Many other custom contraptions, like the TNT rockets for example, had abilities before the alien parts came. TNT rockets exploded few seconds after impact and the electric engine made contraptions faster. Mostly because the electric engine was one of the more powerful contraption pieces, Rovio decided to move it to alien parts.
