Bioe's design has stayed pretty consistent over the years. Probably because its so minimalistic and his overall figure is pretty bland but still interesting enough to keep you interested.

But I haven't drawn Bioe's back too much or the colors that his ring swap to. The ring on his backis called the "Omega Ring" which he got after his adoptive mother "Dr. Victoria Marco" was killed.

The omega ring can boost his base stats whenever he needs so he can gain an upper-hand, but since he doesn't have a brain he can't exactly use it to it's full potential. The colors that his stripes swap to will tell you what mode the ring is set to:

• RED: Omega = Power (Decreases defense)
• BLUE: Alpha = Speed (Decreases power)
• GREEN: Zeta = Defense (Decreases speed)

Then YELLOW / GOLD is just nothing, but even without the ring Bioe is still more powerfull than most of the gods in Greed
