Ketsuban and MissingNo. are only closer to each other in Japanese Blue and international Red and Blue, respectively.
Red and Green only have 38 MissingNo. since the 39th of Japanese Blue and all other Generation I games is a GHOST instead.
The glitches that trigger MissingNo. also vary between versions and languages. The Old man glitch, for example, does not work in the Japanese games.
Also, Ketsuban can cause game freezes in Red and Green.
The Japanese games don't have corrupted Pokédex entries for MissingNo. so we know for sure that it is 1.0m tall and weighs 10.0 kg.
