Summit (頂上 Chôjô) is a stage in Super Smash Bros. Brawl. It starts on an icy mountain top which Masahiro Sakurai, the director, describes as being the summit of Icicle Mountain, a stage that appears in Super Smash Bros. Melee. The stage was revealed on Smash Bros. DOJO!! on October 31, 2007. In reference to Halloween, one image featured a pumpkin.
 Stage description
The mountain has several linear platforms on the top, and the leftmost can be unhinged, temporarily disabling it. There is a blue sloped platform of ice to the right, which can be broken, as well as a small "cave" at the bottom, with an icicle occasionally falling, causing high knockback and damage. When not surrounded by water, a cloud platform will occasionally pass by, which players can stand on. An important thing to remember is that the edges of the bottom of the stage cannot be grabbed, as they are made of ice. Naturally, the floor is extremely slippery, especially when a character attempts to change direction rapidly. The Ice Climbers are the only characters who can walk normally on the stage without sliding.
Several vegetables from the original Ice Climber will make an appearance acting as Food Items. The vegetables appear in the order they do in the original game, namely an eggplant, carrot, cabbage, cucumber, corn, turnip, pumpkin, Chinese cabbage, potato, and a mushroom. They all restore 5% of health with the exception of the corn, which restores 10%. They will not appear if Food is turned off or item frequency is set to none.
The stage begins on top of the mountain but quickly breaks to the point where it begins to slide down a hill. During the descent, everybody becomes much more floaty. The key factor to survival is to remain on the iceberg, as making contact with the left side of the mountain will result in high knockback and damage, and contact with the ground to the right of the peak will result in the player getting carried away to the right blastline and being KO'ed. Fortunately, it's possible to jump off of the ground in spite of its speed, but this must be done very quickly. Eventually, the peak splashes into water, reducing the possibility of getting KO'd on the bottom blastlines; however, the water is also where the Fish (see below) lives, and players who fall in the water must quickly leave as to avoid getting KO'd by the Fish. Little segments of ice will also float by in the water, standing on these can help avoid the Fish. As time progresses, the stage eventually sinks, due to extreme weight from the Polar Bear in the background. After a while, the iceberg flies back up to the top of the mountain and the whole process is repeated.
 The Fish
The Fish is a hazard on the Summit. In Super Smash Bros. Brawl, the fish will pop out of the sea to eat any character that stays in the water at the bottom of the stage for too long. The fish will only appear when there is water around the base of the stage, not when the stage is at the top of the mountain or falling/rising. If the fish swallows a character, that character will be carried through the lower blast line and KOed. The fish's tail is also capable of hurting characters, dealing 15% damage and giving significant vertical knockback. The fish can eat any number of characters in a single appearance, but it will always follow a set arc and will go after whichever character has been in the water the longest. If swallowed, there is no way to escape, but there is a small window of time in which a character can get out of the fish's path.
 Tournament Legality
This stage is banned in tournaments, due to ungrabbable edges, slippery surfaces, and powerful camping spots at the bottom of the stage, as well as the Fish stage hazard. Also, the blue ice platform and the leftmost platform allow for wall infinites.
While this stage doesn't come directly from Ice Climber there are elements in this stage that do come from Ice Climber. In Ice Climber their points in the game where the player has to jump on clouds that move across the stage and act as a moving platform. The first part of this stage features a cloud that floats by and acts as a moving platform. One of the enemies in Ice Climber are Polar Bears. If a player takes too long to beat a level the Polar Bear would appear and jump to make the screen scroll up. In this stage when the stage is in the water a Polar Bear can be seen in the background. The Polar Bear jumps and makes the stage go deeper in the water. In the later levels of Ice Climber there would be icicles that start forming and dropping on the player. If the player gets hit by the icicles the player would lose a life. The icicles that form and drop are retained on this stage. If the player wants to get bonuses at the end of each level in Ice Climber the player has to get all the vegetables near the top of the mountain and complete the level within a set forty second time limit. The vegetables that are shown for each level are eggplants, carrots, cabbages, cucumbers, corn, turnips, pumpkins, Chinese cabbages, potatos, and mushrooms. In this stage these vegetables can appear and can be eaten to lower the player's damage.
In Balloon Fight there is a giant fish that can eat the players or the enemies if they get too close to the water or if they fall in the water after all the balloons have been popped. This giant fish can be seen in this stage when the player gets to the edge of the stage or when the player jumps in the water. If the player doesn't get out of the way in time the fish would jump out of the water and eat the player.
