Pokemon Tower Defense Glitches[]
Sunny Day Glitch[]
There is a Glitch on route 1 if Sunny Day is in effect the game will freeze.
Evolution Jump[]
In an earlier version of the game, right after the x2 speed button was added, there was a glitch where Pokémon would evolve two spots higher up the Pokédex instead of one when x2 speed was turned on. For example; a Dratini would evolve into a Dragonite instead of a Dragonair at level 30 and a Magnemite would evolve into a Farfetch'd. Because this is a glitch that has been fixed, higher evolutions that are a lower level are rare and have high trading value.
Evolution Glitch (Hacked Arcade Games only)[]
lf you evolve any Pokémon (except Pidgey), it will say "Bulbasaur evolved into Ivysaur," and will not let you evolve the Pokemon. This has since been patched.
Nasty Plot[]
Another type of glitch is Nasty Plot with Growlithe and Arcanine, where Growlithe and Arcanine could learn Nasty Plot in an earlier version. Again, this was fixed later, so these are rare.
Game Corner[]
On January 30, 2012, There was a glitch where you could get shadow Pokémon without spending any Casino Coins. The Shadow Pokémon would not be able to be accepted, thus being useless. This is currently fixed.
Adoption Glitch[]
In the Adoption Center in the Legendary Shiny Adoption-only Pokémon list if you go to the address bar, change the last 4 and change it to a 5, The Pokémon will turn into X's and be 1 SnD coin. This also works with the other adoptions and the Avatar Store. However, this will just cause your SnD coins to be eaten up with no reward.
Alive Glitch[]
The Alive Glitch is the result of repeatedly clicking a Pokémon when it is about to faint. When it faints, it will be unmovable. However, it can still attack.
Ability Glitch[]
Ability Glitch
The ability glitch occurs with Blaze, Overgrow and Torrent. To perform the glitch, just leave the Pokémon with the ability out. Use a Potion or let Celebi (in Celadon Gym) heal it. The Pokémon will still have its glow. This is not a glitch as it says it activates at less than 1/3. It doesn't say it will deactivate at more than 1/3.
Invisible Enemies[]
When the speed button was added with the levels that bosses could attack, there was a glitch that makes the boss Pokémon invisible.
To perform the glitch, go to level Cinnabar Island, put all your party at the top waves until wave 30 where no more Pokémon are catchable. Place all of your Pokémon at the bottom and defeat all of the Kabutops, Omastar, and Aerodactyl. When they are all defeated, you can see the Invisible Bosses.
No Attack[]
This is actually common. Once, let's say Toxic was not introduced in v6.0 and was added in v6.1 as a TM, once that Pokémon you taught Toxic is used in v6.0, the enemies will freeze including your Pokémon but if your Pokémon already has a target, it will continue until the target's done.
In addition, if your Pokémon has no moves (from hacking), everything will freeze.
Final Gambit Glitch[]
When Victini/Mankey/Primeape used Final Gambit after it was released, they didn't faint. This glitch was fixed in V6.1.0.
Win with No Candy[]
Sometimes if all the candy was taken, the level would continue until you win. This glitch was fixed.
Transform Glitch[]
If a Mew is using Transform and learns a move while transformed, it will say the Pokémon it is transformed into even if it transformed back) learned the move (e.g. "Magikarp learned Mega Punch !")
Perish Song Survivor Exploit/Glitch[]
If you have Jynx or Lapras that knows Perish Song, if you pull them out right after they do Perish Song, they will survive and you can use them again.
Daily Glitch[]
On the Pokémon Center, in the Daily Gift, if you've finished even the latest level or complete the requirements, there is a chance that it will say "You are not eligible for this code" and when you go back, it will say "You already bought a Gift today. Come back tomorrow for another Gift."
Game Corner Glitch[]
On the Game Corner, if you have at least 300,000 Casino Coins, if you purchase a "Non-Evolved Shadow Pokemon," there are chances it will consume your 300,000 coins and it will say that you don't have enough coins.
Unable To Dispatch Glitch[]
Sometimes you'll be unable to place a Pokémon on the field. When you click it, nothing happens, or it blinks for a second and then goes back to being unselectable. It's usually the second Pokémon on your team.
Invulnerability Glitch/Health Multiplier Bug[]
In the two final stages before you reach the Unknown Dungeon, there would be times that the last two of the Elite Four and Ash would not be able to do damage to you at all. This also affects the first two of the Elite Four, however; you can still be frozen on the first, poisoned and confused on the second. Other enemy attacks do not do any damage at all.
Edit: This is said to be the Health Multiplier Bug. Every time the health resets between battles, your health is multiplied by a certain amount, which makes it look like you're not taking damage at all.
Black Screen Glitch[]
In the final three levels, when you finish the level, a black screen might appear and freeze the game. Luckily, Sam has added a link to fix this glitch in the Pokémon Center .
Wave Stop Glitch[]
In the Unknown Dungeon, the waves may stop appearing at a random time. This only occurs in blue version for some reason. This has been fixed.
Pokémon Trading Center Glitch[]
When searching for trades, you may have the problem when scrolling down. You may
Morphed and faded.
find that the Pokémon Center will fade and morph the trades together. If you go to another window or tab and back, the background will go black. This happens to FireFox more commonly than any other browsers.
Move Swap Glitch[]
Problems with the games programming caused Pokemon's movesets to swap when a player saved his game, resulting in Pokémon with moves that they shouldn't know.
This happened when I was training up a shiny Jynx, I saved, I shut my computer and came back and refreshed, and I had this...
Caterpie/Weedle Devolution Glitch[]
In V1.22, whenever a Caterpie or Weedle evolved in a level, after it ended they would devolve back into their starting form while keeping any moves they had learned. This glitch was patched by Sam quickly, so not many of these exist.
Time Stop Glitch[]
If you have a Pokémon without any moves and put it in field, it will "stop time" such that the opponents Pokémon stop moving. If you time it correctly, your Pokémon will keep attacking, but the opponent's Pokémon will be unable to attack. This doesn't work in PTD2, as once you transfer the Pokémon, they will relearn the moves.
Unlimited Normal Legendary Bird Pokemon[]
If using 6 shiny or shadow Pokémon the first time you try to beat the level to get your legendary shiny or shadow bird trio you can instead get unlimited regular birds. If one of the Pokémon knows Explosion or Selfdestruct and uses it, it will disappear from your available Pokémon. It will be in your box after the fight, along with another legendary bird. You can do this as many times as you like. However, once you obtain your shiny or shadow bird, the glitch stops working, so you may only use this glitch as long as you don't want the shiny/shadow birds.
Skip Power Plant, Seafoam Island, Victory Road, and The Elite Four[]
Go to the Pokémon Center and go to the Elite Four black screen fix, then click it and it will say that it has been fixed and the Champion level has been unlocked. (Note: you do not need The Elite Four level unlocked. That is the glitch. You skip the Legends areas and the Elite Four.
