Sword

Transformers may prefer guns and missiles in their many wars but they are far from above melee combat. Swords are popular melee weapons used by both Autobots and Decepticons.

The Transformers cartoon

 * Megatron gained an energy-bladed sword between the years 1985 and 2005.
 * Menasor sometimes wields a sword with a glowing blade and sometimes wields a normal sword without a flashy aura.
 * Hot Rod wields an energy-bladed sword while sparring with an auto-combatant.
 * The Predacons all wield swords: Razorclaw uses a sonic sword, Headstrong a diffraction sword, Tantrum an electro-sword, Divebomb a laser-guided sword and Rampage a thermo-sword.
 * Most of the Dinobots use energo-swords. Swoop is the exception, using a thermo-sword instead.
 * A thermo-sword as well Weirdwolf wields.
