Cyrus is a character that appears in Sonic Underground. He is a friend of the Freedom Fighters and a highly driven tech expert due to his past.


Cyrus is a lion with tan fur and an orange mane, and wears a teal jumpsuit with green sleeves.


Cyrus is an old friend of Sonic's who he "coincidentally" meets. Cyrus was secretly working for Doctor Robotnik to prevent his father, Lionel, from being roboticized.[1]

The deal was that Cyrus would destroy the Freedom Fighters' Sanctuary and Robotnik would not roboticize Lionel. However, after finding out that the Sanctuary was for children, he instead destroyed Robotnik's communicator. Robotnik back-stabbed him and had his father roboticized anyway, so Cyrus then betrayed Robotnik and stayed loyal to the Resistance. He proceeded to help the hedgehogs in several of their missions.


Cyrus is quite intelligent and ingenious with mechanics, but is also gullible.
