Norio Wakamoto is a veteran Japanese voice actor with a long portfolio of characters that he's voiced. His craft is such that he often times gets pigeon-holed into a certain character archetype that fits a particular acting style of his.
This acting style is so prominent that you often have people try to imitate his voice, other voice actors/actresses that try to imitate him for fun, and even competitions at conventions (like at Moe Culture Festival 2012) for imitating him. These characters are usually evil (but not necessarily an antagonist), funny, maybe a little crazy. Characters like Onsokomaru (2x2 Shinobuden), Victoreem (Gash Bell), Garuda (Magical Quiz Academy), Katakuriko Matsudaira (Gintama), Amagumo (Desert Punk), etc.
Are there any characters (whether they fit this archetype or not) that were designed specifically for Wakamoto to play? I know there's Commander Wakamoto from Virgin Fleet, which I didn't find really matching the archetype, but it's hard to imagine that the names were just coincidence. Was Commander Wakamoto designed to be played by Norio Wakamoto?
