Pandavas, particularly Arjuna, were hostile. The Mahabharata mentions Karna as the main challenger of Arjuna at sporting and skills competitions. At martial sporting events, Arjuna and Karna were often equal, though in his self-bragging style Karna once announced, states McGrath, that "he will perform any feat that Arjuna has accomplished and do it better". At the svayamvara competition of Draupadi, where she is expected to choose her husband, both Arjuna and Karna are present. Arjuna and his brothers, however, are disguised as mendicant Brahmins. They use this false identity in exile because Duryodhana had attempted to kill them using various schemes, including burning the lacquer house – custom built for the Pandavas by Duryodhana – along with the forest while they were sleeping. There are some variations regarding Karna's participation. Some renditions show Draupadi refusing to marry Karna on account of being a Sūta, while some other versions describe him failing to string the bow by the "breadth of a hair". In the end, Arjuna succeeds in the task, However Karna objects that the competition is only meant for Kshatriyas, and Brahmins such as "the mendicant who just strung the bow" should not be competing for the hand of Draupadi, a Kshatriya bride. Duryodhana supports him. The gathered Kshatriyas too angrily support Karna, for they against the mixing of varna (here, Brahmin-Kshatriya marriage). Arjuna maintains his calm, continues to hide his true identity, insists that he is a "Brahmin who fight". Arjuna's accomplishments and calmness win Draupadi's heart. Draupadi picks Arjuna and awards the garland to him, signify that she chooses to marry the disguised-Brahmin Arjuna. The varna-based discrimination and verbal insults on Arjuna, for lovely Draupadi's hand, one that Karna initiates at the time of Draupadi's svayamvara competition comes back to haunt him many times through angry Bhima and others who remind Karna that he is merely a suta-putra (son of a charioteer). Draupadi too never likes Karna thereafter. Karna fights and berates the Pandavas at the legendary gambling match during the royal consecration ritual. There, Karna uses the choicest words to insult Draupadi that takes the bitterness of Pandava for Karna to much more emotional level from what previously was a dispute about respective martial prowess. These are the sections of the epic when the Pandavas, Arjuna in particular, openly pledge to kill Karna. Karna retaliates with words too, stating that Arjuna's death is so near that he
