Wow I didn't know that was possible! I just knew that Mindwipe had a slot for Skystalker to sit on top of Mindwipe in jet mode, like G2 Dreadwing & Smokescreen, and that looked cool to me, but now I'm really glad I got Skystalker. I actually bought Mindwipe for nostalgia it reminded me of G2 Sky Jack, which I had as a kid and loved.
