I liked these two all during playtest and I think they'll be fun in widely-recruiting games of Marvel: Legendary. When I saw the final art I was even happier, probably my favorite pieces, oozing personality.
The Bug Monster is a one-card game dynamic! When it shows up at the start of the game, you're saying, "Thank you, thank you for springing out of nowhere and eating one of my lousy Chang Sing Warriors" (or maybe a Mediocre Hero like the Jerk . . . ). But if it does you the favor of eating a hero you can afford to lose, that's not the end, it gets shuffled back into hiding. The more of your 0-cost Heroes you get rid of, the closer you are to losing a Hero who matters. Eventually the Bug Monster gets a happy meal.
