First appearance of this enemy in the series; it is encountered at the end of the Occupied City Street.
The heroes arrive to what appears to be a dead end, with a high wall blocking further progress. After a brief moment of uncomfortable silence, the earth suddenly begins to tremble and the sound of approaching stomps can be heard every time louder and louder. The wall suddenly breaks apart and from the opening emerges a humongous monstrosity: Slave Beast Taka.
Taka is an alien monstrosity that somewhat resembles a gigantic tortoise. It has an equally enormous hive affixed to its back, from which it releases swarms of flying insect-like aliens. The hive's opening can be destroyed, preventing any more aliens to come out. Taka also has arms that strangely resemble human brains.
Taka can also vomit myriads of disgusting maggot-like creatures that will start crawling on the ground. Another ability consists in extending its neck a great distance in order to bite its prey with its powerful jaws. If this wasn't enough, it can also unleash a powerful energy blast from its mouth.
This boss can only be harmed by damaging the big, core-like heart exposed underneath, although this too can shoot back projectiles at great speed.
In Legacy of War, Taka is now fought from a top-view perspective. It has variations of its previous attacks:
- Breathes a large stream of flame.
- Releases bug-like aliens.
- Elongates its neck to bite the player at a distance.
Slave Beast Taka initially behaves and attacks the same way it did in Contra III, although this time its heart is absent and is instead replaced by another hive. The new weak point is its head.
After sustaining enough damage, it will turn around and reveal a giant humanoid face, commencing the second phase of the boss fight. Its two attacks are either vomiting (sometimes having dead bodies to come out) or sniffling, where bugs fly out.
The battle with Taka takes place in what looks to be a large spacecraft. The monster makes its entrance by smashing down an automatic door and breathing flames at the player. Its eyes burn with fire. In this game, the alien beast can be damaged by firing at any part of its body.
Taka's attacks are the same as in Contra III, although with some new tweaks:
- Taka vomits alien insects at the player. These remain pacing back and forth on the ground, not going anywhere so the player will have to take out these crawlers.
- Taka breathes a flame stream toward the player's current position. The flame lasts quite a bit and inflicts additional damage, so it is advised to move away as quickly as possible.
- Taka takes a few steps forward and stretches its neck to bite the player. During this attack, Taka's full body can be briefly seen.
- Taka releases swarms of flying alien insects out of its back. Unlike Contra III, it does not have a hive to be shot down to prevent more bugs from coming out, so the player will have to keep on negotiating with any flying insects released by Taka. These bugs spew acid at the player and take a few shots to be taken down. If not taken out quickly, they can cause a lot of problems as Taka will continue attacking regardless they are present or not.
- Taka takes a step backward before shooting a long and deadly laser beam from its heart/core.
- The English instruction booklet for Contra III: The Alien Wars names this enemy as "Beast Kimkoh". However, in the Contra universe, Kimkoh is a totally different creature, most known for being the final boss in Super C for the NES. Whether this name change was an error or a liberty taken by the localization team is unknown.
- The European instruction booklet for Super Probotector: Alien Rebels names this enemy as "Vicious Slave Hawks" (the kana タカ Taka can be transcribed into 鷹 "Hawk" in kanji). However, in the English instruction booklet, the same name is given to another enemy otherwise known as the Metal Alien.
