What was Karna's other name?

Karna was also known as Radheya because he was raised by Adhiratha and his wife Radha. Though born to Kunti (making him Kaunteya - son of Kunti), he was abandoned and adopted by the charioteer Adhiratha. The name Radheya emphasizes his foster mother Radha. Suryeya would mean 'son of Surya,' which is also factually true, but Radheya was his primary alternative name in the epic. Indreya is not a documented name for Karna.
