While never officially confirmed by those involved with the show, the character designs for the band members Skwisgaar Skwigelf and Toki Wartooth also seem to be based on popular heavy metal icons.
Skwisgaar Skwigelf, the lead guitarist, appears to be inspired by Alexi "Wildchild" Laiho, the lead guitarist and vocalist of Children of Bodom. Still others believe he is based upon Jesper Stromblad of the Swedish melodic death metal band In Flames.
Toki Wartooth, the rhythm guitarist, could be based upon Opeth's Mikael Akerfeldt, Hypocrisy's Peter Tagtgren, or Meshuggah's Fredrik Thordenda. However, his appearance and name similarity lead many to insist he is based on Timo Tolkki of the Finnish power metal band Stratovarius.
