Why is Jirachi and Dome Desire steel type?

Question

it just doesn't make any sense

Answer 1

Well, Jirachi's arrival coincides with the arrival of a comet. While having a mystical (psychic) quality in most mythologies, in real life comets are composed of ice and metallic elements (steel). As for doom desire, game freak already has a gen 3 event Pokemon with a base 140 power psychic move (deoxys, psycho boost) so they probably didn't want another. Also, steel is Jirachi's primary type.

Hope this helped

Doom Desire actually causes a bunch of comets to be launched. So Doom Desire is Steel for the same reason Jirachi is Steel.

Answer 2

I reason to believe that Game Freak wanted to have that move to be a steel type. Also if it was any other type, Jirachi won't get the STAB from the move. If it was a psychic type move, then it would be a stronger clone of future sight. Like all moves, Doom Desire is at at the hands of Game Freak and are open to their minds.
