Botolar

Botolar appeared in 1980 TV series called Denshi Sentai Denziman. Botolar is Vader Monster "46" of the Vader Clan. Botolar works alongside a squadron of Vader Clan fighters lead by Keller and Mirror initially to merely invade Denzi Land; however they become distracted and more interested in the emergence of a mysterious mermaid princess who lives nearby and appears to help and protect Akagi in particular. Realizing the power and potential that having her would hold to the Vader Clan, Botolar attacks the Denziman in hopes of trying to capture the mermaid; however the team ultimately protect her while convincing her to return to the ocean ultimately to be there for her people similar to how Princess Denzi was there for the Denzi survivors. The team ultimately defeat Botolar with the Denzi Lightning Fall, then with DaiDenzin after it grows giant.
