Shellshocker is immensely powerful, and anything with even a chance to scratch his body armor is gunned down with blasts of water. You're wandering through a forest route when something falls from the sky before you. After a bright flash of light which forces you to shield your eyes, you look up to see a strange creature taking shape in the impact crater. Initially appearing as a strange jumble of helixes and multi-colored flesh, it coalesces into a humanoid shape once it "sees" you. It begins to advance, slowly hovering towards you. Panicking, you call out Shellshocker, and you see the large turtle take its place in front of you. The creature pauses briefly before flashing its "eyes". Shellshocker drops like a rock, unconcious. You barely have time to cry out in shock before everything goes dark for you as well.
