Best and worst fill-in VA in the FW series?

[Prowler]

I think most of us can agree that whenever another VA had to fill-in for the absence of one of the regular VAs, the result was not too good.

It's hard to say which one was objectively the worst since pretty much all of them sucked. But I'd say the worst was the one who filled-in for Pat Fraley. Krang's voice was just unnerving in that episode or two Pat Fraley missed.

Dishonourable mention to the guy who voiced Raphael in that season 3 episode where the Turtles buy Splinter a sword as a gift.

The best fill-in VA? The only one who was decent was the guy who voiced Shredder after James Avery left. He had big shoes to fill, and yet I think he did a solid job.
