Sci fi comedy manga Sgt. Frog is celebrating both the birthday of its titular character and the 25th anniversary of its serialization, and to help the series commemorate the occasion, One Piece author Eiichiro Oda has sent along an original illustration featuring the protagonists of both works posing together (below).
Kadokawa Shoten began serializing Sgt. Frog by Mine Yoshizaki in their Monthly Shonen Ace manga magazine in April 1999. Viz Media also publishes an English language version of the series. Crunchyroll currently streams the Sgt. Frog anime adaptation, and describes the series:
Keroro is Sergeant Frog – the leader of a platoon of warriors sent to conquer planet Earth. But when the amphibious invaders discovered how much humans enjoy dissecting their comrades, the troops were scattered, the mission was aborted, and Keroro was abandoned. Now, this once proud soldier spends more time wielding a vacuum than he does the weapons of war. It’s a far cry from the glory of battle, but hey, at least he’s got his own room. And though the invasion may have slowed to a hop, Sergeant Frog still occasionally yearns to overcome his karaoke addiction and reassemble his troops.
