Zarel is one of the cameo bosses found in Mega Man EN. He can be found in a miniature version of Tornado Man's level after accessing a hidden teleporter in Flare Man's stage. He attacks by using several air-based techniques borrowed from other Robot Masters, such as a "reverse" Air Shooter, and a double Tornado Hold. Zarel will also divebomb you to attack.
Reflecting the somewhat silly personality that TJ gave him as a character, Zarel will dance upon defeating you.
On his art, Zarel's legs are in the exact same position of Buster Rod G's, as well as his left hand being similar to Sheep Man's.
