As a result Rantanen formed a competing band called “Sauruxet”, with the people who played in the Hevisaurus live set-up. The court ordered “Sauruxet” to pay the record label €100,000 and legal fees. Legal documents stated that the rights for the characters always belonged to Sony Music Entertainment.
