Lero

Lero (レロ, Rero) is a specialized golem that belongs to the Earl of Millennium.

Appearance
Lero is a normal cane umbrella with the addition of a small, talking jack-o-lantern on the tip that acts as his head.

Personality
Lero is a neurotic little being who is often nervous and gets upset easily. However, when behind enemy lines, he has shown a more sadistic side, openly taunting the Exorcists. These sadistic tendencies, though, disappear quickly when he is threatened. Lero tends to add his own name, Lero, to the end of almost every sentence.

Introduction arc
Initially, Lero appears only briefly, being used by the Earl. He doesn't show any sentience and isn't seen talking, only being used by the Earl to summon Akuma, announcing the end of the opening "chapter" with the aid of an alarm clock in his mouth and, at the same time, as a mode of transportation to escape.

Rewinding Town arc
Lero is next seen in the possession of Road Kamelot, who borrowed him from the Earl without permission, as she enters the Rewinding Town. When Road captures Miranda Lotto, Lero is seen again being held by her, though he isn't seen talking. When Road takes Miranda into her dream world with her, Lero nervously reprimands her for skipping school, to which Road responds by telling him that "umbrellas should be quiet."

After her Akuma servants have captured Allen Walker and Lenalee Lee, who have come to the town to investigate the "rewinding" incidents, Road explains to Allen that she is a human, making Lero try to shush her and warn her about going against the Earl's "script" least she be spanked. Again, though, his warnings are ignored, and when Allen and Lenalee begin attacking her, Road takes to using Lero as a mode of transportation.

When Road orders one of the Akuma to self-destruct, she has Lero start a countdown, the Akuma exploding when Lero reaches zero. After all of her Akuma are defeated, Road cheerfully flees with Lero in hand.

Order in Crisis arc
When the Earl brings Tyki Mikk back to the Noah Family base with him, Lero appears briefly, helping Road with her homework and remarking after Tyki leaves that Tyki is very friendly with the humans he hangs out with (Eeez, Momo and Clark).

Edo and Asian Branch arc
Once several key members of the Noah Family return to his side, the Earl heads to Edo, where he uses Lero to summon Akuma. When Lavi attacks him, the Earl uses Lero to escape and stays airborne with him for a majority of the battle, only to later use Lero as a conduit for a devastating attack that levels Edo and nearly kills all of the Exorcists. The Earl then starts sneezing violently, causing Lero to break his silence to check on him.

When Allen Walker arrives, the Earl turns Lero into a sword to use to fight him. Their clash results in a large explosion that the Earl uses to flee onto Noah's Ark with Tyki and Skinn Bolic, where they meet up with Road who asks the Earl where Lero is, apparently intending to borrow him.

Noah's Ark arc
When Allen, Lenalee, Lavi, Yu Kanda, Arystar Krory III and Chaozii Han are pulled into Noah's Ark, they land on top of Lero an flatten him. When Lero recovers and notices them for why they are, he calls them fat and tells them to get off, resulting in Allen and Kanda grabbing him and threatening him. Lero tells them that there is no exit, and then the Earl uses Lero as a microphone to taunt the Exorcists. A large, balloon-form Earl grows out of Lero's mouth, congratulating Lero for having found them before informing the Exorcists that they will remain trapped inside of the Ark as it collapses.

After the balloon Earl floats away, Lero is left behind with the young Exorcists, continuing to tell them as they search for an escape that there is no way out, resulting in Lero getting punched. Tyki arrives to offer the group a key that will help them get on, and when Lero scolds Tyki, Tyki leaves him behind and goes to wait for the Exorcists at the top of a tower in the middle of the Ark.

The Exorcists use the key Tyki gave them to open a door, and when they find Skinn on the other side, Kanda decides to stay behind and fight them, shocking Lero when he threatens the rest when they don't want to leave him.

In the next room, where the group runs into Jasdero and Devit, Lero asks Jasdevi why they aren't on their mission, Jasdevi telling Lero to shut up before they start firing on the group, Lero included, with their guns. As Jasdevi proceed to fight the Exorcists, Lero laughs to himself and thinks about how Jasdevi's guns aren't really loaded. He then asks the twins, again, why they aren't out searching for General Cross Marian, angering the twins and making them fire at him again.

When the twins use their "Trick Glasses" on the group, Lero is hit, as well, and he tries to rub it off on Chaozii's shirt. Lero then watches as the twins summon an "Earl" that fights Allen and fools the group, Lero thinking to himself about the twins' "materialization" powers. Lero then taunts Allen and Krory as they fight the "Earl," accidentally cluing them into the fact that the "Earl" isn't real. After Lavi finds they key, which frees them all from the Trick Glasses, and opens the next door, the twins, who have been seriously injured, form their main Jasdevi body, and after Lero cries out about the room collapsing as the bookshelves begin to explode, Krory forces the others to go on without him, Lero getting swept up in the retreat.

Lero uses this opportunity to taunt the Exorcists once more, telling them that anything could still happen to them. Allen tells Lero that he refuses to give up, making Lero wonder how he can be so calm. They walk through the final door at the top of the stairs, and on the other side Road lunges at Allen and kisses him, to Lero's horror. Road then grabs Lero and walks off with him, liberating him just to use him as transportation once more.

After Allen defeats Tyki with his Sword of Exorcism, Lero notices that Tyki's stigmata have disappeared, and when Road is defeated Lero cries out for her, staying by the unconscious Tyki's side and begging for the Earl to come save them. When the Earl does arrive, Lero immediately flies to his side, crying.

After the Earl's attempt to download the data of the old Ark fails, Lero nervously asks the Earl if the Exorcists had helped the Fourteenth, the Earl not answering as he curses the Exorcists.

Third Exorcists arc
Lero appears briefly when the Earl welcomes Wisely to the family.

Seed of Destruction arc
Lero can be seen by the Earl's side when he's sleeping after the events in the North American Branch.

Abilities and Uses
Flight: Lero has the ability to fly, and carry weights far greater than his own.

Power Conduit: The Earl has been shown using Lero as a conduit for his powers, such as summoning Akuma and unleashing powerful attacks. The Earl has also been shown using Lero to summon his sword, though the extent to which the Earl actually "needs" Lero to do these things is questionable, as he's been seen using his sword without Lero's help.

Trivia
