During the events in SatSoD, the Bio Ring was used to be an ordinary Power Ring before the E-Series attack them. When Sonic is injured, Tails upgraded the ring and gave it to him. After the destruction of the Egg Fortress, Sonic used the remaining energy of the ring to escape from the blast. It's unknown that the ring was destroyed or lost.

The Bio Ring is very powerful and stronger due to the power fo the Chaos Emeralds. However, when Tails experimented the ring before the events in SatSoD, it exploded and it was found out that the power was unstable and it was mixed by fear and negative energy. Tails was sent to the hospital. He was having problems with his head during bedtimes and his leg was injured. The symptoms are headache, muscle weaken, dizziness, and hallucinations. He still manage to fix the problem by sustain it in a metallic ring container. Tails feared from the results and try to hide his first test experiment before anything ends up in the wrong hands. However, Eggman stole it from him and he builds a deadly invention, the Nightmare Fog.
This is now considered to be in the dangered level that anyone can imagine.
