Taking a second look and it only just dawned on me that this isn't R.O.B the fighter but one of the few R.O.B. Squad enemies you fight in Subspace. (As if the description didn't give that away already lol) And it's not even the launcher variant that's distinctively green and fires a missile which everyone remembers the most.
Point is, seeing an obscurer enemy who you only encountered in maybe 5% of the whole game and doesn't stick out much visually from the R.O.B you eventually play as getting some tribute fan art of them suddenly makes this piece a bit more special.
