The Kaktos are an incredibly rare species. They’re numbers have dwindled to around 20,000 due to poachers who hunt them for their nectar, which can be sold for a fortune on the black market. They’ve grown to be very suspicious of outsiders.
Kaktos live in packs of up to ten members. Their pack leaders are usually the largest, have the most limbs, and the sharpest needles. They spend their days filling up on water, hunting down small animals to eat, and fighting with rival packs.
Kaktos females will pick their mates based on who can produce the most beautiful flowers on their bodies, as it is a sign of good health.
- Green Needle was based on the Alien Force Omnitrix toy's auditory illusion when the Brainstorm hologram was inserted, with some people hearing the name "Green Needle".
- Ben, when transforming into Green Needle for the first time, got the name after remembering hearing the illusion first at a fan convention.
- This is the second alien Der_Eisen has collaborated on an alien with DFreak22. The first was Scraptile.
