>>44660966the last one is not surprising.
however, it is not quite correct. you can paralyze an electric type with thunder wave for example.
what is actually true is that a pokemon of a certain type cannot be affected by the secondary status effect of a move matching its type. you can't burn fire types or freeze ice types. poison types cannot be poisoned. this is very well known.
what was surprising about this, is that it extends to more than these types. this is what was just relatively recently found out.
for example, electric types can never be paralyzed by moves like thunder or thunderbolt.
ghost types cannot be paralyzed by lick. psychic types cannot be confused by confusion.
the most surprising: normal types cannot be paralyzed by body slam.
