- This Tyrant may be a reference to Territorial Rotbart from Xenoblade Chronicles. In addition to them both being "Territorial," they are both level 81, red-furred, giant ape-like monsters that can be encountered early on from the beginning of their respective games, in grassy areas surrounded by low-level monsters.
