Xanthi was my favourite character in the "Who is Donna Troy?" mini-series in the "New Titans" comics from DC (#51; US winter of 1988). Wonder Girl (soon to be known as Troia), plus Xanthi and ten other aliens were brought to New Chronus in order to be trained along as replacements for the waning Titans of Myth.
Some friends of mine were deeply entrenched making teddy bears at the time. I happened to mention how much one, unfinished, ear-less, bear resembled Xanthi - and... they made the above stuffed Xanthi as a surprise gift.
