there is also the case of hidden AP carry bottom support but there not that much of a "support" imo, they poke allot and do allot of damage and can get just as much kills as there adc some times.

possible examples include nidalee,lux,karma,morgana  and any mage with decent CC can do theis role too but the 4 I have said are the most common you'll see.
