Shwonk/Shwonky/Swonk is Plasman's very best friend since they meet first in Smôlolo Academy. Shwonk is from a tribal clan of the North Galaxy of the Veruvian System. He is a hero who relies on the power of Nature and being one of Woodaken's best friend (both likes Nature).
Due to being very known, Shwonk got his own series named "Shwonk? Shwonk!", a spin-off.
