Highschool DXD x Transformers Prime (with a Oc/male reader with another oc.)

After an unexplainable dimension collision, sometime after Megatron finally knows what oppression really is and joins the good side, along with soundwave and shockwave, Optimus prime, along with ratchet, bumblebee, and the other three, with two others, get sent into another dimension where there are angels, fallen angels, and devils, and they also... turn human!? I don't own TFP or H.S.DXD, also support the creators.
