Ammo

Ammo is an Autobot from the IDW portion of the Generation 1 continuity family.

Ammo is a member of the Lost Light's crew. He's a Monoformer with early onset Corrodia Gravis, and it's entirely possible he has criminal tendencies.

Fiction

2005 IDW continuity

Ammo was a latter-day constructed cold Transformer: one of the "Made to Order" soldiers, built to repulse the attack on K'th Kinsere. This was in the days when the M.T.O.'s were put through a ten-step program of tests and exams to prove they were "world ready". Twenty Plus One

Trapped in a cell by Chief Justice Tyrest on the legendarily lost Luna 1, Rodimus was informed by Minimus Ambus that amongst his crimes was harbouring a criminal aboard the Lost Light. Trying to guess who among the ship's crew was the culprit, Rodimus picked Ammo fourth, after Whirl, Atomizer, and Lancet. The Divided Self

Ammo was one of the twenty crewmembers who got into the Rodpod when the Lost Light began to disappear. He held several conversations with the rest of the pod's crew before also disappearing, alongside several others. Twenty Plus One

Presumably, he returned along with the others after the quantum duplicate Rewind reset the Lost Light's quantum engines. The Road Not Taken

When Getaway sounded people out about a mutiny against Megatron and Rodimus, Ammo agreed and tacitly allowed Megatron 'sympathisers' to be exiled and put at the mercy of the Galactic Council (though the Decepticon Justice Division ended up finding them first). How Bright Their Frail Deeds

Ammo was later a part of the security team that interrupted the Protectobots' and Mirage's meeting in Swerve's. During the fight, he was knocked down by the Protectobots with a table. Full Circle

Notes

• When Ultra Magnus first cast his eye over the crew manifest of the Lost Light in "How to Say Goodbye and Mean It", he picked out several Autobots whose names begin with "A" that he considered to be potential troublemakers. It's likely that Ammo was one of these.
• In James Roberts's fan-novel Eugenesis, there is an Autobot that is also called Ammo. However, that Ammo was killed and beheaded by Quintesson forces. Ouch.
• And if you dig deep enough into the Transmasters UK fan-continuity, you may come across Ammo's name in Roberts's earlier fanfiction known as The Polyhex Wars. In this piece, he is shown to have a much larger role as a totally epic sniper, previously known as Sights. Whether or not this would match his persona in the IDW canon is unknown, but given the differences between the character Quark in his unofficial fan novel Eugenesis and the Quark in "Shadowplay", it would be best to leave Ammo's personality to the imagination of the reader.
