S. Sreesanth
The cricketer turned politician, S. Sreesanth was one of the wicked and aggressive guys on the field during his playing days. He showed his colours from domestic cricket itself as the pacer dared to mock Sachin Tendulkar and Virender Sehwag during a domestic match in starting point of his career. Both of them got so angry over him and asked him not to come anyway closer. This was only one of the incidents as many there were many such incidents in the list like slap gate, dance after six off Andrew Nel etc. Surely his acts make him the wicked Indian cricketer ever.
