Galaxy Eyes Photon Dragon

Galaxy Eyes Photon Dragon is the ace monster of Yuuko Pegasus and strangely enough, even though she is the XYZ user of the siblings, this card is not an XYZ, rather, a gateway to the power of XYZ, she uses it due to it's immense raw power. For some reason it befits her ideal that she must surpass the strong to become more powerful and believes in an eye for an eye, however, she wants to gain more power, this card seems perfect, however merciless may the means to the end be, yet, still upholding a line.
