
