Haplor

Being an Arachnachimp, Haplor bears a strong resemblance to Spidermonkey. However, he has yellow eyes instead of green, his pupils were smaller compared to Spidermonkey, and his fur is a lighter shade of blue, also lacking an Omnitrix symbol and stripes on his tail.

In the Ben 10: Ultimate Alien episode "Simian Says", Haplor, his wife, and daughter were found by Eunice. Shortly after, Eunice fled from Mizaru (another Arachnichimp) and his henchmen, and she helped them hide from the infected Arachnachimps, until Ben, Gwen, Kevin and Simian arrived and found them.

When Eunice left them in hiding, they were captured by Mizaru, who soon turned them into DNAliens. Later, after Mizaru was defeated, all Arachnachimps returned to normal, including Haplor and his family.
