Kronic the Wedgehog (often nicknamed Kronic) was a series of robots that competed in Series 4-7 of Robot Wars. The original version reached the Heat Final in its debut appearance in Series 4 after helping to knock out the seeded Gravedigger, but its successors lost in the first round in Series 5 and the second in Series 6 and 7. However, Kronic 2 was notable for flipping former series champion Panic Attack over in its first round battle during Series 6 to be the last robot standing. The robot's name was a pun on the popular Sonic the Hedgehog video game series.
