>>52829759No, Type:Null was a failure and they had to put a power restraining mask on its head and freeze them because they did nothing but go berserk and try to kill everyone. The rival in SM took pity on one and thawed it, using it as his signature Pokemon. Pic related is Silvally, its evolution (?) that the rival discovered (Type:Null was a codename, but he gave it the name Silvally when it "evolved"... or in the anime, before it evolved). It turns out that building a strong bond of trust with it allows it to control its power and it no longer needs the helmet. THEN the type changing gimmick starts working.
It was a cool Pokemon, even if SM didn't really do much with it.
