POW Block

A POW Block (occasionally POW and standing for Power Block according to The Super Mario Bros. Super Show!) is a common block in the Mario franchise. In all games they appear in, their effect when thrown to the ground or hit in the air will cause a large earthquake, causing all enemies on screen to get hurt. POW Blocks can be carried and thrown in most games, and some are required for a 100% game completion. Most POW Blocks are a metallic blue, but some POW Blocks are red.

Mario Bros.
The POW Block is an item that first appears in Mario Bros. (the arcade version and its ports; not the Game & Watch version). When hit, it damages all enemies in the screen, but only those that are on the ground. It can be hit a certain number of times before it disappears. Each time it gets hit, it flattens up. In some ports of the game, the POW Block can be picked up. However, throwing the picked up POW block results in it completely disappearing regardless of how many times it was hit before.

Super Mario Bros. 2
The POW Block has the same function in Super Mario Bros. 2 and its remake, Super Mario Advance, as it had in Mario Bros., but it can only be used once as the player has to throw it onto the ground to activate it. A giant version of the POW Block shows up in Super Mario Advance. A Giant POW Block can bounce around the floor, causing multiple tremors, before it disappears. Unlike in Yume Kōjō: Doki Doki Panic and other games, the word "POW" is animated.

New Super Mario Bros. Wii
The POW Block returns in New Super Mario Bros. Wii. As in Super Mario Bros. 2, it can be picked up and carried, and once thrown, it eliminates all the enemies onscreen and also drops all floating coins. The POW Block is also essential in order to collect Star Coins found hidden in some levels.

Description: ''Here's a blast from the past! Hit a POW Block and all coins will fall to the ground for easy pick up. Use this time wisely to collect all the coins you can. Remember that extra coins mean extra lives, so POW Blocks are money in the bank! They can also be really handy in shaking out hidden Star Coins.'' Card Number: 51 (Normal)

New Super Mario Bros. 2
POW Blocks return in New Super Mario Bros. 2, but as a red variation called Red POW Blocks. Unlike the blue type, these POW Blocks cannot be picked up, so they must be activated by hitting them somehow. In addition, they start a chain reaction with one another when activated; while they cannot defeat on-screen enemies out of its range or drop midair coins, their tremors can hit nearby blocks.

POW Blocks appear in New Super Mario Bros. U, behaving the same way just as in New Super Mario Bros. Wii and appearing in blue once again.

POW Blocks also appear in the expansion pack for New Super Mario Bros. U, New Super Luigi U, serving the same purpose as it did in the base game.

Super Mario 3D World
Red POW Blocks from New Super Mario Bros. 2 appear in Super Mario 3D World, which marks their first appearance in a 3D Mario platformer. They act exactly as they did in New Super Mario Bros. 2, releasing short-ranged shock-waves once hit. As in New Super Mario Bros. 2, they can be used to hit and destroy blocks and enemies, but can also reveal the locations of hidden blocks. At the end of World Bowser-Castle, there is a blue Giant POW Block which needs to be hit four times in order to beat Meowser at the end.

The classic blue POW Block also appears in the port of Mario Bros., Luigi Bros., included in Super Mario 3D World.

Special Items based on POW Blocks are most commonly won in Bonus Challenges, where they could be used almost anywhere afterward, being called Anywhere POWs.

Paper Mario series
In the Paper Mario series, the POW Block is a portable item that does two damage to all enemies (but much more in Super Paper Mario if the remote had been shaken with each corresponding prompt). It penetrates defense and makes enemies with shells (such as Koopa Troopas) flip over.

In Paper Mario: The Thousand-Year Door, the POW Block affects all enemies on the screen, including flying enemies and enemies on the ceiling such as Swoopers.

In Super Paper Mario they are used as a portable item. When active, it damages all the enemies currently on screen. In this game, the POW Block may also be used as a recipe ingredient; however, it can only be cooked on its own into a Megaton Dinner. One of the Sammer Guys fought is called Block of Pow.

In Paper Mario: Sticker Star, POW Blocks appear as stickers, taking their design from how they have commonly appeared since Mario Bros.. When used, a POW Block appears, which Mario hits twice to inflict damage to enemies and occasionally inflict the Crumpled status. Unlike the previous iterations, however, the POW block affects only foes on the ground. The sticker also has a Shiny and Flashy POW Block variant, which deal more damage.

In Paper Mario: Color Splash, POW Blocks appear as Battle Cards, with the same behavior as they had in Paper Mario: Sticker Star. POW Blocks also appear outside of battle in Kiwano Temple, where one is used to flip some spikes, and Violet Passage, where they can be hit with a cannonball in order to collect coins.

Mario Power Tennis
POW Blocks make a small appearance in Mario Power Tennis on the Mario Classic Court. A POW Block moves back and forth across the net. If a player hits the ball through it, all enemies become stunned, allowing the player to defeat them by running into them (this counts as one of two hits needed to stun Sidesteppers; Freezies are defeated instantly). POW Blocks cannot hit Fighter Flies when they are airborne though, but they could be defeated if the player hits the POW block at the correct time. After a certain number of hits, it disappears. After a while, it respawns. Stunned enemies who got hit by the POW block resumes walking after a period of time if the player leaves them alone.

Mario Kart Wii
The POW Block is a new item in Mario Kart Wii. It is a rare pull in an Item Box, and players can obtain this item if they are anywhere from 5th to 9th place. When dispatched by a player, all racers ahead of the user finds POW Blocks above their karts. The POW Block makes players spin out in a similar way to that caused by a Banana Peel, except that they lose all of their current items and they come to a complete stop if it hits them. Players will not be affected by the POW Block if the third strike goes off while they are in mid-air. Players can also avoid it by starting a wheelie, or shaking their controller (like doing a jump trick) right when the third strike goes off. By doing this, they still spin out and lose items, but retain their momentum. It is also possible to avoid it by doing a hop right at the third strike but requires perfect timing. When players have a Star, Mega Mushroom, or Bullet Bill activated, they will not get affected by the POW block. The letters, "POW" can be seen as a license plate of all of the cars in Moonview Highway. The POW Block also received a trading card, alongside the other items that appear in the game.

Trading Card Info
Description: "The POW Block isn't a new concept within the Mushroom Kingdom (think Mario Bros.), but it is a brand new item for the Mario Kart series. If you're lucky enough to get this item, activate it and the POW Block appears over the heads of all other racers. When it disappears after about 5 seconds...POW! Everyone (but you) spins out and stops, allowing you to gain some ground."

Game Tip!: "The POWerful effects of this dangerous item can be avoided. The secret is that you have to be off the ground when the POW Block unleashes its power."
