>>56660497According to interviews, there was supposed to be a helmet pokemon (is that thing with the tongue out legit?) that was unrelated to both Karrablast and the snail with a shield which where supposed to be rivals, so escavalier was probably related to the helmet as a mono steel pokemon.
When they got the idea of Karrablast stealing the shell of a snail they just turned the helmet into a snail, deleted the snail pokemon and turned the armor into a bug thing.
