List of Pokémon by index number (Generation I): Difference between revisions

In each [[Pokémon games|Pokémon game]] of [[Generation I]], all {{OBP|Pokémon|species}} have an unseen [[index number]] used to identify them in the game's {{wp|Read-only memory|ROM}}. Unlike later [[generation]]s, the Pokémon are far from being in order by their [[National Pokédex]] [[List of Pokémon by National Pokédex number|numbers]], and most [[evolution]] [[List of Pokémon by evolution family|families]] are extremely fragmented. In addition, the [[glitch Pokémon]] [[Missingno.]] permeates the list; all other glitch Pokémon are either indexed 0x00 (dec 000) or after {{p|Victreebel}}. Since {{p|Rhydon}} is index number 0x01 (dec 001), many glitch Pokémon will become it upon capture, due to the [[Rhydon glitch]].

When connected to a [[Generation II]] game, many of the glitch Pokémon will appear to the other side to be a {{cat|Generation II Pokémon}} and are occasionally tradable. In the list below, the name of the Generation II Pokémon in parentheses after the glitch Pokémon's name is the equivalent Pokémon in the Generation II games. The conversion of Generation I glitch Pokémon index numbers to Generation II index numbers simply is Johto Pokémon in National Pokédex order, starting from 0xBF (dec 191)—the index after the last valid Pokémon in Generation I—and ranging to 0xFA (dec 250), then continuing by filling the indices that correspond to Missingno.; only Ho-Oh and Celebi are misplaced.

Please note that the Ghost, Kabutops Fossil and Aerodactyl Fossil Missingno. are not of type Bird/Normal and use the same type as the last Pokémon in memory.

<!--Please do not change this into a National Pokédex order. Index number and National Pokédex number are NOT one in the same.-->

* In an interview with [[Shigeki Morimoto]], he confirmed that there were originally going to be 190 Pokémon in Generation I.<ref>[http://www.smogon.com/forums/showthread.php?t=78267 Smogon Community - There Were 190 Pokémon!]</ref> This would mean that the 39 [[Missingno.]] are formatted Pokémon.
