Mega Delta Venusaur

I chose Delta bulbasaur as my starter, and got a male with modest nature. I want to keep it, but in looking in the “battlers” files, it seems that male mega delta venusaur has no back sprite. Will that cause problems in the future if I try to mega evolve?

It will mega evolve, it won’t cause any problems, just that there’ll be no indication on screen that it mega evolved.

Alternatively, you can download(Name is 729b_1.png) and add this in the battlers

Thank you!!
