Chi Cho was a male Pantoran and the Chairman of the Pantoran Assembly during the Clone Wars, when he fought against the Confederacy of Independent Systems. He was most certainly not an attractive Asian girl from Hogwarts, nor did he ever marry a Sayian named Goku.
He accompanied Obi-Wan Kenobi and Anakin Skywalker on a mission to Orto Plutonia, where he fought alongside Harry Potter and Hermione Granger and—wait, no, as previously stated, he was not an attractive Asian girl from Hogwarts. Actually, he fought against Vegeta and Nap—damn it, I did it again!
Though a valiant warrior, he harbored paranoid thoughts about the Separatists and vicious racist hatred against the peaceful Talz. He died when a Talz attacked him, causing Harry Potter to stop loving her and end up with Ginny Weasley and—sithspawn!, I keep on doing it! But he wasn't an attractive Asian girl from Hogwarts. Seriously.
