Lambo (ランボ, Ranbo) is a fictional character in the anime and manga series Reborn!

Upon his failure, he starts to live with Reborn's pupil, the future boss from the Vongola Mafia family Tsuna Sawada.

Lambo's character has been well received by readers from the Reborn!, having been featured several times in the popularity poll from the series.

Publications for manga, anime, and other media have commented on Lambo adding praise to and criticism to his appearances in the series.

Lambo dresses in a cow suit complete with a tail, and has a huge afro with horns on the sides of his head which gives him the appearance of a bison.

[2] Although Adult Lambo is shown to be handsome, he remains a crybaby, and is often heard saying things that imply his future involves cleaning toilets.

This version of Lambo is seen as having much more discipline, strength and intelligence than of his past selves, even being capable of almost easily defeating Leviathan during the tournament in the 5-minute effects of the Ten-Year Bazooka.

His weapon is Lampo's Shield, body armor that can give out a huge electrical burst called Corna Fulmine.

In the Simon arc, his ring is rebuilt into the Vongola Helmet which, in its Cambio Forma, becomes full body armor with powerful horns.

Thunder Set is followed by another technique called Electrico Cornata (電撃角) which charges lighting through Lambo's horns and causes severe shock to whoever the attack connects with.

His final ability is an enhanced version of Electrico Cornata in which he can use the electricity in his horns and give it the shape of a blade which makes up for some of its short range.

[14] After leaving the Melone Base, Lambo is trained by Gokudera in the use of rings and boxes to prepare for the fight against the Millefiore's guardians.

[16] On December 5, 2007 Pony Canyon released a Character CD featuring both Lambo and I-pin.

It features various tracks and dialogue composed by both of their voice actors from their child selves: Junko Takeuchi and Li Mei Chan.

[22] Lambo has also been featured in pieces of merchandising based on the series such as cups, apparels, and plush.

While reviewing the first volume from the series, Jarre Pine from Mania Entertainment found Lambo's child appearance to be very appealing for female readers as well as a good way to make various forms of merchandising.

He also found his name to be very hilarious and noted that since he came from a "small line" of the Bovino Family, he thought that there would be a large number of assassins with Lambo's appearance.
