Mello (メロ, Mero?), whose real name is Mihael Keehl (ミハエル・ケール, Mihaeru Kēru?), is a fictional character in the anime and manga series Death Note.
Mello is the older of L's three potential successors raised in Wammy's House, Watari's orphanage for gifted children, in Winchester, England, United Kingdom. When it is decided that Mello should work with the other successor, Near, Mello refuses, citing an inability to work with Near, to whom he is considered second in ability. Mello and Near can in many ways be seen as L's best traits split between two people, the result being that each possesses some of L's strengths, but each is also deficient in an inverse area. Near is more intelligent than Mello, but Mello has more ambition than Near. This results in Near thinking things out better than Mello, but sometimes being so uninterested in his surroundings that he verges on inactivity. Meanwhile, Mello has a brazen and driven personality, driving him (and not Near) to be the first to resume actively hunting Kira; however, Mello lets his emotions cloud his judgment, often leading to rash decisions that impede his progress.
