  • This series combines elements from both the 1985 and 2011 series, although closer in plot and lore to the 2011 one, even if with some differences:
    • Much like the 1985 series, Pumyra never became alligned with Mumm-Ra and remains one of the most trusted allies to the ThunderCats.
  • It released after the installment of Roar primarily for both a serious and a slightly comedic ThunderCats incarnation to air at the same time.
  • YouTuber Caleb Hyles performs the theme song.
