There's been far more obscure characters to get Appreciation threads, so I figured, why not give Ruby her due?

Created in 2008 by longtime X-Scribe Peter A. David and artist Valentine De Landro, Ruby hails from Earth-1191. You can probably guess who her parents are. First appearing in X-Factor Special: Layla Miller, Ruby went on to co-star in X-Factor (Vol. 3) #41-50, as a founding member and leader of the Summers Rebellion. The Summers Rebellion fought a desperate struggle for survival against those who would exterminate Mutantkind.

In 2015, PAD would create an alternate version of Ruby in Future Imperfect. Set on Battleworld during the Secret Wars event, Ruby hailed from the realm of Dystopia (Earth-69413). In this world, Ruby rebelled not against mutant extermination, but the tyranny of the mad Hulk known as Maestro.
