Sixty Five Million BCE , amongst heavy volcanic activity, an asteroid crashed into the Yucatan Peninsula, wiping out the worlds dinosaur population.
Except two Dakotaraptors. The impact of the asteroid also triggered a magical well that trapped the beasts in a state of suspended animation. Over the years, the magic changed their DNA, allowing them to change their forms at will.
Upon awakening, they found themselves in a world dominated by mammals, especially humans. Seeing this as a disgrace, the male Dakotaraptor, going by the identity Victor Veloci, vowed to rid the world of humans by any means, even changing the global climate. The female, believing that brute force gave way to harmony, left Veloci, going under the identity Joanne Moynihan.
After over two decades of foiling Veloci's plans, the Dino Squad has grown up and split up for their own college. Since then, there hasn't been as much as a blip on Veloci's radar.
Until now...
Part of the multi-crossover story arc, "Other Visits," occurring in the New Timeline after "Friendship Games". In this case, Dino Squad.
