Some scrapped Pokemon that intrest me are:
Honoguma- a Pikachu fire bear
Unnamed turtle- GS beta Pokemon that bears a resemblence to Tirtouga over 10 years later
Latiaziken, a Pokemon beta that was the combination of Latias and Blaziken
And, last of all, the original color of Excadrill, which looked cooler than the current coloring.
What's your opinion?
