Hiiragi (Hiragi?  However it's 'sposed to be 
spelled!) from Mon Colle Knights!

He's a mad scientist and a riot as well.  The 
computer he made to sense Mon World monsters looks 
like a chicken and clucks like mad when it finds 
one, he has a giant vacuum to retrieve Mondo and 
Rachna (the actual Mon Colle Knights) whenever 
they get a monster alert and he seems to be 
completely obsessed with various bodily functions.

Add in the inept but earnestly evil Prince 
Eccentro and well!  I *wish* I could find 
subtitled MCK!
