While one of the best villains of the series, Elder Toguro was a bad guy where everybody was rooting for his demise.
Along with his much stronger brother, he basically is one of the most powerful demons in a very mafia like environment.
I think most people were surprised that he could fight just well enough without his brother.
He was confident enough to fight three demons at the same time.
And totally massacred them.
Kuwabara was absolutely terrified to fight him in the finals.
With good reason, as he almost died countless times against him.
He pretends to lose against Kuwabara to make the odds for his team work better in the betting odds.
I was surprised but delighted to see Younger Toguro kick him about 5 miles into the sky.
They managed to survive, yet in very bad shape. Shinobu Sensui senses his dark energy and comes to recruit him.
He agrees to be eaten by Gourmet, knowing his chances of being taking over were high. Having a crazy amount of powers, I was surprised Kurama agreed to fight him alone.
And Kurama trapped into a tree that will give him an eternity of suffering. Exactly what he deserved.
