Chain-Link

A Chain-Link, also known as a fence, Chain Link Fence, wire net, or metal screen, is an object found in various Mario games. The player character can climb along the surface of the fence and punch it to defeat enemies on the other side. In some games, there are panels that can be used to flip the character to the other side. Similar climbable meshes of vines and other interlocking materials appear in Wario Land 3.

Super Mario World
In Super Mario World, fences occasionally appear in castles. Mario or Luigi can jump on, climb on, and jump off fences to go around traps such as lava. The brothers can also flip to the other side by punching a square panel. Climbing Koopas are commonly found to be climbing on fences, and they are capable of climbing around both sides of a fence. The brothers may punch the climbing Koopas that are on the other side to defeat them.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64 and Super Mario 64 DS, wire nets have different designs depending on the location and have multiple purposes depending on the contexts. Some of them, found primarily in the Hazy Maze Cave, in Bowser in the Fire Sea, and on Tiny-Huge Island, can be climbed, but only horizontally instead of vertically. Others are instead used as walls that only Vanish Mario can get through, which is used more commonly. Sometimes, this is needed to collect a Power Star, while other times (particularly in the remake), it is simply a shortcut (such as in Express Elevator--Hurry Up!). Certain brick walls in Wet-Dry World's downtown work the same way. Sometimes, vertical or block-shaped ones are not found near a Vanish Cap (or Power Flower in the remake) and, as such, are simply used as walls or platforms. This type appears heavily in the Hazy Maze Cave; Dire, Dire Docks; and Tick Tock Clock.

Super Mario Sunshine
In Super Mario Sunshine, metal screens can be climbed in both horizontal and vertical orientations. Many of the metal screens take the form of boxes which enclose enemies and coins, although some are traditionally flat. Metal screens appear in Ricco Harbor, Pinna Park, and Pianta Village and can be used to knock off enemies from the other side. The game also introduces Moving Fences.

New Super Mario Bros.
Fences appear again in New Super Mario Bros. in and, being the principal feature of both levels.

New Super Mario Bros. Wii
Fences reappear in New Super Mario Bros. Wii as obstacles in Towers and Castles, similar to Super Mario World. Certain areas are inaccessible unless the player switch to the other side of the fence, via the flip panel. There is also a special type of fence which can be rotated 90 degrees left or right by the first player who climbs the fence by tilting the Wii Remote left or right. Also, a yellow fence is used in the Power-up Panels minigame.

New Super Mario Bros. 2
Fences also reappear in New Super Mario Bros. 2, along with other special types of fences introduced in the game. In, there are large fences made up of smaller fences that move upwards along with the rising lava and, at certain points, rotate. They are required to progress through most of the level. In World 5-Castle, Moving Fences move along a track, and can be changed to move above or below the wire by pressing /. The flip panels are absent.

New Super Mario Bros. U
Fences appear once again in the Wii U game New Super Mario Bros. U with the same design as in Super Mario World, with red borders instead of gray. Unlike in other games, however, the player cannot punch on the fences. The flip panels are absent once more.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
Chain-Links (parsed Chain Links in the Prima guide and Chainlinks in the PAL release) appear in Super Mario 3D World and Super Mario 3D World + Bowser's Fury in several stages as either stationary walls or platforms or moving along tracks as obstacles. In this game, they cannot be climbed on unless the character assumes the Cat form, but can otherwise simply be used to wall jump.

Super Mario Maker 2
Chain-Links with platforms on top of them appear in Super Mario Maker 2 in several themes (except ground, ghost house, and desert) in the Super Mario 3D World style as the style's Semisolid Platforms, all of which Cat Mario can climb up, regardless of theme. Unlike in Super Mario 3D World, they can be climbed indefinitely without falling off.

Super Mario World television series
A small fence makes a brief appearance as an obstacle in Neon Castle in the Super Mario World episode "Mama Luigi". Mario, Luigi and Yoshi are able to easily pass this fence by simply using its revolving gate.

Paper Mario
Wire nets make a brief appearance in Paper Mario, where they are found in a Conveyor Belt-filled segment of Shy Guy's Toy Box and have a similar function to their appearance in Super Mario 64. To get past them, Mario needs to use Lady Bow's Outta Sight ability while on a Conveyor Belt.

Mario Kart series
Platforms made of Chain-Links, known as Kanaami Roads, appear in some courses in the Mario Kart series starting with Mario Kart: Super Circuit.

Mario Party 9
In Mario Party 9, a fence appears in the Bowser Jr. minigame Cage Match. Fences are used in the same way as in New Super Mario Bros. Wii.

Mario Party: Island Tour
In Mario Party: Island Tour, fences appear as floor during one segment of Gyro for the Gold.

Super Mario Party
In Super Mario Party, a climbable fence appears prominently in Drop Shot.
