Iron Crown ex - Twin Shotels

[Just_Dwindle]

I have a question, If my active Iron Crown ex uses the attack Twin Shotels while my opponent has Manaphy on the bench, would the attack effect the bench?
and again if Jirachi is on the bench would the attack effect the bench?

Twin Shotels says it's damage is not affect by "any other effect".
Any time an attack says it's is not affected by any effects, it means it.
The damage goes through
