Koopa Troopas (commonly shortened to Koopas or sometimes Troopas) are anthropomorphic, turtle-like creatures with removable shells that come in many different colors, with red and green Koopa Troopas being the most common; green Koopa Troopas usually walk back and forth without any concerns for pits or other obstacles, and red Koopa Troopas usually walk back and forth without falling off of their platforms. Koopa Troopas are usually displayed as foot soldiers of the Koopa Troop, under the direct leadership of Bowser. Since Super Mario 64, however, not all Koopa Troopas work for Bowser (or any other villain), some of whom even act as allies to Mario during his adventures, and have appeared as playable characters in various spin-off games starting with Super Mario Kart. They are notable for the many uses of their shells in the Super Mario franchise.
An enemy that first appeared in Mario Bros., the Shellcreeper, was the "ancestor" of the Koopa Troopa. When creating Super Mario Bros., a few changes were made to the enemies, including the ability to jump on them in order to damage them.
The Koopa Troopa's Japanese name,「ノコノコ」(Nokonoko), is a Japanese term meaning "to walk unconcernedly", describing the green-shelled Koopa Troopas' behavior. The English name comes from Bowser's Japanese name,「クッパ」(Kuppa), which is itself derived from the Korean dish of the same name, while "Troopa" is a corruption of the word "trooper", seemingly to keep the reference to forward marching from the Japanese name intact.
It is worth noting that the Koopa Troopas' ability to remove their shells is not true to any type of turtle, although popular culture often overlooks this fact.
Koopa Troopas are tortoise-like creatures with removable shells. In general, they have basic appearances compared to other Koopa species. They have elliptical beady eyes, large beak-like noses, short limbs, and large heads. Their hands have four pointed/triangular-shaped digits (excluding artwork from Super Mario World 2: Yoshi's Island and its remake, and the Paper Mario series where in-game their fingers are not) and have three pointed toes on their flat-soled feet, which, unlike other Koopa species, have no pads at all. In earlier games, Koopa Troopas were quadrupedal (walking on four legs), had flatter noses, and detailed leg joints. Starting from Super Mario World onwards, they now stand on two legs, have more rounded noses, and wear shoes with beige soles that often match the color of the shells they wear (in the Super Mario Galaxy series, however, they revert back to walking on four legs, having four toes on their back legs and being barefooted). Having beaks, Koopa Troopas have no teeth compared to other species, but may be drawn with them for expression purposes (although their conceptual ancestor, Shellcreepers, have them).
Koopa Troopas generally have yellow scales, but in earlier games had orange. Some Koopa Troopas can have olive green, peach and even cyan scales. In Super Mario Strikers, the color of their scales change depending on with team they were on: salmon for Mario's, chalky yellow for Luigi's, peach for Waluigi's, and orange for Daisy's. In Super Mario Party, Red Koopa Troopas' scales have an orange tint from the playable Koopa Troopa.

A Koopa Troopa's shell consists of a carapace with colored, hexagon-shaped scutes in a pattern on the top, with smaller, triangular ones at the edges, with dark flesh underneath that appear as "grooves"; a beige colored plaston with several "ribs" on its surface and six holes on it where the Koopa Troopa's head, arms, legs, and tail emerge from; all joined by a white bridge that follows along the perimeter of the shell and rises at the spots where the Koopa Troopa's head and tail are. The most common color for a Koopa Troopa's shell is green, with red being the second. However, there have also been less common colors such as blue, yellow, light-blue, light-green, dark-green, orange, purple, black, and, on rare occasions, gold. Despite having large heads, Koopa Troopas can pull them into their shells with little effort. In Puzzle & Dragons: Super Mario Bros. Edition, Mario Kart 8, and Mario Kart Tour, a Koopa Troopa can withdraw into its shell and pop back out in mid-air. Underneath their shells, they wear white undershirts (in Super Mario 64 and its remake Super Mario 64 DS, they also wear pink or blue shorts, respectively) and have round bodies.
From Super Mario 64 onwards, Koopa Troopas have been given voices created electronically, starting with whooping sounds (which were also shared with Goombas, Grand Goombas and the Big Bob-omb, with varying speeds, until the sounds were exclusive to Koopa Troopas in later games), then other noises such as wheezing, clucking, and gurgling. In Mario Kart 8, they were also given high-pitched whistling sounds whenever performing an antigravity trick or placing first.

In Illumination's The Super Mario Bros. Movie, Koopa Troopas are slimmer than before, have teeth, have perfectly round heads elevated above their brown eyes, wear socks and usually have helmets. They are also shown to be wearing accessories, to distinguish from each other; for example, one Koopa Troopa wears spiked shoulder pads and an eyepatch, and another wears a Spiny Shell as its shell and helmet. In addition, unlike their previous appearances, they wield various weapons such as spears and hammers.
Green Koopa Troopas are specifically given an association with water in games such as Mario Power Tennis and Puzzles and Dragons: Super Mario Bros. Edition, since their Offensive and Defensive Power Shots in the former game involve water, and in the latter game their attribute is Water. In Puzzles and Dragons: Super Mario Bros. Edition, Red Koopa Troopas have fire as their attribute, while Yellow Koopa Troopas have light.
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.
