Ruby??

[Alexander]

Obviously, Ruby has become confused with ‘Ruby WEAPON’.

Didn't you know? If you answer wrong 639 times and say it right in the 640th, Ruby Weapon will appear at Lv1 with none of his kickass attacks, and you can steal the White Materia from him before killing him. If you use White Materia on the Item menu, Aeris joins your team. Neat. I've done that once. And Aeris kick ass.
