Kuwaga's always been a little shy, especially when Sapphire's around. – Kabuto the Beetle
Born Blake, he eventually took on the name Kuwaga as a nickname. Kuwaga was raised by his brother and has a very close bond with Kabuto. Since he was a kid, he has harbored a long-time crush on Sapphire the Kelpie from the House of Mythos. His feelings for her are still strong, but he is rather insecure, fearing that their age difference will lead her to believe he is not mature enough for her and that his appearance will deter her. Despite this, he tries subtle ways to woo her and has on many occasions helped her take care of her sister Shamrock.
A future version of Kuwaga is mentioned in chapter 5 of Whitewash by Future Umber as being on patrol with Kabuto for lingering survivors in Crisis City.
