Tango gratefully welcomed Proto Man when he came to Light Labs. Later, Tango came to the aid of Mega Man to help him fight Sonic the Hedgehog, alongside Rush and Eddie. However, after Mega Man had made peace with Sonic after discovering they had been tricked, Tango ceased to oppose the hedgehog. Tango then returned to Light Labs with the heroes to find Dr. Light getting kidnapped by Bass and Metal Sonic. Despite his efforts, he was unable to save the doctor.
- Similar to some of the characters in the series, Tango was named after something music related; the tango dance.
