This is the first time that E-tanks were in any megaman game, so it's understandable Rock wouldn't know about them.
This... is version 2! As you can see, the panels that contain the logo, date, comic title, ect are actually symmetrical this time, I've ditched the diamond plate aesthetic of v1 for a more "abstract" checkerboard motif, and I got a new logo! I feel like it's a big upgrade over version 1.
