Takanuva gets repeated ones against the Makuta in Karda Nui. On more than one occasion, the darkness he got infected with influences him to get seriously pissed off against them, and he may well have killed them all singlehandedly had the other Toa not been present to calm him down.
"But I'm not my "kind", not anymore — your shadow leeches saw to that. I'm half Toa of Light, half Toa of Shadow. This was what you wanted, wasn't it? Toa consumed by darkness, Toa not hampered by things like mercy or morality. Well, now you can choke on it."
