What is the 152nd Pokemon?

Sabooom.Sabooom.Sabooom. PIKABLU IS NOTHING BUT A MARILL!!!!!!!!!!!!!!
Obviously a kid saw it on the internet as a japanese beta pic of the G/S/C Pokedex and called him "Pikablu", because well, he looks sorta like a Pikachu. Hence, the birth of the all-too-famous Pikablu. Just wanted to clear that topic and end alot of confusion.

The 152nd Pokemon?

Even though it won't help you in Pokemon Red, that pokemon is Chickorita which is a Johto pokemon.

You can only get 151 Pokemon in Pokemon Red, not 152. Number 151 is Mew.

Why ever would you ask that question?!

Proboly Togepi, but you get it even with a game shark.

In Red, Blue, and Yellow, you stop at 151. If you're playing Gold, Silver, or Crystal, though, it's Chikorita. If not, you're wasting your time.

The 152cnd Pokemon is CHIKORITA, but that is a JOHTO Pokemon so you won't find it in Pokemon Red, you can only get it in Pokemon Gold and Silver.

You can only get 151 Pokemon in Pokemon Red. The 151st Pokemon is MEW.

Sorry buddy you gotta buy Pokemon gold/silver and catch Pokemon number 152

Pokemon 152 is actually a spare spot, for a pokemon but was unused due to the fact the didn't have a younger kangaskhan in game,its not able to fill and the pokedex only warents for 150 pokemon for completion, through a glitch it is possible to "have"

Actually you can obtain 152 different Pokemon, missingno which is #000 and is a glitched pokemon.

Actually the 152nd Pokemon isn't chicota , or missing , the bit about the un unused Pokemon in the pokedex bit is right cos when you use a completion code for g/s pokedex on gen 1 Pokemon games you end up it saying 152 owned and seen and they put an extra entry for farfeitch to cover up so the game doesn't glitch at the fact because the unused Pokemon in question isn't technically missing but has a connection to missing in a way as it is the missing number in the pokedex that also doubles as something similar in the pokedex I.E THE MAROWAK GHOST AT Pokemon Tower AND THE REASON IT WASNT INCLUDED IN POKEDEX LISTINGS OR GIVEN A BACKSPRITE IS BECAUSE IT IS UNCATCHABLE WITHOUT TRICKING THE GAME WITH CATCH Pokemon AND PICTURE MEMORY CHANGER CODES AND Glitches SIMULTANIUSLY BY SWITCHING THE GAMESHARK ON AND OFF AT THE RIGHT TIMES WITH THE RIGHT CODES AND PATCHING THE RIGHT HACKED VERSIONS I.E TEAM ROCKET EDITION OR BROWN OR SOMETHING OR MAYBE TWO AT ONCE COS I GOT THE GHOST IN T.R.E MYSELF MAROWAKS MOTHER ... THE PATCH PROGRAMMER INCLUDED THE GHOST IN BRUNOS LINEUP UNDER A DIFRENT REPROGRAMMED NAMES AS POLTERGHOST FOR THE EXCLUSIVE EVENT AND THE REASON BEING ... THE STEAL TRAINER CHEAT GIVING YOU A LEGIT MAROWAKS MOTHER WITH A MODDED Pokemon TYPE NAME ! IT COMES UP UNDER THE SAME NUMBER AS HAUNTER ON THE STATS SO IN T.R.E THEY HAVE IN TRUN TWEAKED AROUND WITH "THE CODES FOR THE MISSING NUMBER" AS it's REFFERED TO PROPPERY (CUBONES MUM I MEANT MY BAD) THE 1 FROM Lavender Town .. THAT IS 152 DISGUISED BEFORE YOU SEE A HAUNTER WITH ?? AS SEEN ON YOUR POKEDEX WHICH MAKES UP FRO THE MISSING DOUBLED 152 Pokemon .. THIS IS PROBLY TO DO WITH THE SO CALLED "CATCH POKEGOD" GATEWAY IN THE GAMES CODEING

Its scyther I know it bcuz I used a gameshark code to have/seen all Pokemon in the pokedex and 152 was scyther it's a secret pokemon

Pikablu is a marill so the 152nd Pokemon IS MissingNo!

Its your moms dildo. Bazinga.

152 is only available via hacking, and is just a big mess of pixels, like MissingNo.

It’s Ho-Ho, from the very first episode of Pokémon. Which makes 152 Pokémon total. Episodes name is “ I choose you”

My guess is that it's the game's way to tell us we have seen and captured 000 Pokémon. Since it was never meant to display 0 Pokémon (you should at least have your starter), it get the maximum, 151, and adds +1 trying to overlap and get to 000.
As to why it doesn't get to 000, I think that it is because there are more than 151 slots for Pokémon to be programmed in (that's the same reason as to why MissingNo. Exists).
