All 7 emeralds are needed to transform.
well, there R 2 types of emeralds. The super emeralds, & the chaos emeralds. sonic (and others) uses either the super emeralds power or the master emeralds power.( the master emerald is the one that powers the super & chaos emeralds) P.S. my last answer was wrong if u R reading this again. P.S.S. I like cookies! X-3With the seven super emeralsds (the chaos emeralsds transform into super emeralds)
They are emeralds which has ultimate super powers. When sonic the hedgehog used the power of the 7 chaos emeralds it turned him into super sonic.
He turns into: SUPER TRUE DARK HYPER DARKSPINE CHAOS THESAURUS SHADIC THE HEDGEHOG
