So I made Alastor one of the recurring villains to go against The Clown Squad (that's the trio of Blake, Rudy and Zacha) and the reason he is around is because he have a both a love crush on Katya and a scheme to get the power of blue flames (flames that can burn demons and angels alike).

Al simply sneak attack Blake, Rudy and Zacha knock them out, just get close to Katya, Lechugin who is the last line of defense try to attack him but he was trap and get choke by one pf Al's shadow tentacles (poor Lettuce always getting torture by evil people), Al simply choke Lechugin to make Katya angry.

But Rudy manage to recover fast and he is going to attack Alastor in the future, both of them have history and Rudy have beef with the Radio Demon, Al's interest in Rudy is simply a "I see myself in you" idea where Alastor sees many similarities between himself and Rudy and well he sees him as his eternal rival and father figure, Rudy just hates his guts.

Katya, Lechugin and Rudy belongs to me
