All of our worst fears are true. Dento has officially teamed up with MAGGYO, the only pokemon known to match him in pure insidiousness. A pokemon so diabolically evil that even Pansage, in all his deer-raping, chinchilla-slaughtering infamy must have shivers running down his spine right now. This, ladies and gentlemen, may be a good time to panic and freak out.
Now he can use electrical torture, along with everything he can do now.
Just as the tuneless echoing prophets of Ieru Ka Na predicted, everything will indeed end with Maggyo.
You might be on to something: Ishizumai came before Maggyo, in both the song and in terms of Cilan's captures. They might be putting in secret messages, warning us of what he'll use against us next.
