Krudzu (later known as the Krudzu Hybrid Hydra) was a mechanical weed. It was a rapidly growing vine with numerous fly-trap-like mouths.
A special team consisting of a SWATbot and a Burrobot created Krudzu, designing it to grow from seeds. It was tested on the South side of Robotropolis, and caused the site to collapse. Showing Dr. Ivo Robotnik the test result, the SWATbot was almost destroyed for breaking Robotnik's "No plants" rule. Then Robotnik saw that it was a Mechanical plant, that promptly tried to consume Crabmeat. The SWATbot explained that he had a Burrobot customized to spread krudzu seeds wherever he can roam. Burrobot planted seeds all over the Great Forest, with the intention of having Krudzu devour the Great Forest, and smother the Knothole Freedom Fighters. Almost immediately, Antoine D'Coolette discovered it, was wrapped in Krudzu vines, and had to be rescued by Sonic the Hedgehog. After Sonic, Rotor, and Princess Sally took Antoine to Knothole and removed the vines from Antoine, Tails mistook the Krudzu for dried cuttings, and watered them. Fearing the worst, everyone was surprised when the Krudzu burst into an electrical fire. Rotor examined the Krudzu and discovered that it was weak against water. Sally and Tails then pointed out the day's weather forecast which called for rain. Sure enough, the Krudzu all short-circuited during the storm. (StH: #1)
Searching through his father's belongings one day, Antoine found half of a map in the hilt of General Armand D'Coolette's sword. On one side of his half piece was a complete drawing of the Budding Circle, where Dr. Robotnik originally unleashed the Krudzu. At the same time, Snively, searching through his uncle's files, found the opposite half of the map—also with one complete drawing of the Budding Circle on one side. Each set out toward their destination on the South side of Robotropolis, where the Budding Circle once existed. (StH: #110)
At the alleged site of the former Budding Circle, Snively sent a squadron of Eggbots to dig in search of any remaining Krudzu seedlings that he could use as a weapon against his uncle to take over Robotropolis. In the meantime, Antoine arrived on the scene and tripped over a pile of metal bars, causing a commotion. Snively sent the Eggbots to investigate and silence the intruder so as to keep his plot against Robotnik secret. Ultimately, the Freedom Fighters came and destroyed Snively's Eggbots, foiling his plan. At the end of the day, no remaining Krudzu seeds were discovered.
A Badnik Hybrid
After the nuclear assault by Station Square on Robotropolis, a single Krudzu root managed to survive the blast. It had previously been part of a project by Robotnik to improve upon his former creation. After having burrowed to safety, it re-grew and merged itself with parts from other scavenged Badniks, becoming the Krudzu Hybrid Hydra.
During Sonic's search for Dr. Eggman in the Eggdome, the Krudzu Hybrid Hydra followed Sonic and ambushed him. Though Sonic was able to defeat it once, it quickly revived itself to full strength and continued to engage Sonic. As it was about to finish Sonic off, Dr. Eggman, wanting to defeat Sonic himself, sent a robotic hummingbird to detonate the Krudzu Hybrid Hydra. A confused Sonic left behind the charred remains at the Eggdome. A sprig of the Hydra survived, and was later found by Cubot aboard the Death Egg Mark 2. Realizing its destructive potential, Eggman allowed it to merge with a model of Titan Metal Sonic and sent it to attack Team Fighters. However, the group of heroes tag-teamed the construct and knocked it into the ocean.
Krudzu Hybrid Hydra survived the Titan Metal Sonic's destruction and went on to possess the body of Metal Knuckles, who had been knocked out during the battle in Albion. After attacking Team Fighters and Knuckles the Echidna, it was eventually defeated by Sonic. It then proceeded to seemingly absorb various machinery laying around in order to take on a new form; however, it was quickly defeated by Shard the Metal Sonic, who was initially watching the fight in secret.
- The Krudzu is deliberately based on kudzu. Kudzu was introduced to America from Japan as both a decoration and a means of preventing soil erosion. Inevitably, the kudzu growing went out of hand. Now, it is a weed that takes root deep in the ground, and grows like wildfire. It has been known to entangle cars, fences, and even small animals.
