I found something else but, this is about Generu Serutasu and Aruserutasu. It is true, her pheromones do enchance Aruserutasu abilitys in afew ways like his claws and his mucus balls. The pheromones also seem to make Aruserutasu alot more aggressive and Aruserutasu is considered to be a soldier defending its queen, Generu Serutasu, to the very end, even if he needs to sacrifice his life to save her. Also it seems the Aruserutasu lets the Generu Serutasu kill and eat him by pure instinct without fighting back because, it could be how the two mate with each other.

This comes from the actual game.
