Rob Liefeld does everything bigger and badder, from muscles to jaws to crazy-high projecting mask bits to sound effects. For instance, you can tell that this SPLOOSH onomontoPOWia is so loud it changed both Cable's and Wolverine's left feet into right feet!
That's some louditude, boys and girls.
Furthermore, I hope you'll note that in classic Liefeld fashion he has rejected the tired, patriarchal color norms, replacing the expected blue of the tons of water falling on these two (from a big water tower in a warehouse, because we all know how important it is to keep your crates well moistened) with a sickly green. The only thing better than fresh water that quenches your thirst is puke green algae water that slaps your feet on backwards!
Maybe someone was collecting Hulk sweat to make some kind of gamma powered mutant clone.
Blasted! Frankie how did you know of my evil plan?!?! YOU SHALL BE DESTROYED!
Feet are hard to draw! And Rob did neither the lettering or colouring.
