MissingNo.? Should I?

[Vipershark]

no
all of the missingno versions are triggered by your name

that's why some people get regular missingno while some get the ghost and others get the kabutops skeleton or aerodactyl skeleton

basically what happens is that since their sprites aren't part of the 151 but are still in the battle sprite "area" of game data, the game loads them when it goes outside of the 151 range to load missingno
