people wanted to see Pichu and Rotom's children, so here they are, well, 2 designs (for now), they where born with the Incubite and Succubite on their bodies, however these will stay inactive for 25 years, after those 25 years the stone will "awaken" making their libido explode and go berserk. they will recover eventually and continue with their lives like nothing happened, the only difference after having their stone active is an increased libido. they dont have names but the guy likes to study and investigate and the girl is always happy and full of energy for everything.
