Oh, don't be shy. This bucket of bolts loves living things... so he can make them dead!”— Razer, Jak X: Combat Racing
UR-86 did not appear until partway through the game, hired by Mizo as a mercenary in response to Jak's rising success in the sport of combat racing, posing a threat to his underground gang dominance. Upon introduction, Razer, the retired Kras City Grand Championship champion, admitted even he had to watch out for him.
Nevertheless, he was beaten out by Jak during the Grand Prix of the Red Eco Cup (an event of which he had previously never lost). UR-86 uses the Dragonfly during the Red Eco Cup, the Firebat during the Green Eco Cup, and the Anvil RTX during the Blue Eco Cup, Yellow Eco Cup, and exhibition mode.
UR-86 is a tall and incredibly heavy humanoid robot, known for his "tough, sleek exo-skeleton" that "won't go down easy." He has a silver steel base with crimson armor and round, yellow eyes. While he is a former KG death bot, he does not have any KG insignia, though he does retain off-white stripes on either shoulder pad similar to KG guards.
