I was inspired by the megaman games when had this in mine with intention what if a scientist from megaman universe created their own version of Bass & Treble. But as you see they have more of megaman z and zx design mainly as they updated themselves when they come out of stasis in that time period. Despite how old of designs they are both yoichi and kurisu are very sophisticated and able to adapt to the time period with both having a unique bassnium energy core that powers them that also been fused with evil energy that bass himself wielded without any ill effect to either of them
