The Bugger (把妖虫 バッカー Wa Yōchū Bakkā?, lit. "Demon Insect Guard Bugger") is a recurring enemy in the Contra series. They are newborn aliens which quickly scurry along the floor or ceiling. When facing intruders, they will either drop diagonally from the ceiling for pouncing or leap at them.
In Contra, they only appear in the final stage, Alien's Lair. They are the only critters running on the ground of this level, and even for their short appearance, they make their entrance just a few steps before the final boss. This makes this area arguably easy as the player only has to watch out for top and bottom Wadders and Gels for the majority of time. During the final duel against Gomeramos King, while some Buggers will just rush past and ignore the player, others will intentionally make an attempt to kill them.
Buggers make their return in both versions of Super Contra, although they appear in different stages. In the arcade version, they are seen harassing the player in the third stage, Jungle, by dropping from the top of palm trees or by leaping from the ground, aided by trees present in the foreground that block the player's view; whereas in the NES version, Buggers are spawned from Eggrons in Stage 7 as the player makes their way to the deep bottom before reaching Dethgerbis. This variant is much faster than that from the arcade version.
In Operation C, they are encountered contained inside of large glass tubes in a laboratory, from which they break out and scurry at the player.
In Contra III: The Alien Wars, they appear for the third time, engaging the player the same manner they did in previous games. Here they will be defending Gomeramos King, just as they did in the first game.
- The shape and way these enemies behave, as well as the type of organic hatches they are born from, are a direct reference to the facehuggers and ovomorphs from the Alien franchise.
- Furthermore, the word "Bugger" is a homonym of "Facehugger".
- The Maksurion, an enemy from Gradius II, also by Konami and based on the facehugger as well, behaves identical to a Bugger.
