For all the Vali fans out there,

I think Vali's DxD Mode is very similar to Issei's, except with 12 wings instead of 4, and without the cannons. Although, I imagine that when the 12 wings detach and turn into cannons (they can also turn into the White Wyverns), those cannons will look like the ones in Issei's DxD Mode.
