Good Robotnik (Underground)

History
On an alternate Mobius where the Sonic Underground (Sonic, Sonia and Manic) are the evil rulers, Robotnik is the leader of the Resistance trying to take back the kingdom for the good of the people. At first, the "real" Sonic the Hedgehog obviously confused the good Robotnik for the real "bad" one, and made critical remarks of him. After a while, however, Sonic and the good Robotnik teamed up to defeat the Corrupt Hedgehog regime.

After capturing the corrupt hedgehogs, Good Robotnik showed the tyrants the misery their rule had caused the common people. After the Hedgehog rulers had a chance and vowed to right their wrongs, Good Robotnik stood by them to rebuild the Kingdom.

Appearance
Good Robotnik is essentially a doppelganger of his Mobius counterpart. Physically, the two of them are identical, except that Good Robotnik has a brown mohawk-like hair. He also wears the same attire as his counterpart, although his is slightly torn up.
