In Digimon Story Super Xros Wars Red / Blue, Shoutmon X3GM is considered a Type: Dragon, Race: God Dragon. Probably his race is "God Dragon" due to his Death Blow "Breath of Perun". Perun is a god of Slavic mythology, associated with wars and thunder.
Interesting that this Skill in the game is of the Thunder attribute, being the only one that he learns from this attribute.
