So you know how Tiamat is nicknamed "Ti Ma" in Chinese, where the "Ti" is the first character of her name and "Ma" is just "妈". So the MTL translation does this weird thing where if those two words are combined, they think you're saying "Timmeh!" like that South Park character, so they often translate Tiamat to be nicknamed "Timmy".
But sometimes I wish these toys were real...
